With 0.9.9.8 officially released, many of the suggestions in this compilation suggestions thread for 0.9.9.8 have been implemented. So at Kornel's suggestion, I'm starting up a new compilation thread for 0.9.9.9, to start a fresh thread and to have a better organized OP that doesn't cover all the stuff that was already implemented or formally rejected, as well as to cover new suggestions.

I'll be maintaining this thread in Icy's absence, and any new suggestions from anyone else is welcomed, no matter how mundane or outlandish the suggestion may be. Before suggesting anything though, I would recommend reading Icy's OP in the aforementioned linked thread, consider the feasibility of being able to implement the suggestion, and backing your suggestions with well-reasoned points, while being open to any feedback your suggestion gets. I'll also note that I do not have any authority with the game nor am I a member of the ChaosForge team, so my own ideas are not above anyone else's, I'm just a passionate player organizing this and offering feedback.

Changes

This thread will be organized into separate posts for changes (which itself will be organized into bugs/exploits/fixes, traits, equipment/items, enemies, special levels, and miscellaneous), everything for badges/medals, and new content ideas. A suggestion marked with an "X" in its box and colored light blue means it has been implemented; a suggestion marked with "~" and colored light green means it has been partially implemented, while a suggestion marked with "~" and colored pink has been soft rejected but may by partially implemented in another way; a suggestion marked with "?" and colored light yellow means an attempt was made to implement it but needs testing to confirm it is working properly, or marks an "issue" that may not be an issue at all; and a suggestion that is struck through and colored red has been officially rejected by Kornel. Each suggestion will additionally have links to the posts explaining the justification for the change and other discussion regarding it.

Bugs/Exploits/Fixes

[?] Bug: The game may lock up on the trait selection screen upon levelling up, where the game still runs with the music playing and you're able to scroll through the background with the mouse, but your trait selection does not register and you cannot exit the screen, forcing you to kill DRL in Task Manager to exit and lose your progress. 1 2 (May have incidentally been fixed in the JHC UI changes, needs thorough testing to fully confirm it has been fixed.)

[~] Bug: Nightmare's -10% speed penalty seems to not be working. 1 2 (Kornel has no recollection of ever adding Nightmare's speed penalty nor likes the idea of difficulties nerfing the player, and after farther testing previous versions back to 0.9.9.6, it may have never actually existed in the first place, or was removed in a very old pre-graphics version. It's up in the air on if this "feature" will be (re)implemented as a universal speed bonus for enemies instead, which needs discussion.)

[ ] Bug: In the latest beta, if you complete a special level on Nightmare/AoD and then exit with any respawns alive, the exit text and mortem history text gives you the level's completion messages, and you'll earn any badges/medals that require completing the level, but the game doesn't actually count the level as completed for Conqueror purposes. 1

[X] Bug: If a former is killed out of vision by something other than you, an error message may pop up stating it failed an attempt to call a table value. This most commonly occurs when a Former Sergeant shoots a barrel and kills himself. 1

[ ] Bug: Corpses will sometimes be ungibbable by explosions and plasma(tic) shotguns for no apparent reason. 1

[ ] Bug: Lightfoot Diamond and Angelic badges aren't being awarded when their criteria is fulfilled, perhaps indirect kills are being counted as "melee" kills? (I can confirm this badge isn't being awarded, unsure what is the cause if it's not the change to indirect kill attribution causing it) 1 2 3

[X] Bug: The melee accuracy bonus of Brute is still not properly applying to thrown weapons. 1

[X] Bug: Sharpshooter doesn't work with explosive pistols, even on direct hits. 1

[X] Bug: In armor and boots assemblies that require a Technical Mod, if the Technical Mod is applied before completing the assembly, the Technical Mod's resistance boosts will stack onto the assembly's resistances, making assemblies like Fireproof Armor more powerful than intended. 1

[ ] Bug: The new modding UI in the latest beta will not allow you to attempt modding non-compatible equipment with Firestorm and Sniper mods, which prevents you from assembling Demolition Ammo (and any future assembly that would require applying them to normally non-compatible equipment). 1

[X] Bug: The Dragonslayer's permanent berserk isn't working, with it granting no additional turns of Berserk at all. 1

[ ] Bug: Using the Dragonslayer's altfire, Whirlwind, can crash the game. It's unclear what conditions causes this crash, as sometimes you can use Whirlwind without the crash happening. 1

[ ] Bug: When initiating a rocket jump, the targeting cursor can extend beyond immediately adjacent tiles, despite rocket jumping only being able to hit immediately adjacent tiles (in previous versions, the game wouldn't let you extend targeting beyond this range). Additionally when initiating a rocket jump with enemies onscreen, the targeting cursor will default onto an enemy, forcing you to move it back to an adjacent tile to rocket jump. 1

[ ] Bug: Projectiles can go through walls without exploding from certain angles, including the outer boundary walls, and explosive projectiles will not explode when clipping. (Needs more thorough testing to fully identify how this bug works). 1

[X] Bug: Ammo stacks dropped by ammo levers are not affected by the difficulty multiplier. 1

[X] Bug: The lava flood in Halls Of Carnage sometimes does not activate. 1 2

[ ] Bug: Screenshots aren't saving properly as of the latest beta, unless you manually create a folder named "screenshot" in DRL's root folder. 1

[ ] Bug: Technician badges may have issues in the latest beta with being awarded properly? (Only a single example so far, where a Technician Gold badge wasn't awarded in the run that finished all basic assemblies, but rather in the run after) 1

[ ] Bug: If too many sounds play in quick succession, the music can get turned off until you enter a new floor or save and reload. 1

[X] Bug: When booting up the game, the loading bar will stretch beyond the screen.

[?] Bug: If a flood event occurs on an island level, it's possible to start in the middle of lava. 1 (This may have been fixed in the old 0.9.9.8 beta, neither I nor Icy have ever experienced this and no one has reported it happening yet.)

[ ] Exploit: The Spider Mastermind can get stuck when shot across the bottom or top middle pillars, making it only able to go up and down. The AI might need to be adjusted. 1

[ ] Exploit: Medical Armor in Nanofiber Skin Armor (N) can allow the player to take 1 damage and immediately heal it. Since this can be done infinitely, it may cause an issue if the total damage value reaches the highest possible. A suggested fix is changing the recharge delay of Nanofiber Skin Armor to 6 so that it can never reach 0. 1

[X] Fix: The Unlock All option doesn't unlock the harder difficulties.

[ ] Fix: The item reveal mechanic when all enemies are dead does not work in Nightmare, it should activate when all enemies are dead at the same time, or after each individual enemy has been killed once. 1

[~] Fix: Damage calculation on direct hits with explosive attacks seem to happen after knockback is applied, resulting in direct explosive hits doing less damage than they should, or possibly no damage at all. 1 2 (Confirmed to be an intentional design choice, but a direct damage component on explosive hits may be added?)

[ ] Fix: The new screen shaking effect should have its intensity based on the strength of the inciting projectile/explosion, rather than shaking at the same intensity regardless. 1

[ ] Fix: The new modding menu can display incorrect info, noticed instances so far is it displaying bulk mods making armors/boots 10% faster rather than -10% slower, and showing you being able to apply more than one of the same mod to armors/boots/melee weapons when you can't. 1

[ ] Fix: The mortem's kill ratio message in the latest beta is based on the total enemy kill ratio with respawns, rather than the unique enemy kill ratio, when it should be based on the latter. 1

[ ] Fix: The character info screen doesn't account for equipped ammo boxes with its displayed reloading speed, when it should.

[ ] Fix: Ironman's trait description is unclear with it stating you get +20% max health, which isn't fully true as Marines still only get +10 HP rather than 12 HP, so it should be reworded to state +10 HP. 1

[ ] Fix: In Scavenger's trait description, update it to clarify that melee weapons, armors, and boots can be scavenged. 1

[ ] Fix: Angel of Humanity's and Archangel of Humanity's descriptions should clarify that Marines start with 12 max HP rather than 20. 1

[ ] Fix: For weapons with very long names (such as the "Burst nuclear plasma rifle"), the name can stretch beyond the available UI space on the HUD, obscuring its ammo. And for armors with very long names, their names will instead stretch into the next line the HUD, obscuring your weapon's name. Whether it be scaling down long names, letting them stretch farther into the HUD, or anything else, something should be done to fix this issue. 1 2

[ ] Fix: When using the Look command, you are unable to scroll the screen with the keys, forcing the use of a mouse to do so. As an obvious detriment to keyboard-only players, this should be fixed. 1 2

[ ] Fix: When equipping a weapon from the ground that auto-equips on pickup, such as Azrael's Scythe, the game will erroneously give the "You don't have [X weapon]!" message. 1

[ ] Fix: Charch's Null Pointer shows that its damage is 0d0, when it's actually 10d1. 1

[ ] Fix: The infinitely spawning Nightmare Demons and Nightmare Cacodemons when equipping the Dragonslayer and Berserker Set severely complicate clearing special levels with said equipment. Either they shouldn't count towards a special level's completion, their spawning should be disabled in special levels, or they should have a spawning limit of some sort. 1

[X] Fix: When the Apostle spawns on the final floor of A100/A666, the ability to see all enemies immediately activates since all enemies technically die when you first enter the floor. Given this is supposed to be a boss fight, this mechanic should be disabled when the Apostle spawns like it is for boss levels. 1

[ ] Fix: Archangel of 666 shows both in-game and in the high scores that it's Ao100. Additionally, the ending mortem says you "finally completed 100 floors of torture". 1 2

[~] Fix: Non-lava fluids are supposed to be able to appear in A100/666 beyond floor 30 for greater level variety, but you still only encounter lava except for in specific level types/events/features that could already have water and acid appear. (Technically this was implemented correctly already but several level types and events with their own fluid generation formulas are overriding it, may get overhauled anyway when blood is added as a new fluid.)

[X] Fix: Elite Former Captains erroneously didn't get the melee damage buff that all the other Elite Formers got. 1

[X] Fix: Nightmare Imps erroneously had two different speed values applied to them. 1

[X] Fix: The player's sprite does not update properly when armor is destroyed. The player additionally doesn't show the proper armor and weapon equipped at the start of challenges and mods that have different starting default equipment. 1

[X] Fix: In the ASCII version, the cursor for the look command does not show and the targeting cursor blends in the invulnerability overlay. 1

[X] Fix: Music resets to max volume regardless of setting whenever booting up the game or entering a new floor.

[ ] Fix: Repeated sounds (such as from several enemies being hit at once) can still get too loud, the sounds should be better staggered out instead of stacking all at once on each other, or perhaps add a limit of some sort that prevents the same sounds from being stacked too loudly on each other. 1 2

[~] Fix: Ensure bridges that go over rivers are not blocked off by walls or rooms without doors. 1 2 (This might be too technically difficult to implement.)

Traits

[ ] Nerf Hellrunner's dodging bonus to +10% per level (needs discussion). 1

[ ] Nerf Vampyre (needs discussion). Some ideas include increasing its prerequisites, disallowing Vampyre from healing beyond 100%, and/or prevent the resistances of berserk from stacking with the resistances of the Marine. 1

[ ] Buff Entrenchment (needs discussion). Some ideas include increasing the resistance bonuses to +50% when chain firing, granting +20% to all resistances when just equipping a chain firing weapon, and some means to allow chain firing longer (such as reduce ammo consumption when chain firing or instant reloading when your clip runs out during chain firing). Alternatively, Entrenchment could be replaced with an entirely new mastery, a la Running Man -> Gunrunner in 0.9.9.7 1

[ ] Give Bullet Dance the additional perk of reloading faster when dual gunning. 1

[ ] Give Fireangel an additional offensive-based perk (needs discussion). One possible idea is when using rocket-based weapons, each shot will get +2 dice in damage calculation. 1

[ ] Buff Gun Kata to have an instant Pistol attack after dodging instead of it being near-instant. Also consider letting it apply Dodgemaster to all enemy projectiles inbetween moves (needs discussion). 1

[ ] Change Gunrunner's prerequisite of Juggler to Finesse 2. 1

Equipment and other Items

[ ] Add sounds for all actions for exotics/uniques/artifacts. 1 2

[ ] Allow Technicians to add a single mod or basic assembly to the following unique armors: Medical Powerarmor, Necroarmor, and Shielded Armor. 1 2 3

[ ] Buff the Chaingun's accuracy to +3. 1

[ ] Increase the Blaster's generation weight to 4. 1

[ ] Frag Shotgun needs farther buffs. One idea to make it standout is to change its damage to 6d3 and decrease its firing speed to 0.5 seconds. Additionally allow it to spawn sooner and be less rare (such as a depth of 10 and weight of 3). 1 2

[ ] Increase the Medical Powerarmor's generation rate to 3 (matching the similarly powerful Necroarmor in rarity). [1

[ ] Let Mega Buster use alt fire to switch modes, but you have to collect all the damage types (more similar to Mega Man). 1 2

[ ] Increase the Mjollnir's generation rate to 2 or 3. 2 3

[ ] Allow Subtle Knife kills to count as "knife kills". Additionally modify it to spawn sooner and be less rare (such as a depth of 7 and weight of 2). 1

[ ] Nerf Trigun's Angel Arm to not be an instant nuke and require 10s like regular nukes. 1

[ ] Farther buff Ballistic Armor by having it retain any plasma and acid resistances the base armor has. 1

[ ] Buff Grappling Boots to retain the base boots' movement speed instead of having a set -10% speed. 1

[ ] Change Nano-shrapnel to a master assembly, with an assembly requirement of PPPN or PPTN. 1

[ ] Change the resistance values that Technical Mods add to boots to be +20% acid and fire resistances while removing the other useless resistance buffs, rather than using the same values they apply to armors. They can keep the +20% plasma resistance as well if the proposed blood fluid is added and utilizes plasma damage. 1

[ ] Buff Agility Mods to give +2 accuracy when applied to melee weapons instead of only +1. 1

[ ] Allow Firestorm and Sniper mods to be applied to melee weapons (needs discussion on exact effects). Current ideas are a Firestorm mod will turn their damage type to fire so they can gib much easier, in addition to possibly increasing the lower of damage die or sides by +1 too, and a Sniper mod will give them the autohit property. 1

[ ] Allow Firestorm mods to be added to explosive weapons with an explosion radius of 1 and 2. If done, consider making the mod give them only a +1 radius boost rather than the usual +2 boost. 1

[ ] Give Sniper mods an effect for Shotguns, instead of doing nothing. One idea is each Sniper mod applied to a Shotgun will reduce its dropoff reduction rate by 1% (so a basic Shotgun with one Sniper mod will have its dropoff damage reduced from 7% to 6% per tile, and if triple modded with Sniper mods, its dropoff damage will be reduced from 7% to 4% per tile). 1

[ ] When a third Sniper Mod is applied to a ranged weapon, have it give the autohit property instead of doing nothing. 1

[ ] Allow the Lava Element to appear as a randomly spawned item. Make its spawning weight 2 or 3, and perhaps give it a spawning depth of 30+ so it can only randomly appear in A100/666. 1

Enemies

[ ] Add sounds for Nightmare enemies, Lava Elemental, Agony Elemental, Arena Master, and Apostle. 1 2

[ ] Add sounds for enemies spawning, enemies reviving, and Archviles charging their attack. 1 2

[ ] Make Cacodemons and Nightmare Cacodemons more aggressive in their attack frequency. Possibly also consider buffing Nightmare Cacodemons to hit slightly harder. (needs discussion) 1

[ ] Farther buff all Elite Formers by increasing their melee accuracy. 1

[ ] Farther buff the Nightmare Archvile by increasing its attack's explosion radius to 2, matching the Arena Master's explosion radius. 1

[ ] Lower the Nightmare Cacodemon's spawning depth in A100/666 to 50+. 1

[ ] Lower the Shambler's spawning depth in A100/666 to 70+. 1

[ ] Increase the Lava Elemental's generation weight to 2 or 3 so it isn't so uncommon in deep levels of A100/666. 1

[ ] Allow the Angel Of Death to spawn in very deep floors of A100/666. Its spawning depth can be either 80+ or 90+. 1 2 3 4 5 6 7

[~] Buff the Apostle to have 500 HP and always teleport after being hit. Also when it dies in A100/666, kill all enemies and end the game like JC. 1 2 3 4 (Apostle has gotten massive resistances instead that makes it drastically more durable, but instant teleportation on hit has not been added yet nor ending the game when it dies in A100/666.)

[ ] Change hunting AI to not ignore items and armors (if implemented, Cyberdemons may need their ability to use items removed or medpacks may need a healing limit of 110 HP to keep them from being potentially too obnoxious). 1 2 3 4 5 6

Special levels

[ ] When special levels are destroyed by a nuke, disable any traps/subsequent enemy spawns they may have from triggering and have the game register them as cleared (this includes Containment Area, City of Skulls, Abyssal Plains, House of Pain, The Lava Pits, and Mt. Erebus) 1

[ ] Make Military Base more difficult as it's still much easier than Phobos Lab. One idea is removing its Tracking Map on UV and N! difficulties. Another idea is if the "patrol" AI flag is added to the game, it could be applied to enemies here so the player cannot rely on camping at the start to kill everything. (Needs discussion) 1

[ ] Change how Schematics drops in Hell's Armory/Deimos Lab work, so that players do not miss out on a rare mod because of them and so each run is truly independent (can probably just have them drop separately from the rare mods). 1 2 3 4

[ ] Have The Wall/Containment Area open up after all enemies are dead to prevent softlocks if you use a Phase Device. 1 2

[ ] Replace the redundant Missile Launcher in City Of Skulls/Abyssal Plains. What to replace it with needs discussion, but one idea is that it can instead be a random guaranteed exotic non-BFG ranged weapon, to make these levels potentially more appropriately rewarding. 1

[ ] In City of Skulls, replace the lever with a horizontal coordinate trap, so that it isn't free to run through. Also extend the middle pillars to go all the way up to the top and bottom of the screen, so that the player is forced to be between the pillars when the trap activates. 1 2

[ ] Buff the enemy layout on the Nightmare! version of City of Skulls and Spider's Lair, as these levels currently have no difference compared to UV (aside from extra HP for the Agony Elemental) and are much easier than their respective counterpart levels (needs discussion). How much to buff them is contingent on if a N! speed bonus for enemies is implemented, but current idea is increasing the amount of Pain Elementals in City of Skull's second wave, and replacing a third of the Arachnotrons with their Nightmare variants in Spider's Lair. 1

[ ] The Nightmare! version of The Vaults was supposed to give each of the six Barons in the right vault a set of Red Armor to pick up, but currently it seems only one Red Armor is spawning. Additionally, have the two teleporters in the center vault have their teleport destinations be on opposite ends of the map, so a player cannot easily camp the teleport locations to safely kill each of the center vault's Nightmare enemies. 1

[~] If you don't have the Arena Master's Staff, you can softlock in House Of Pain on Nightmare and in Angel Of Darkness from dead enemies reviving while you're locked in another room, so something should be done to prevent this softlock. 1 (Enemy respawning has been disabled on the level altogether for the timebeing, may be temporary if another solution is figured out to prevent softlocks while enabling respawning.)

[ ] In House Of Pain, make using the Arena Master's Staff required to access the Large Health Globes on the level. 1

[X] Define a default song to play for House Of Pain in the music.lua file, so that it doesn't play a random song at default that will likely be unfitting. Suggestions for the song to use are either Sign Of Evil (i.e. E1M8's track) or Dark Secrets (i.e. The Vaults' track).

[ ] Make Unholy Cathedral more difficult (needs discussion). Current suggestion is increasing the Demon count on HMP to match current UV/N!, then replacing half of them with their Nightmare versions on UV, and replacing all of them with their Nightmare versions on N!. 1

[ ] Add ammo pickups to The Mortuary, to compensate for respawns no longer dropping ammo. Current idea is an ammo box in each corner, and double them on Nightmare. Consider adding ammo to Limbo on Nightmare too if changes are made to make it more difficult. 1

[ ] If Blood is added as a new fluid, replace the lava in Limbo with it. 1

[ ] In The Lava Pits and Mt. Erebus on Nightmare difficulty, remove the last Radsuit, so that there is no Radsuits on the level at all. 1

[ ] Prevent being able to teleport into the "mountain" on Mt. Erebus, so that the player does not end up potentially softlocked 1 2 3 4

[ ] Make Mt. Erebus more difficult (needs discussion). Some ideas include adding Cacodemons separately from Lost Souls/Pain Elementals (and then replacing them with their Nightmare versions on UV/N!), increasing the number of Revenants and Mancubi on UV/N! (or possibly even replacing them with Nightmare versions if they're added to the game), and/or having to fight two Lava Elementals as the boss fight instead of one. 1

[ ] Disallow nukes from being activated in Hell Fortress altogether. Additionally have any active powerups get turned off when entering Hell Fortress, so you cannot take an Invulnerability or Berserk stack into Hell Fortress to trivialize it. 1

[ ] Improve the Apostle fight in Hell Fortress. Suggestions include giving it unique entrance text, unique victory text, and have the fight spawn a ton of corpses of strong enemies when entering the level, so that the Apostle's resurrecting capabilities get utilized. 1

Miscellaneous

[ ] Have dying to John Carmack count as a normal death instead of as a partial win. 1

[ ] Add method for guaranteed Berserker Armor and Dragonslayer in Angel of 100 / Archangel of 666, so that full wins in A100/666 aren't terribly luck-based. 1 2 3 4

[~] Obtaining high scores mostly devolve into playing Archangel of 666 and aren't really used as a means to compare runs. Perhaps they should be changed (needs discussion). 1 (High scores have been separated into their own individual boards for each challenge, so A100/666 scores will no longer dominate a player's high score leaderboard.)

[ ] Give EXP for pulling levers (but consider disabling this bonus if the player has Intuition) 1

Medals, Badges, and Rankings

This post is for everything regarding medals, badges, and rankings. This is primarily fixing redundant or realistically unwinnable medals/badges, and bringing up the count of Angelic badges to be equivalent with the count of the other badge tiers. Any ideas for new medals and badges will also be here though.

[ ] Add color-coding to medals and badges in mortems at the end of a game. 1 2

Medals

[ ] Change "Shotgunnery Cross" and "Marksmanship Cross" to each require 100% kills, so that they're not redundant with the Angel of Shotgunnery and Angel of Marksmanship challenges, and so that you can't cheese obtaining them in a pacifist run. 1

[ ] Change "Malicious Knives Cross" and "Sunrise Iron Fist" to require 50+% kills, so that you can't cheese obtaining them in a pacifist run. 1

[ ] Allow Gargulec Medal to be obtainable alongside Gargulec Cross if you haven't already gotten it, like how it works with other lesser versions of other medals. 1

[ ] New: Experience Token - Reach experience level 15 (excludes Angel of 100 and Archangel of 666). 1

[ ] New: Aurora Star - Find 10 uniques or more in a single game (Allow all challenge types). 1

[ ] New: Technician Medal - Create 15 or more different assemblies in a single game. (Allow all challenge types) 1 2 3

[ ] New: UAC Cross - Kill 2,500 or more enemies. (Allow all challenge types) 1 2 3

[ ] New: Boss Slayer Cross - Clear a boss floor and exit alive. (Boss floors are special floors where all enemies are a boss, which are Bruiser Brothers, Shamblers, Agony Elementals, Lava Elementals, or Cyberdemons. This does not include Phobos Anomaly, Tower of Babel, Dis, and Hell Fortess). 1 2 3 4 5 6

[ ] New: Unexplored Star - Visit no generated levels and win the game. (Excludes Angel of Confidence, Angel of Overconfidence, Angel of 100, and Archangel of 666) 1 2 3 4 5 6

[ ] New: Keen's Helmet - Defeat John Carmack without getting damaged. 1

[ ] New: A medal for completing a Conqueror run in any of Angel of Red Alert, Darkness, Impatience, Purity, and Masochism (name needs discussion). 1

Badges

[ ] Disallow Dual-Angel challenges for all badges that require performing a feat on a specific challenge. This includes Berserker Bronze Badge to Pacifist Bronze Badge, Berserker Silver Badge to Pacifist Silver Badge, Berserker Gold Badge to Arena Gold Badge, Berserker Platinum Badge to Everyman Platinum Badge, and Reaper Diamond Badge to Arena Diamond Badge. 1

[ ] Allow previously obtained badges to appear in mortems, and keep count of them. To prevent the awards section of UV/N! mortems from becoming absurdly large, have only the highest tier of each badge appear on the mortem 1 2

[ ] Have more badges require at least a standard win, rather than any win. Current suggestion is every Gold, Platinum, and Diamond badge that requires winning the game should require at least a standard win, with the exceptions of those that already require a full win and Pacifist Gold. 1

[ ] Have higher rankings require more of the previous tier badges (get to needing 15 Bronze, and then a few rankings later, start requiring them again for 18 Bronze, 21 Bronze, etc). 1

[ ] No-Life King ranking should require all badges of every type. Currently it only requires Angelic Badges. 1

[ ] Change Heroic Bronze/Silver/Gold/Platinum/Diamond Badges to require 10%/30%/50%/70%/90% of total medals respectively, so that the series remains proportional as new medals are added. 1 2

[ ] Add a new set of badges for House of Pain, since the Scavenger series doesn't work for it (as it doesn't require luck to complete without the Staff). You can read my linked post for ideas on what do for the badges. 1

[ ] Add a new set of badges for The Chained Court (needs discussion on badge requirements, linked post has my current ideas). 1

[ ] Add a new set of badges for Phobos Lab and Military Base (needs discussion on badge requirements, linked post has my current ideas). 1

[ ] Add a new set of badges for Hell's Armory and Deimos Lab (needs discussion on badge requirements, linked post has my current ideas). 1

[ ] Veteran Bronze Badge - Change this to requiring a standard game so that it's at least a bit different than Medal of Prejudice. 1

[ ] Speedrunner Bronze Badge - Change this to 40 minutes so that it's a little different than Compet-n Silver Cross. 1

[ ] Arena Bronze Badge - Change this to requiring a standard game so that it's at least a bit different than Hell Champion Medal. 1

[ ] Gatekeeper Gold Badge - Change to passing Phobos Anomaly on Hurt Me Plenty difficulty without taking damage, so that it isn't practically the same as Cyberdemon's Head and is less trivial. Alternatively, change it to both passing Phobos Anomaly + clearing Tower Of Babel without damage on at least HNTR. 1 2

[ ] Berserker Platinum Badge - Remove the kill count requirement, so that it isn't too similar to Gargulec Cross. 1 2 3

[ ] Hunter Platinum Badge - Change to Ultra-Violence and needing 75+% kills, as there's little reason to go for this badge instead of jumping straight to Hunter Diamond and UV is nonsensically skipped in this badge series. 1 2 3 4

[ ] Everyman Platinum Badge - Change it to requiring 100% kills, so that it isn't the same as Thomas' Medal. 1

[ ] Longinus Platinum Badge - Change it to beating Unholy Cathedral without Brute on any difficulty. Also disallow Angel of Max Carnage and Light Travel from being able to earn it. 1

[ ] Berserker Diamond Badge - Remove the kill count requirement and instead require the newly suggested medal "Unexplored Star" for a more unique and fitting challenge. 1 2

[ ] Centurial Diamond Badge - Change this to require the Experience Cross in addition to Nightmare difficulty, so that it isn't the same as Dervis' Medallion. 1

[ ] Daredevil Diamond Badge - Change this to require 100% kills, as it is too easy for a Diamond badge, and it makes little sense to require less kills in AoOC than in Elite Diamond, which requires 90% kills in a standard game. 1

[ ] Longinus Diamond Badge - Disallow Angel of Max Carnage and Light Travel from being able to earn it. 1

[ ] UAC Angelic Badge - Change to requiring Ultra-Violence, as it is realistically unwinnable. 1 2

[ ] Strongman Angelic Badge - Change to requiring 75+% kills, so that it is less tedious and more realistic without farming Pain Elementals. 1

[ ] Speedrunner Angelic Badge - Change to requiring 12 minutes or less, as it is realistically unwinnable. 1 2 3

[ ] Demonic Angelic Badge - Change to winning a standard game on Nightmare with 100% kills and Untouchable Medal or even an Untouchable Pin, as it is realistically unwinnable. Perhaps consider something else entirely, as long as it's changed to something that's realistically possible and isn't just a harder version of another Angelic badge. 1 2 3 4

[ ] Shottyman Angelic Badge - Change to requiring 100% kills, as it is too easy for an Angelic Badge, even with the Nightmare changes that eliminates the cheese of farming respawns to buff the kill count. 1 2

[ ] Pacifist Angelic Badge - Change to requiring Nightmare and remove the kill count requirement, as it is realistically unwinnable without absurd save scumming. 1

[ ] New: Heroic Angelic Badge - Achieve all medals. 1 2 3

[ ] New: Destroyer Angelic Badge - Complete Angel of Max Carnage + Angel of 100 on Nightmare with Untouchable Pin. 1

[ ] New: Hunter Angelic Badge - Complete the proposed Archangel of Darkness on Nightmare. If this challenge isn't created, instead go with Angel of Darkness on Nightmare as a conqueror. 1 2 3

[ ] New: Daredevil Angelic Badge - Complete Angel of Overconfidence + Angel of Darkness on Nightmare with 100% kills. 1

[ ] New: Purist Angelic Badge - Complete Angel of Purity + Angel of Light Travel on Nightmare. 1

[ ] New: Carnage Angelic Badge - Complete Angel of Max Carnage + Angel of Masochism on Nightmare with 100% kills. 1

[ ] New: Apostle Angelic Badge - Kill the Apostle in a standard game on Nightmare. 1

[ ] New: Sunrise Angelic Badge - Complete Angel of 100 on Ultra-Violence with 100% kills using only Fists. 1

New Content

This post will cover all suggestions for new content to add to the game. It is organized by general features, equipment/items, enemies, new challenges, and miscellaneous stuff (a traits and special levels section could be added too if Kornel says they're on the table and anyone has decent suggestions for them).

Features

[ ] Have the trait selection screen be more color-coded (example by Mader Levap): 1 2

Spoiler (click to show/hide)

[ ] Add a toggle for turning off the powerup overlays of Berserk, Invulnerability, and Envirosuit. 1 2

[ ] Add a toggle to enable legacy inventory selection (where each inventory slot was instantly selectable by an associated letter key) for players who preferred that method. 1 2 3 (Too technically difficult to implement)

[X] On the UI bar, in the empty right side of it, show the total amount of loose ammo in your inventory for your equipped weapon (or the ammo left in your equipped ammo box if you have one equipped). 1

[ ] When playing Nightmare or Angel of Darkness, have a message that informs you when every unique enemy on the floor has been killed at least once, so that a player going for 100% kills but not meticulously disposing of every corpse doesn't need to keep bringing up the player info screen to check when they have gotten 100% kills on any floor. Also maybe consider adding a visual indicator to respawned enemies to help immediately discern them, such as some dull-colored aura? 1

[ ] Consider having a time display in the player info screen? 1

[ ] Create/readd locked vaults, as they're described on the wiki. 1 2

[ ] Add trap rooms. These would have a power-up/exotic/unique item inside, and when picked up, has a randomized chance of spawning enemies similar to a summon enemies lever, or floods the room with acid or lava. The weight of the power-ups/exotics/uniques would not impact the rest of the floor, and any enemies spawned by the trap will not give EXP. The chance of the trap activating can be affected by depth level and/or difficulty. 1 2 3 4 5

[ ] Add support for more music slots beyond level 25 in the music.lua file, so that players have the option for more different music to play in A100/666 if they desire. 1

Equipment, assemblies, and other Items

[ ] New common Pistol type (suggested example is "Magnum" with more power and less accuracy). 1 2

[ ] New exotic: Acid-Proof Armor, which is 3 Protection, 95% Acid Resistance, -10% movement speed, everything else normal. (Could alternatively be named "Baron's Hide" to have a more flavorful name) 1 2

[ ] New exotic: Glass Armor, which is 0 Protection, 50% Durability, 50% all resistances. 1 2

[ ] New exotic: Glass Shield, which is 0 Protection, 50% Durability, 80% all resistances, cannot be repaired, cannot be modded, doesn't degrade. 1 2 3 4

[ ] New unique: Dimensional Boots, which is 4 Protection, -30% Move Speed, +30% Knockback, and when worn, you move two tiles for each movement rather than the usual one tile. 1

[ ] New assembly: Scouting Armor (any armor + AS), which is original with +1 Vision, +10% speed. 1

[ ] New assembly: Blastproof Armor (any armor + TF), which is original with half damage to explosions, +30% knockback. 1

[ ] New assembly: Grappling Armor (any armor + BA), which is original with +30% Melee Resistance, -50% knockback. 1 2 3 4

[ ] New assembly: Sniper Rifle (Chaingun + BAS), which is original with auto-hit property. 1 2

[ ] New assembly: Laser Blade (Combat Knife + BTN), which is 5d5 plasma damage with 0.8 sec firing speed, -2 accuracy, and when equipped, it has the ability to reduce any plasma hit that deals less than 5 damage before armor/resistances to 0 (or alternatively gives +50% plasma resistance). 1

[ ] New set: Tactical Set (Tactical Armor + Tactical Boots), which gives Dodgemaster. 1 2

[ ] New set: Bruiser Set (Acid-Proof Armor/Baron's Hide + Acid-Proof Boots), which gives 100% acid resistance. 1

Enemies

[ ] New enemy: Nightmare Revenant, which is much faster, hits much harder in melee, and swaps its fire damage and resistance for plasma damage + resistance. (Exact stats to be discussed, view linked post for current suggested numbers). 1

[ ] New enemy: Nightmare Mancubus, which is far tankier, hits much harder in melee while having melee resistance, and its projectiles deal acid damage while being able to leave behind acid tiles. (Exact stats to be discussed, view linked post for current suggested numbers). 1

[ ] New monster group: 2 x Baron of Hell, 2 - 6 x Nightmare Imp, with a minimum depth of 30, maximum depth of 60, and a weight of 4. 1

[ ] New monster group: 2 x Bruiser Brother, 4 - 9 x Nightmare Imp, with a minimum depth of 60, and a weight of 3. 1

[ ] New monster group: 4 - 9 x Nightmare Demon, with a minimum depth of 50, and a weight of 3. 1

[ ] New monster group: 3 - 6 x Nightmare Arachnotron, with a minimum depth of 70, and a weight of 2. 1

[ ] New monster group: 1 x Elite Former Sergeant, 2-6 x Elite Former Human, with a minimum depth of 60, maximum depth of 80, and a weight of 4. 1

[ ] New Monster group: 1 x Elite Former Captain, 2-3 x Elite Former Sergeant, 2-3 x Elite Former Human, with a minimum depth of 70, maximum depth of 90, and a weight of 3. 1

[ ] New monster group: 1 x Elite Former Commando, 2-3 x Elite Former Captain, 2-3 x Elite Former Sergeant, with a minimum depth of 80, and a weight of 2. 1

[ ] New monster group: 2-3 x Lava Elemental, 2-3 x Shambler, with a minimum depth of 70, and a weight of 1. 1

[ ] New monster group: 1 x Agony Elemental, 3-8 x Nightmare Cacodemon, with a minimum depth of 80, and a weight of 2. 1

[ ] New monster group: 1 x Cyberdemon, 4-9 x Baron of Hell, with a minimum depth of 80, and a weight of 2. 1

[ ] New monster group: 1 x Cyberdemon, 3-6 x Bruiser Brother, with a minimum depth of 90, and a weight of 1. 1

[ ] New monster group: 2 x Nightmare Archvile, 3-6 x Mancubus (or 2-4 x Nightmare Mancubus if they're added), 3-6 x Revenant (or 2-4 x Nightmare Revenant if they're added), with a minimum depth of 90, and weight of 2. 1

New challenge ideas

[ ] "Angel of Gladiating" and "Angel of Labyrinth" (or any other appropriate name): The former challenge will have all floors be Arena-type levels, and the latter challenge will have all floors be mazes. 1

[ ] "Angel of Misfortune" (or any other appropriate name): Every floor will have a level event. 1

[ ] "Angel of Spilling" (or any other appropriate name): Your inventory will be reset to the starting loadout upon entering every floor. The starting loadout may be modified so you're not practically forced to use Pistol builds, exotics/uniques may have increased chances of spawning to compensate for the temporary equipment, and an exception could be made for entering boss and special levels, so that they remain beatable. 1

[ ] "Archangel of Darkness": You have a vision radius of 4 and enemies revive, but you gain x2.5 experience. 1 2 3 4 5

New level events

[ ] "Mortuary event": All enemies will immediately die when entering the floor, then a random number of Arch-Viles will be spawned around the floor (and especially bad level rolls on UV/N! could spawn Nightmare Arch-Viles). Also disable the "reveal enemies" mechanic and stair sense in this event. 1

[ ] "Max Carnage event": Emulates Angel of Max Carnage for a single level, i.e. the player and enemies always deal maximum damage while having +12 accuracy. Particularly bad level rolls should instead have a "Snake Eyes" event, where only enemies deal maximum damage and have +12 accuracy. 1

[ ] "Masochism event": Emulates Angel of Masochism for a single level, i.e. the player will be unable to heal until they exit the floor. To prevent a player from getting screwed by entering such a floor at low health, have the player get supercharged upon entering the floor. 1

Miscellaneous

[ ] New fluid: Blood, which deals 8 damage, and while it harms the player, it does not harm enemies. (Needs discussion on damage type, it could just be Plasma, so that a third resistance type is relevant to boots, but some boots will need that resistance added). 1

[Omega Tyrant]

I'll use this post to explain my rationale for the new suggestions I added to the OP while making it.

*Farther buff all Elite Formers by increasing their melee accuracy.

Elite Formers were given a substantial buff to their melee damage to make them less exploitable and weaken camping strats in Military Base. However, I realized their accuracy wasn't buffed either, and their accuracy with melee attacks range from mediocre to terrible, limiting the impact of their melee buff as even on UV/N! they'll miss you often with their melee attack. Just buffing them all by +2 should suffice.

*Lower the Nightmare Cacodemon's spawning depth in A100/666 to 50+.

I noticed the Nightmare Cacodemon has a spawning depth of 51+, which looks like a typo, when all other enemies from floor 30 onward have spawning depths that are a multiple of 10, with this lone exception. So that should be corrected.

*Lower the Shambler's spawning depth in A100/666 to 70+.

When looking over when the later enemies start spawning in A100, while floor 60 only introduces one new enemy (Elite Former Sergeant) and floor 70 introduces two enemies (Elite Former Captain and Lava Elemental), floor 80 introduces a whopping four of them. So this suggestion is to more even out when new enemies get introduced instead of having this big spike at floor 74-80, of which the Shambler in that floor 80 group makes the most sense to have spawn sooner.

Give EXP for pulling levers (but consider disabling this bonus if the player has Intuition)

On Discord, after someone erroneously thought that levers gave you EXP, Kornel stated he thought that could be a good idea, and I think it can be too, so I want to formally propose it, to farther incentivize gambling with levers. I would also suggest possibly disabling that EXP bonus if you have Intuition, so that Intuition doesn't get buffed farther.

Change "Shotgunnery Cross" and "Marksmanship Cross" to each require 100% kills, while also changing "Malicious Knives Cross" and "Sunrise Iron Fist" to require 50+% kills

Aside from the former two new medals being redundant with the already existing challenges where you're restricted to only using Shotguns and Pistols, I discovered you can easily cheese getting them alongside the Malicious Knives Cross, Sunrise Iron Fist, and the new Zen Master Cross all in a single pacifist run (as you can see in this mortem I posted to the Discord). Ignoring the blatant cheesing to get a bunch of obtuse medals at once, this seems to be clearly against the spirit of these medals where you're supposed to be actually killing enemies with the designated weapon type. A simple solution would be adding a 100% kills requirement to the Shotgunnery and Markmanship Crosses (that additionally has the bonus of making them somewhat distinct in purpose from the pre-exisiting shotgun/pistol challenges), while adding a 50% kills requirement to the Malicious Knives Cross and Sunrise Iron Fist. You could technically still get them all in a single 100% kills fist-only run, but that takes a ton more effort than spamming pacifist runs until you get lucky (and at least you wouldn't be able to double them up with the Zen Master Cross and Pacifist Medal).

*Allow previously obtained badges to appear in mortems, and keep count of them. To prevent the awards section of UV/N! mortems from becoming absurdly large, have only the highest tier of each badge appear on the mortem

Being able to reobtain badges was shot down by Kornel, under the reasoning that it would make Nightmare mortems' award sections become hugely inflated. I agree with that reasoning but still would like this idea, so I want to propose amending it to where you can reobtain badges, but only the highest tier badge of each set will appear in the mortem's awards section (for example, if you fulfill the conditions to earn the Veteran Diamond Badge, none of the lower tier Veteran Badges will appear in the mortem). The main cause of this potential inflation is that obtaining the higher tier badges will also fulfill the requisites for all the lower tier badges in the set, with only a few exceptions, so this should prevent the award section from becoming too inflated in size with redundant badges.

*Add a new set of badges for House of Pain

Currently the Scavenger set of badges do not apply to House of Pain. You could simply include House of Pain in this badge set, but given that unlike The Vaults, House of Pain is conventionally beatable without the Arena Master Staff, so getting the Scavenger badges on it would be much much easier. Considering that, House of Pain should have a new set of badges for it. The requisites need to be hammered out, but I have the following ideas:

Homewrecker Bronze: Enter House of Pain, and decline the invitation.
Homewrecker Silver: Clear House of Pain.
Homewrecker Gold: Clear House of Pain on HMP or higher without using the Arena Master's Staff.
Homewrecker Platinum: Clear House of Pain on UV or higher in Angel of Confidence.
Homewrecker Diamond: Clear House of Pain on N! in Angel of Overconfidence.
Homewrecker Angelic: I'm at a loss for this one and really need ideas, maybe clear it on N! without using the Arena Master's Staff in an Angel of Purity + Angel of Humanity dual challenge? (i.e. beat it on N! with no health and no powerups)

*Change Everyman Platinum Badge to requiring 100% kills, so that it isn't redundant with Thomas' Medal.

Kornel has stated that he doesn't want to change any of the medals named after old players, named after them for being the first players to achieve that medal's particular feat. So if changing Thomas' Medal is off the table, then Everyman Platinum should be changed to not be redundant. One idea is to change Everyman Platinum to require 100% kills instead of being a conqueror, so that it remains a tough platinum badge that is still available to obtain on HNTR difficulty.

*Change Centurial Diamond Badge to require the Experience Cross in addition to clearing A100 on Nightmare difficulty, so that it isn't redundant with Dervis' Medallion

Similarly, if changing Dervis' Medallion is off the table, then Centurial Diamond Badge should be changed to not be redundant. My idea is to make it also require obtaining the Experience Cross, so you must actually kill most enemies to max out your level instead of just trying to stair dive through, but you don't have to go through the tedium of destroying all corpses or repeatedly killing a reviving enemy as kill percentage doesn't matter unlike with many other badges.

*Add the Bruiser Set (Acid-Proof Armor/Baron's Hide + Acid-Proof Boots), which gives 100% acid resistance.

If the Acid-Proof Armor (or Baron's Hide as I think it could be named) is added, it makes an obvious pairing with the Acid-Proof Boots, that can work as a weaker counterpart to the Inquisitor Set with full acid immunity instead of fire immunity, while also giving the underutilized Acid-Proof Boots a bit more potential usage.

*Add new monster groups for deeper levels in Angel of 100/666

0.9.9.8 added a new monster group of Pain Elementals + Cacodemons that spawns exclusively in A100/666 as its minimum depth is beyond standard game limits, which got me thinking that there could be more groups added to shake up deeper A100/666, utilizing the nightmare and boss enemies that have no such groups. Plus seeing the 100th Archvile + Barons/Revenants/Mancubus group gets repetitive, so more promotion of variety is nice and helps to make deeper A100 floors a bit more potentially dangerous. Several new monster group ideas I have:

2 x Baron of Hell, 2 - 6 x Nightmare Imp, with a minimum depth of 30, maximum depth of 60, and a weight of 4 (an upgraded version of the Baron + Imps group that stops spawning after floor 21).

2 x Bruiser Brother, 4 - 9 x Nightmare Imp, with a minimum depth of 60, and a weight of 3 (a farther upgraded version of the aforementioned group).

4 - 9 x Nightmare Demon, with a minimum depth of 50, and a weight of 3 ("Phobos Lab flashback", an upgraded version of the mass Pinky group that stopped spawning dozens of floors ago).

3 - 6 x Nightmare Arachnotron, with a minimum depth of 70, and a weight of 2. ("You can't tank this", an upgraded version of the mass Arachnotron group, though accordingly more uncommon).

1 x Elite Former Sergeant, 2-6 x Elite Former Human, with a minimum depth of 60, maximum depth of 80, and a weight of 4 ("Elite platoon", an upgraded version of the old Former Sergeant + Former Humans group)

1 x Elite Former Captain, 2-3 x Elite Former Sergeant, 2-3 x Elite Former Human, with a minimum depth of 70, maximum depth of 90, and a weight of 3 ("Elite platoon Mark 2", a farther upgraded version of the Formers-only group that utilizes the newly spawning Elite Former Captain).

1 x Elite Former Commando, 2-3 x Elite Former Captain, 2-3 x Elite Former Sergeant, with a minimum depth of 80, and a weight of 2 ("Elite platoon Mark 3", an even greater upgraded version that brings out all the big guns).

2-3 x Lava Elemental, 2-3 x Shambler, with a minimum depth of 70, and a weight of 1. ("Fireblu", a rare yet potent combination of lava and plasma, plus these two guys both teleport and regenerate, while not making good group buddies with anyone else).

1 x Agony Elemental, 3-8 x Nightmare Cacodemon, with a minimum depth of 80, and a weight of 2 ("The Dark Cloud", a significantly more threatening version of that cute meatball cloud group we've been seeing for the past 50 floors).

1 x Cyberdemon, 4-9 x Baron of Hell, with a minimum depth of 80, and a weight of 2 ("Tricks And Traps", a homage to one of Doom 2's most famous setpieces, unfortunately this time you can't make them fight each other).

1 x Cyberdemon, 3-6 x Bruiser Brother, with a minimum depth of 90, and a weight of 1 ("You can run but you can't hide", a rare upgraded version of the former group, as aside from Cybie having even beefier backup, this time they will all be hunting you alongside him).

2 x Nightmare Archvile, 3-6 x Mancubus (or 2-4 x Nightmare Mancubus if they're added), 3-6 x Revenant (or 2-4 x Nightmare Revenant if they're added), with a minimum depth of 90, and weight of 2 ("Nightmare VMR", of course we need the upgraded version of this classic trio group to round out the end of A100).

Add a new fluid, Blood, which deals 8 damage, and while it harms the player, it does not harm enemies.

Kornel mentioned the possibility of adding a new fluid, and when thinking of it, we're missing the third classic damaging fluid from Doom, blood. To make it more interesting, I think it should do substantially less damage than lava at 8 damage, but it should be even harder to get good foot protection against it (perhaps it should utilize plasma damage?), and it has the farther unique effect of being a fluid that doesn't damage enemies, making it a more serious impediment than lava can be (which you can normally exploit to great effect against most enemies, whether to escape them, corral them to a favorable position, or knock them into it to severely injure or kill them). It should be made to only generate in Hell and beyond, and be a bit uncommon, while you can also add it to the pool of lever effects. If it's added, some boots may need the relevant (assumed plasma) resistance added, of which I propose the following:

Plasteel Boots -> 10% plasma resistance (just so it saves you one more point of damage than what Protective Boots would)
Environmental Boots -> +30% plasma resistance (should take more than an advanced assembly with cheap mods to get that good of resistance to it)
Cerberus Boots -> +95% plasma resistance (I don't think they should have full blood immunity, so that this fluid is much more difficult to get immunity to)
Nylaptotep Boots -> 30% plasma resistance (matching Malek's Armor)
Enviroboots -> 100% plasma resistance (should be the only boots immune, also gives it a niche over A-modded Cerberus Boots that otherwise obsoletes it)

Maybe could also add new standard or exotic boots that only has a good plasma resistance and nothing else (and if exotic, perhaps a minor speed bonus too just to make it a bit more unique, as currently only Phaseshift and Laptop boots make you faster at base)

Thanks for the compilation, Tyrant.

A small U/X suggestion based on my recent experiences with DRL:
It would be convenient if we had a way to show how much ammo is left in your inventory for the current weapon you're wielding. Feels like there's space to the right of the weapon itself, at least.
I know you can open the menu to look, but not having to stop the action to look and keep track may make gameplay flow better, especially with ammo-hungry stuff like rapids.

There's a lot to go through and respond to here, but for the moment, +1 to having an upgrade to the basic pistol that isn't a special drop you could never see in a given run.

EDIT: Also, after once again staying up until almost 3 AM playing the game, I think it'd be -extremely- helpful to have a clock display somewhere >~<
It can maybe be toggled or something but it'd certainly help with keeping track of time, especially when playing in fullscreen.
ToME has this as an add-on and it's probably the only reason I don't stay awake playing until ungodly hours

Having an ammo display on the UI bar would be convenient and there is certainly space for it. Main issue is ammo boxes and other weapons of the same type with ammo in them, but I would imagine that it wouldn't count them since that isn't ammo you can readily reload with. And if you have an ammo box equipped, it could instead show the ammo left in it.

As for a time display, I personally don't see much use for it, but it is one of those "sure why not" things, as long as there's a clean spot in the UI to fit it in (and it of course isn't too much a pain to program in).

Updated the OPs to include this and a more up-to-date bug list.

[Khashishi]

I miss the ability to select items by pressing a letter key corresponding to each row of the inventory. It is much more efficient than scrolling to the item and pressing enter. Both methods of selection should be available.

The volume of the sound from using the arena master staff on multiple enemies should be reduced, or it should only be played once regardless of enemy count.

I'm not sure if knockback has been fixed; I haven't tested enough 0.9.9.8. But in 0.9.9.7 knockback occurred at a different time to damage, so hitting enemies with tactical rockets would frequently cause them to get knocked back but take no damage. Also, I think that you can get knocked back twice by enemies with splash damage if they knock you back into a tile where the splash hasn't resolved yet. I'm not sure how this affects damage.

I suggest not basing knockback distance on damage so that son of a bitch doesn't increase knockback. This is a nerf to son of a bitch, which is very powerful. You could add increased knockback to the reloader trait, which would synergize well with the shotgun and rocket focus, though you might need to change the name of the trait.

Maybe a guaranteed combat pistol somewhere would be nice, like in Phobos lab.

UI change: When using look mode, the screen should scroll if you try to look near the edge of the screen. I'm not sure if there's a way to scroll the screen without using the mouse, but I don't like using the mouse to check around the map.

[Omega Tyrant]

I miss the ability to select items by pressing a letter key corresponding to each row of the inventory. It is much more efficient than scrolling to the item and pressing enter. Both methods of selection should be available.

I personally hated this and was glad to see it removed, as too many times I misclicked on the inventory screen and it made me waste a medkit or other consumable item. I suppose there is no harm though in adding it as a toggle in the legacy settings if people really want it back though (assuming there is no coding complications with it).

The volume of the sound from using the arena master staff on multiple enemies should be reduced, or it should only be played once regardless of enemy count.

This is a problem in general with how repeated sounds being played at once have their audio stacked together. This was pointed out in the 0.9.9.8 thread and some adjustments were made for it (notably, tripping a wall destroying lever no longer breaks your ear drums), but more could be done.

I'm not sure if knockback has been fixed; I haven't tested enough 0.9.9.8. But in 0.9.9.7 knockback occurred at a different time to damage, so hitting enemies with tactical rockets would frequently cause them to get knocked back but take no damage.

This is already reported in the OP, being the second point in the bug report section.

Also, I think that you can get knocked back twice by enemies with splash damage if they knock you back into a tile where the splash hasn't resolved yet. I'm not sure how this affects damage.

Could you elaborate on this, and perhaps accompanied by screenshots demonstrating it, because I'm not understanding what it is you're reporting here. If you're just saying that some hits can knock you back two spaces, then that's a completely normal function of the knockback mechanic, where any shotgun blast and non-BFG explosive hit knocks you back by one tile per 7 damage before armor/resistances, and so an explosive hit that rolls 14+ damage will knock you back two or more tiles, which such strong attacks are possessed by several enemies.

I suggest not basing knockback distance on damage so that son of a bitch doesn't increase knockback. This is a nerf to son of a bitch, which is very powerful. You could add increased knockback to the reloader trait, which would synergize well with the shotgun and rocket focus, though you might need to change the name of the trait.

I'm going to strongly disagree with this. Aside from knockback being tied to an attack's strength being intuitive and how it works in actual Doom, this would be a huge fundamental mechanic change that goes beyond just player balancing (now how would you determine knockback from enemy attacks if it's no longer tied to damage?). Son of a Bitch is additionally not so strong that it merits any nerfs, not to mention it being able to increase knockback can already be a drawback (notably having high amounts of SoB resulting in rapid-fire weapons knocking enemies out of vision and so your subsequent shots miss the now out-of-sight enemy), and Reloader already got a substantial buff in 0.9.9.8 by having its effect be improved to -30% reloading time per level (while shotguns also don't need any farther buffs when they were already the most reliable weapon type before the aforementioned Reloader buff gave them a complete cakewalk of an early game). On top of that, not tying knockback to damage would be a crippling nerf to Pistols that heavily depend on reaching the damage thresholds to cause knockback to stay out of an enemy's vision and kill enemies before they reach them, and Pistols are already easily the weakest builds in the game.

Maybe a guaranteed combat pistol somewhere would be nice, like in Phobos lab.

This would be very strong for Pistol builds and worthless for every other build; special level rewards should avoid only benefiting a small amount of builds, the guaranteed Combat Shotgun is a far better reward in Phobos Lab and Military Base (being an invaluable utility weapon for every build in the game and not just benefiting Shotgun builds). Additionally, the suggestion for a new stronger common Pistol already does cover Pistol builds being handicapped by the lack of a guaranteed upgrade (first point in the equipment section of the New Content post).

UI change: When using look mode, the screen should scroll if you try to look near the edge of the screen. I'm not sure if there's a way to scroll the screen without using the mouse, but I don't like using the mouse to check around the map.

I use mouse and so never use the look command, but I certainly see how this is annoying and an outright gameplay detriment for keyboard-only players in graphic mode, so this is a no-brainer fix. Will add it to the OP.

I suppose there is no harm though in adding it as a toggle in the legacy settings if people really want it back though (assuming there is no coding complications with it).

This would be a nightmare to sensibly support alongside keybinding rebindings unfortunately, that's why I removed it.

[Omega Tyrant]

This would be a nightmare to sensibly support alongside keybinding rebindings unfortunately, that's why I removed it.

Noted, supporting rebinding keys is definitely more important in that case than maintaining support for legacy item selection.

[Buzzard]

Wording Change:

Currently, Ironman specifically states it gives you 20% more health points when in fact it gives you a flat 10 regardless of what class you are. If you were a Marine, 20% of your starting health would be 12 more hit points. I understand that this is partly due to how Angel of Humanity works, but Angel of Humanity already tells you that Ironman only gives you +2 more health points. In addition, Marine itself says you get 10 more health points instead of a percentage increase.

I would reword Ironman to just state that it grants you 10 more health points (just like how choosing Marine does now) and just keep the wording on Angel of Humanity where it says that Ironman grants you +2 HP now. I would also probably add in that Marines do start with 12 on AOH on the AOH trial selection screen, just to be clear.

[Omega Tyrant]

Updated the OP, as well as got a few new suggestions:

*Buff the Chaingun's accuracy to +3

The Chaingun is in an awkward spot compared to the other standard weapons, where it not only has a better standard weapon of the same type that completely outclasses it (the Plasma Rifle, after which being obtained, rapid fire builds will only keep the Chaingun around for ammo conservation purposes), but it is also a rather lousy weapon in the early game without several cumulative levels of EE + SoB or playing in Angel of Max Carnage, with its very unreliable damage output (especially against high armor enemies like Pinkies and enemies with bullet resistance like Lost Souls, where half the time a bullet from a Chaingun will only do 1 damage to them without SoB). Even when playing rapid fire builds, I find myself still mostly using Shotguns until I get a Plasma Rifle because the Chaingun is so unreliable (especially with Ammochain, where you're blocked Eagle Eye and so can't hit anything with the Chaingun), and if I'm not playing a rapid fire build, I basically never bother with a Chaingun (with its only possible niche for them is when playing Nightmare or Angel of Darkness, being a means that is slightly better than the Pistol to kill enemies without knockback so they die exactly in a spot that destroys their corpse). The Gatling Gun assembly exists to give a big early improvement to the Chaingun, but you typically won't get the two Bulk mods to make it until you clear Phobos Lab/Military Base, by which point you likely have a Plasma Rifle or will get one very soon, and so you likely rather save them for Fireproof armor, buffing the Chainsaw, making a Tactical Rocket Launcher, or possibly building a Nanomachic weapon.

Buffing standard equipment is tricky, as they're so integral to how the game been balanced since its inception and a buff to them that is a little too much can upend that balance, but I would like to see the Chaingun get some help and there is room to improve it. So I propose PowerPlayer's/Buzzard's idea to slightly buff the Chaingun by increasing its base accuracy to +3; this gives it a bit more crucial reliability so burst builds will actually use it more and non-burst builds may find it a bit less frustrating to try using, as well as gives it something over the Plasma Rifle rather than just using a cheaper ammo source. I think you could increase its accuracy to +4 instead or its damage to 1d7 too without shaking things up too much, but again given how delicate the balancing of standard equipment is, I rather err on the side of caution with buffing them. This change would also indirectly buff Former Captains, but since they are usually such a nonthreatening enemy (with Sergeants even often being more threatening despite the Captains having the higher danger rating), them getting buffed would be fine.

*Have Sniper mods reduce the dropoff reduction penalty on Shotguns.

Currently you can apply Sniper mods to Shotguns, but like Agility mods, it does nothing. There is the Plasmatic Shotgun assembly so Sniper mods can do something for Shotguns, but this isn't an assembly you'll necessarily want to make (especially if you're not playing Nightmare or Angel of Darkness for its corpse disposing abilities), as Shotguns can be buffed a lot more through conventional modding and not lose the ability to corner shoot with them (as turning it Plasmatic would). This makes Sniper mods a pretty lousy find for Shotgun builds much of the time, and gives no worth finding multiples of them (woe behold the Shotgun build whose "reward" from Deimos Lab is two Sniper mods), farther enforcing Sniper mods being the least useful rare mod by far.

Considering that, Sniper mods should do something directly on Shotguns rather than nothing, and an obvious idea that comes to mind is to have Sniper mods improve their long distance damage by reducing the Shotgun's dropoff reduction rate by 1% per applied Sniper mod. This makes Sniper mods always valuable in a unique way for Shotguns, whether you're a Shotgun build or not, and gives more interesting modding ideas for Shotguns so that going PPPTT or PPTTT isn't the only optimal modding endgame for them, while not necessarily being broken either even if you triple Sniper mod a Shotgun (as even a Combat, Assault, and Plasma Shotgun couldn't have their dropoff reduction rate fall below 2% per tile, so they would still see some damage reduction at very far ranges).

*Add new Unique boots: Dimensional Boots (or any other more interesting name)

Currently we only have two Uniques in the games that are boots; the Enviroboots and Nyarlaptotep's Boots. This is for good reason, as you are limited in interesting things you can do with boots, and the existing special boots already cover strong fluid protection (Acid-proof Boots, Gothic Boots, and the aforementioned Enviroboots), faster movement (Phaseshift Boots), and both (the aforementioned Laptop Boots), but we could have one more to have a bit more variety with the available Unique boots. When thinking of interesting effects new boots could have to merit putting them into the game, one idea that came to mind is boots that let you move two spaces for each action, which has the following unique applications:

*You would now have a means to actually dodge Revenant missiles, as well as dodge Archvile zaps within their vision.
*You have a means to avoid fluid damage without outright fluid immunity over 1 tile wide fluid rivers/pools, and otherwise can farther limit fluid damage without needing big fluid resistances, by effectively having to move through half the fluid tiles.
*You can get more usage from action-based powerups, as you'll cover more ground in less actions (especially useful when you can't rocket jump for whatever reason).
*Has a drawback in that only moving two tiles at a time gives you less precise control, while switching to another pair of boots takes time. Can also come with a big movespeed penalty so that you're not moving across maps absurdly fast.

I'm unsure of what to name them, but "Dimensional Boots" comes to mind if no one can think of something better. Exact stats also need to be hammered out if this idea is doable and accepted, but I have the following stats in mind:

Protection: 4
Resistances: None
Durability: 100%
Move Speed: -30%
Knockback: +30%
Depth: 12+
Weight: 2

I think the problem with Entrenchment isn't that Entrenchment is bad, but that chain fire is bad. Chain fire should be changed, then Entrenchment can be reëvaluated. Right now, I only use Chain fire to save ammo. I suggest removing the 2/3 fire speed shots penalty from the first turn (so you fire full shots from the start), and make chain fire the default firing mode. Then make burst fire as an alternative fire which fires 2/3 shots and cancels any current wind-up. This is a buff to chaingun (which kinda needs the buff, imho). It's only a slight buff to plasma gun since we are usually more concerned with ammo efficiency than raw output on plasma gun. Hyperblaster might need nerfing though if this goes through.

I'm wondering how OP Entrenchment would be if it gave you defense any time you take any action except for moving. Maybe the defense could build up based on the time spent standing still. Or, to keep it attached to rapid fire weapons, the defense could scale with amount of chain fire wind-up.

[TNT]

Related to Chain-Fire, Entrenchment could remove the current limit of 3/2 number of shots after the third turn. Just how far the number would go may need to be tested.

I suppose it could be done as just a general buff to chainfiring even outside of Entrenchment as Khashishi suggests

Maybe you could buff Chainfiring, but turning it to the default fire would definitely be a no-go. One problem with chainfiring is how when switching targets, your fire "pans" over and several shots get wasted in the process, weakening your damage output and wasting ammo, so even if you buffed it so it started at a normal fire rate, it would be a nerf to rapid fire weapons when you can no longer switch targets so smoothly and when built up rapid fire weapons will often kill enemies in one normal burst anyway.

The other problem with Entrenchment, having actually used it in 100% UV runs in the standard game and A100, is that actually trying to take advantage of it will result in your clip running out fast and now you're stuck having to reload with no extra resistances (a problem that becomes even more severe if you have Chainfire deplete your ammo even faster), unless you find a Minigun and bulk mod the crap out of it (while hoping enough Chaingunners spawn to support your 600 bullets a minute diet), or you're lucky enough to find a Nano mod and make a Nanomachic Plasma or Laser Rifle, both requiring lots of luck. Speaking of the Laser Rifle, yet another serious issue with Entrenchment is that it also requires several auxiliary traits to function effectively, as unless you find a Laser Rifle, you practically need Eagle Eye to effectively use rapid fires and preferably at least two levels (unless you got a mastery like Ammochain that can get away with it by affording the ammo cost of the more dakka route), while also really needing Whizkid (without a Nano mod, you're gonna need several bulk mods so you can actually chain fire more than a few bursts, and with a Nano mod, you're gonna need WK2 in order to build a Nanomachic weapon), and then there is still all the good stuff to invest into, all for one of the weakest mastery effects in the game. If a mastery is going to require significant secondary investment, it's gotta be actually worth it (like Gunrunner needs Shottyman and Whizkid, but it can be somewhat worth it as it offers one of the highest potential ceilings in the game).

[Buzzard]

Nightmare! currently does not show you the 10% speed debuff that is applied to all classes. It should probably be noted in the player statistics to ensure that people don't get confused about why they are getting double-moved on.

[TNT]

Fair enough on the ammo problem. Given that after a lot of firing, chainguns are super hot and keep on spinning a bit, maybe you could have the resistances last a couple of turns after you stop the chain fire be it voluntarily or if you ran out of ammo midway

I remember on the server we brought up maybe having it auto-reload which could be good/nice to also have but is also gated by having ammo - that can't really be addressed without something ultra drastic like ammo-chain sadly. You could try and move slightly in that direction by having so that while chain firing, you require less ammo to fully reload. Assuming that's doable you could even tie it to how many turns you've spent on chain fire.

[Buzzard]

Scavenger mastery text needs to be updated to state that you can also scavenge boots and armor now.

Got a bunch of new suggestions for badges and medals:

*Allow the Gargulec Medal to be obtained alongside Gargulec Cross

It was changed so that you could obtained lesser versions of medals alongside their greater versions if you haven't obtained them already, but as I found out when doing a 100% UV AoB run, you still cannot obtain Gargulec Medal alongside Gargulec Cross. If you've proven you can get 100% kills in AoB on UV or N!, you shouldn't be forced to do another 100% AoB run on a lower difficulty to get both medals.

*Add a new medal for defeating John Carmack without getting damaged

We have the Cyberdemon's Head and Mastermind's Brain for no damaging those respective bosses, and even Shambler's Head for beating Hell's Amory/Deimos Lab without damage, so why not an equivalent medal for the true final boss? I'm unsure for the name though, maybe "Keen's Helmet"?

*Add a new medal for completing a Conqueror run in any of the following challenges: Angel of Red Alert, Darkness, Impatience, Purity, and Masochism (while also requiring it to be a pure challenge, so it can't be cheesed by doing a dual angel with AoMC)

Seeing how Thomas' Medal exists for doing a Conqueror in Angel Of Humanity, I think we should also have a medal to acknowledge the achievement of doing Conqueror runs in these challenges where it's arguably as hard or even harder to complete a Conqueror run in (seeing how rarely they all been done, with me having firsts in two of them (AoI + AoD), a first in the pure challenge on UV for another (AoMs), and a second in one more of them (AoRA)). You could have one medal encompassing them all, or individual medals for each challenge. The potential name has to be discussed.

*Change Longinus Platinum to beating Unholy Cathedral without Brute on any difficulty, while also excluding Angel of Max Carnage and Angel of Light Travel from being able to earn it and Longinus Diamond

Current Longinus Platinum is just a check on if you can play Nightmare. You're able to play Nightmare well enough to make it to Unholy Cathedral? Then here's a free platinum for you, when any melee build will run through the Cathedral all the same regardless of difficulty, making it a very plain badge with no interesting challenge to it. Considering that beating Cathedral without Brute requires some ingenuity or particular technical play regardless of difficulty, it should be rewarded on difficulties below Nightmare. If you really don't want this badge being winnable on HNTR, then restrict it to HMP or at least UV. Current Longinus Diamond can stay as is, as beating the Cathedral on Nightmare without Brute does add some more depth to it (as the 10% speed penalty complicates speed-based strategies, and resurrecting complicates trying to utilize the Hatred Skull). I also want to propose disallowing Angel of Max Carnage and Angel of Light Travel from this badge, as they make it much easier, and apply the same restriction to Longinus Diamond as well.

*Add a new set of badges for The Chained Court

I find it weird how only a few special levels have complete badge sets related to them and some having no badges at all, so I think that should be rectified. The Chained Court is especially conspicuously absent with its complete lack of awards for it, given how it's one of the more iconic special levels and has a harder version that is ripe for challenges. As such, I propose the following badges for it:

Unchained Bronze: Clear The Chained Court after clearing Hell's Arena.
Unchained Silver: Clear The Chained Court after clearing Hell's Arena on HMP.
Unchained Gold: Clear The Chained Court after clearing Hell's Arena on UV in Angel of Shotgunnery (Shotguns have quite a bit more trouble here given the lack of good corner shooting spots and the inability to slug it out with the Barons and Arena Master from far range, but not too much more difficult as to merit beyond Gold).
Unchained Platinum: Clear The Chained Court after clearing Hell's Arena on UV in Angel of Impatience or Angel of Masochism (you got the berserks that can be easily destroyed by the Barons or Arena Master, or one Supercharge if you can get a well timed level up, making that all the healing you get, and you gotta do the annoying task of clearing Hell's Arena in AoI/AoMs first to even get an attempt).
Unchained Diamond: Clear The Chained Court after clearing Hell's Arena on N! in Angel of Purity (good usage of the Berserks is critical to beating the Unchained Court, especially on Nightmare, so having only the single berserk from the Chainsaw to work with should make this a worthy Diamond challenge, not to mention you have to beat Hell's Arena on Nightmare for every attempt, likely burning a lot of medkits in doing so).
Unchained Angelic: Clear The Chained Court after clearing Hell's Arena on N! in AoSh + AoP (essentially combining both the Gold and Diamond challenges together, not to mention on AoSh you're going to have a lot more complications with destroying the Baron corpses that will revive without the Arena Master's help, you really better make that Chainsaw berserk count).

*Add a new set of badges for Phobos Lab and Military Base

Phobos Lab and Military Base lacking any badges is more understandable as they arrived in 0.9.9.7, but they're still ripe for interesting badge challenges with them and so should have a set. They could have their own distinct set of badges given they're completely different levels, but I think they can work with a shared set to simplify things, so I propose the following (naming the badges after John Romero since he created both of these original Doom maps and currently he is conspicuously missing from any references in the game):

Romero Bronze: Clear Phobos Lab or Military Base on HNTR.
Romero Silver: Clear Phobos Lab or Military Base on UV (gotta at least deal with the Nightmare Demons or the full Elite Former squad for the Silver).
Romero Gold: Clear Military Base on UV in Angel of Impatience (thus you must clear it without being able to manipulate the Elite Formers to favorable positions with gift dropping, and camping the start will leave you with no means to heal).
Romero Platinum: Clear Phobos Lab on UV in Angel of Marksmanship without Sharpshooter (getting Sharpshooter allows you to reliably knockback the Nightmare Demons and thus makes an otherwise brutal challenge a lot more manageable, so it should be disallowed, but it would still be fine enough to implement without any trait restriction).
Romero Diamond: Clear Phobos Lab or Military Base on UV in Angel of Red Alert (while extremely extremely difficult, I think this can be doable without Angelic tier luck if you specifically gear your build all towards it).
Romero Angelic: Clear Phobos Lab or Military Base on N! in Angel of Red Alert (this one I'm not sure is even possible, but the extra level or two and extended powerup duration you get in Nightmare could make it barely doable with lots of rockets for gibbing + rocket jumping).

*Add a new set of badges for Hell's Armory and Deimos Lab

Another special level pair that weirdly lack a badge set, only having two basic medals, and again they very much make for good challenges. As such, I propose the following badges:

Quake Bronze: Enter Hell's Armory or Deimos Lab and leave without releasing the Shambler(s) (Avoiding making it the same as the Hell Armorer medal).
Quake Silver: Clear Hell's Armory or Deimos Lab on HMP
Quake Gold: Clear Hell's Armory or Deimos Lab on UV in Angel of Confidence (thus clearing them with only a couple levels and minimal equipment, but given the ease at which you can grind runs for this, it shouldn't be higher than Gold).
Quake Platinum: Clear Deimos Lab on UV in Angel of Masochism or Angel of Humanity without Berserker (thus you must beat the dual Shamblers without being able to heal nor activate run more than once, or in a challenge where even with ideal armor you can't take more than a few hits inbetween medkits, and without Berserker being able to greatly increase your durability against them, while also excluding Hell's Armory as it is too much easier to be an appropriate Platinum challenge).
Quake Diamond: Clear Deimos Lab on UV without taking damage, excluding the Angel of Max Carnage and Angel of Light Travel challenges (beating the dual Shamblers without getting hit is so hard that the devs didn't even bother programming in any extra reward for doing it like with Hell's Armory, so it should be worth a Diamond badge without playing Nightmare, just disallow AoMC and AoLT from getting this badge since they will make this badge much easier).
Quake Angelic: I'm not sure, perhaps clear Deimos Lab on N! without taking damage in Angel of Berserk, Angel of Marksmanship, or Angel of Shotgunnery (aside from the extra HP the Shamblers will have and the 10% speed penalty complicating manners, the weapon locked challenges will also complicate disposing of the Shamblers' corpses without lucky equipment finds, making it more distinct than just "same as Quake Diamond but a bit harder").

The Brick, Skull, Spider, and Lava series could be completed as well, and Halls of Carnage could use a badge set too, but I'll leave those free for anyone else to suggest new badges for them.

*In House Of Pain, seal off the Large Health Globes behind walls/doors that require the Arena Master's Staff to open

After very thorough playing with House Of Pain, I find it is still a bit too easy. While I think the Demons could still be replaced with their Nightmare version on UV/N!, the big culprit for the lacking difficulty is the four Large Health Globes, that means I almost never need to expend any medkits on this level. Additionally, saving the Arena Master's Staff for House Of Pain isn't rewarding enough on this level (in the beta testing when The Vaults was disabled, I never bothered bringing the Staff along since it didn't make a meaningful difference, and in official 0.9.9.8 I often forget the Staff is even an option for this level, if I just don't ditch it once I see House of Pain spawned instead of The Vaults). As such, I want to propose requiring the Staff to access the Health Globes, so this level is a lot more likely to burn your resources without the Staff, thus more encouraging you to bring and use the Staff here.

*Increase the Blaster's generation weight to 4

The Blaster currently has a generation weight of 2, which makes it as rare as most uniques. The Blaster is certainly very good, it's arguably the best thing a Pistol build can find, but it's not so good as to be made as rare as a Nuclear BFG, especially when it's still near worthless for any non-Pistol build. Increasing its generation weight to 4 would be more appropriate, and this would make it equivalent to a Nuclear Plasma Rifle, a similar innate nano weapon that has more utility for builds beyond those specializing in its weapon type.

*Have the Ballistic Armor assembly retain plasma and acid resistances from its base


The Ballistic Armor did get a nice buff in 0.9.9.8, but something I noticed that I didn't before is that if the base armor has any plasma or acid resistances, they'll be removed entirely when used for this assembly. The -20% fire resistance is already a harsh enough drawback, removing other energy resistances is just excessive, and in particular makes using Blue Armor very bad for this assembly. This also isn't inline with Fireproof Armor, which retains the base armor's other resistances.

*Have Grappling Boots retain the base boots' movement speed instead of being -10%

Grappling Boots is one of the least used assemblies in the game. There is a theoretical niche for it with melee builds that are getting annoyed by too much by knockback, for Invulnerable stair diving if VMR are knocking you around too much as you try to get to the stairs or for anyone that's really paranoid about getting knocked back into lava. But any such non-Invuln use for it is killed by the -10% movement speed, and the set -10% movement speed also means if someone dislikes the knockback boost of Phaseshift Boots, they can't use this assembly on it to get knockback resistance + increased movement speed. Grappling Boots would still rarely be made if they retained the base boots' speed, but if they didn't slow you down, there could be instances where you would consider it.

[Omega Tyrant]

For another potential hotfix for bugs and other issues, here is how I would prioritize the listed bugs and other issues based on how urgent I think they are:

Critical priority
*The trait selection lockup bug. (Uncommon but game-ending when it happens, with no way to salvage your game nor even a mortem in that state, but no apparent cause has yet been identified)

High priority
*Lightfoot Diamond and Angelic badges aren't being awarded when their requirements are fulfilled. (This is likely being caused by indirect kills being erroneously categorized as "melee" kills, which would effectively make these badges impossible to get)
*Dragonslayer doesn't grant any amount of berserk. (Aside from this notorious weapon's signature mechanic not working, this is a potential run ender if picked up by a build without Berserker or Malicious Blades, as you need to be berserked or have Malicious Blades' defensive boosts to survive being locked to a melee-only weapon)
*Halls Of Carnage's lava flood sometimes doesn't activate, allowing you to play the level at whatever pace you desire. (A beneficial bug, but aside from making a special level much easier than intended, this bug seems to occur at random and so it cannot be anticipated if any given run will benefit from this bug or not)
*You can easily softlock in House Of Pain on Nightmare and in Angel Of Darkness if you don't have the Arena Master's Staff, from an enemy reviving in an earlier room while you're locked in a later room. (While there are a couple other special level softlocks, this one stands out as it doesn't require an unwise Phase Device use, but it may not have an easy quick fix that would make this eligible for a hotfix, ideas on how to address it are in the special level section of the OP)

Mid priority
*A Technical mod's resistance boosts on armors/boots get carried over in assemblies that uses a Technical mod, as long as the mod isn't applied last to finish the assembly. (A beneficial bug, but it does make several assemblies better than they're supposed to be)
*Corpses can sometimes be ungibbable by explosions and plasma(tic) shotguns. (I see it frequently happen in House Of Pain's first room, where a Pinky corpse or two will just refuse to gib, but it's unclear what is causing it and that is not the only level it can happen)
*Brute's accuracy bonus is still not being applied properly to thrown knives/Mjollnir.
*When using the look command, you are unable to scroll the screen with your keyboard, preventing keyboard-only players in graphic mode from seeing the whole floor.
*Direct explosive hits seem to have their damage calculation occur after knockback, making them weaker than they should be or even deal no damage at all. (Would list this as high priority but it's a long-standing bug from prior versions and so may not have a simple fix)
 
Low priority
*Sharpshooter's effect doesn't work with the Demolition Pistol and (presumably) the Anti-Freak Jackal. (Could arguably be mid priority, but the affected weapons are rare and Sharpshooter isn't hurt that much by it, so it can be set aside for the next full version if it's not a simple fix)
*When rocket jumping, your targeting cursor can extend beyond immediate adjacent tiles, despite not being able to target any tile beyond that range. Previous versions would just lock its targeting to its valid range, which made rocket jumping around quicker to input. (As a heavy rocket jump user that is very annoyed by this bug, my personal bias wants to label this as mid priority, but it ultimately has little gameplay impact)
*Projectiles can occasionally clip through walls at weird angles, including explosive projectiles going through outer boundary walls without exploding. (Could be quite exploitable in the right circumstances, but happens rarely enough and is usually not impactful enough to be an urgent bug. Needs more testing to determine what causes it, I seen it happen in House Of Pain's first room a couple times in particular but seen it in random floors too)
*Ammo stacks dropped by ammo dispensing lever aren't affected by the difficulty multiplier. (Not sure if this is an actual bug or intended, but it's a minor issue either way)
*In floors beyond level 30 in A100/666, you still predominantly only see lava instead of a greater variety in fluid generation. (Not sure if an actual bug or if the new level 30+ fluid generation formula just has a very heavy bias towards lava, but either way you're not seeing greater fluid variety in deep A100)
*When the Apostle spawns on the final floor of A100/666, it and all enemies that revive/get spawned will be immediately revealed by the enemy reveal mechanic since technically everything dies when you first enter the floor, despite this being a boss fight. (Could arguably be mid or even high priority, but labelling as low priority since very very few people will actually encounter this and since the Apostle hasn't gotten its planned buffs yet that could make it an actually compelling boss fight).
*House Of Pain doesn't have a default song defined in the music.lua file, so it'll play a random song unless you add a proper entry for it in the music.lua file yourself.
*Various UI issues that don't affect gameplay. (see the OP for all that been compiled so far)

[Omega Tyrant]

With the release of the first 0.9.9.9 beta, I'm gathering new bugs and other fixes to make regarding it here:

*Screenshots aren't being saved, unless you manually create a folder named "screenshot" in DRL's root folder

Self-explanatory, screenshots aren't saving without the aforementioned manual fix. With this version shaking up the folder structure, and moving the screenshot folder into the "drl" subfolder of the "user" folder, it simply seems the screenshot function hasn't been updated to account for the new folder setup.

*Nightmare's -10% speed penalty may not be working

So before, one of the errors listed was the player info screen not reflecting Nightmare's -10% speed penalty, but after playing Nightmare, it never seemed like I was any slower than usual, and after getting a setup to test with a Cacodemon while I was a Marine wearing equipment that neither sped me up nor slowed me down, I can confirm no speed penalty is applying (as the Cacodemon never got a double move, which it should about every 10 movements if the speed penalty was working).

After farther testing with previous versions back to 0.9.9.6 and Kornel stating he has no recollection of ever adding this "feature", it turns out it may not have actually existed in the first place (or if it did, it was silently removed back in a very old version prior to 0.9.9.6). Kornel also stated he doesn't like the idea of adding difficulty by nerfing the player, so we can probably expect it to never get (re)added to the game. However, there is the question on if enemies could get a universal +10% speed bonus instead (it has a similar effect to the speed penalty but the player won't be given a harder time on any time-sensitive event like a timed nuke level and dealing with N!'s respawning that becomes more frequent the longer the player is on the floor). It would have probably been overkill on old Nightmare that a lot of people found too difficult/unfun even with it lacking the supposed speed penalty, but with the new N! changes making respawns easier to manage and no longer needing to fuss with corpse disposal for kill %, it could be added as a farther means to spruce up N! (as well as assuage any potential complaints from returning players of the changes making N! too easy), and farther replicate the "fast monsters" aspect of actual Doom's N! difficulty (my concern though would be that it could make some barely possible badges like Everyman Angelic veer into the realm of borderline impossibility, either way this should get some discussion).

*Item reveal is not working in Nightmare. Have it activate when all active enemies are dead, or after all unique enemies have been killed once.

The enemy reveal mechanic works as it's supposed to in Nightmare (triggering when there's 3 or less active enemies alive on the floor at once), but item reveal isn't activating, even if everything is dead and you destroy every corpse. Having it activate when you have everything dead at the same time, or after all unique enemies have been killed once, will work.

*The game may crash if you attempt to use the Dragonslayer's altfire, Whirlwind.

When testing the Dragonslayer, the good news is I can confirm the permanent berserk effect now works as it's supposed to. The bad news is, we got yet another game-breaking bug with it, this time the game will get a fatal error if you attempt to use Whirlwind. After reloading saves and testing it some, the bug is not consistent and Whirlwind will sometimes work as it's supposed to, while sometimes it crashes with said fatal error, so I'm unsure what's causing it.

*Technician Gold badge wasn't awarded on the run that fulfilled its condition, and was instead awarded at the end of the immediate next run.

A weird little bug I noticed; after copying over player data I used in prior betas, I did some quick test runs to knock out some more assemblies, so I don't get any Schematics when testing Nightmare, and in the process I finished all the basic assemblies, which should give Technician Gold. However, in the run I did so, I was not awarded Technician Gold, and it was instead awarded in the immediate next run after where I died before I could even make any assemblies. The linked Discord mortems show it, but for additional info, the Power Armor assembly was the last Basic Assembly needed, and in the run I got both the Schematics for it from Armory and created Power Armor immediately after before leaving Armory, so maybe that caused this bug?

*The Mortem's kill ratio message seems to be based on the total enemy kill ratio with respawns factored, rather than the unique enemy kill ratio.

Self-explanatory, so for example if you kill every unique enemy at least once and thus fulfill 100% kills but leave any respawns alive, you won't get the "This ass-kicking marine killed all of them!" message. Badges and medals that have a requisite kill ratio are being properly awarded based on the unique enemy kill count however, so a minor bug.

*If you fulfill the clear condition for a special level (typically having every enemy spawn activated and having everything dead at once) and then leave with any respawns alive, the game will give you the level clear message in the exit text and the Mortem, as well as any badges/medals that require clearing the level, but the level will not be counted as completed for Conqueror.

Another weird bug noticed; I thought with the change to how the enemy kill count works regarding respawns, you could now have special levels be considered complete after fulfilling their complete condition without having to make sure no respawns are up when exiting. If you do complete a level and then exit with any respawns alive, you get some weird half-state of completion; the level's exit text and the Mortem's level history text will be what you get for completing the level (e.g. for The Vaults, the Mortem states "He cracked the Vaults and cleared them out!" rather than "He managed to scavenge a part of the Vaults' treasures.", as seen in this mortem), and after testing, I can confirm you still get any badges/medals tied to completing the level (as seen in this mortem, where I still got the Grim Reaper's Pin and Reaper Diamond badge after leaving Limbo with respawns alive), but the level won't be counted as actually completed in the special level count section, so you won't get the Conqueror medal and (presumably) any badges that require achieving a Conqueror run.

*Modding display menu sometimes has inaccurate info.

The new modding display menu is a good addition to inform players what they're actually doing with any mod, but I noticed a couple issues. The first is when applying a bulk mod to armor and (presumably) boots, the display will show the bulk mod making said armor/boots 10% faster when it's the other way around (when applied however, the bulk mod still works as it's supposed to with making your armor/boots -10% slower). The second is when making an assembly like Tactical Boots or the Ripper that requires a second mod of the same type that you normally can't apply, the modding display will show the added effect of the second mod despite being unable to apply it without making the assembly (for example, if assembling Tactical Boots, the effect section will display your Steel Boots going from +10% to +20% speed).

*The game will not allow you to attempt applying Firestorm and Sniper mods to non-compatible equipment, notably preventing you from assembling Demolition Ammo.

Self-explanatory, this issue would also prevent being able to make any future assemblies that require adding a Firestorm or Sniper mod to non-compatible equipment (such as the proposed Scouting and Blastproof Armors).

*If too many sounds play in quick succession, the music will be turned off.

When employing the usual camping strats on Military Base, I noticed the music stopped playing. I saved and reloaded, which got the music playing again, but then I spammed some more run -> wait while nearby all the formers in the locked room and indeed that knocked out the music again. So it seems the cause is simply having too many sounds play at once, which can happen when spamming run -> wait near a group of enemies that can't reach you. The aforementioned saving and reloading restores the music, as does entering the next floor.

*Add ammo pickups to The Mortuary (and possibly Limbo depending on future changes to it).

A major mechanical change that was tested out is respawns no longer dropping any weapons and ammo they inherently have, both enemies revived by Nightmare/Angel of Darkness and by Archviles. With the other major respawn changes (corpses in your vision don't revive in Nightmare/AoD, and respawned enemies of either variety don't count towards the kill counter), this appears to be a fair change (100% kills in Nightmare without playing a melee build is very much viable, while you conversely can no longer farm a full inventory of ammo and Plasma Rifles off of any isolated Former, nor cheese Archviles with Formers on any difficulty to get as much ammo as you want). However, the big concern is Mortuary on any difficulty, as before you could rely on all the respawn ammo drops to soften the huge ammo sink the level normally would be, and even then you would still often come out with a significant net negative in ammo. With respawns no longer dropping ammo, you're outright in danger of running out of ammo or otherwise will likely deplete your ammo to a crippling degree, and if playing Nightmare, I don't see Mortuary being even viable without melee investment + strong melee weapon or having a Nano weapon (the Nuclear BFG helps, but aside from being able to easily get destroyed before picking it up, you can't easily recharge it when you got a bunch of enemies bearing down on you and it's not even that strong). To compensate, I think Mortuary should have ammo added, which can be in the form of at least one ammo box in each corner (have 10mm Ammochain in the top left, Power Battery in top right, Rocket Box in bottom right, and Shell Box in bottom left), and then on Nightmare, double the amount of them. As for Limbo, I think it's fine without added ammo, as aside from being significantly easier, you'll typically deplete much less ammo on it due to having less corpses around, much easier corpse disposal with all the lava, and lava saving you ammo on killing things by hitting them into it. However, if the proposed Blood fluid is added, I'm thinking it should replace the lava on Limbo to put it more on par difficulty-wise with Mortuary, and if it's added exactly as proposed (which means it doesn't damage enemies), perhaps Limbo should get some ammo added too just in case (at least an ammo box of each on Nightmare in the same setup as Mortuary).

*In the Nightmare version of The Vaults, the six Red Armors that are supposed to spawn next to the right vault's Barons may be bugged as it appears only one Red Armor is spawning, and the ease at teleporter camping the center vault's Nightmare enemies should be fixed.

As part of 0.9.9.8's big difficulty buff to The Vaults, on Nightmare it has UV's Arachnotrons and Archviles replaced with their Nightmare versions, and was supposed to spawn Red Armor next to the right vault's six Barons, so that they all have very good armor instead of only having one random armor between them. However, the Red Armors' spawning appears bugged or improperly implemented, as each time I played it, I only ever saw a single Red Armor drop from a right vault Baron each time (and it doesn't appear these Red Armors are accidentally spawning anywhere else, as the left vault with Nightmare Arachnotrons has no armors and I'm not seeing a bunch of Red Armors on the center vault's Barons either). Another issue is due to all Nightmare enemies becoming immune to fluids in 0.9.9.8, the newly added N! Arachnotrons and Archviles can walk over the lava blocking the center vault's teleporters and allow them to escape. Now I don't think this is itself a bad thing, it can add quite the scare factor to the level and it can put you in a really bad spot if a N! Arachnotron or Archvile suddenly pops up in a very awkward time across the long thin halls on the level or when you're trying to clear out one of the side vaults, and when going for the Scavenger badges, you still need to get lucky with Phasing into the center vault as the Barons still can't escape it. However, once you realize this and know both teleporters deposit teleportees right next to the stairs, you can simply camp next to the stairs to more safely kill each of the center vault's Nightmare enemies one-at-a-time, and then once they're all dead, you'll have a much easier time clearing out all the vaults. To prevent this, you can replace the lava blocking the teleporters with walls that can be destroyed conventionally, or by tying them to a lever inside the center vault that will destroy them (just make sure the lever is indestructible so it doesn't get destroyed in the inevitable crossfire when a player phases inside). Alternatively, if you want to keep the Nightmare enemies telporting outside of it, change the teleport destinations so the left teleporter's is as it currently is next to the stairs, while the right teleporter's drops you off on the opposite of the map; this would still allow you to spawn camp some of them (or maybe even all if you're lucky), but some others (or even most if unlucky) will evade the spawn camping and trying such can put you in a very dangerous position if one pops up in an unwanted direction while trying to kill another that just teleported in. I'm ok with either solution; the former makes opening the center vault and phasing into it a ton more dangerous, but the latter makes general exploring of the level paranoia-inducing and can be really evil with its potential to pinsir you between some of the nastiest enemies in the game.

*When using the Dragonslayer/Berserker Set in special levels, make killing the Nightmare Demons/Cacodemons not required for completion.

So to access the super secret Apostle fight, you're supposed to make it to Hell Fortress with the Berserker Set on, which you can find randomly if you're very very lucky, but are intended to fulfill the conditions on Nightmare to get them the guaranteed way. Getting the Dragonslayer works fine enough, but then to get the guaranteed Berserker Armor from Mortuary/Limbo, you have to use the Dragonslayer. Prior to 0.9.9.8, this was very difficult, as being stuck using the Dragonslayer means you can't use any corpse disposal weapon and the Dragonslayer itself can't gib big enemies like the Spear and Scythe since it deals melee damage, but it was doable. 0.9.9.8 however, made it so that just equipping the Dragonslayer now spawns infinite Nightmare Demons, while equipping the Berserker Set spawns infinite Nightmare Cacodemons on top. This is fine on normal floors, but this makes beating Mortuary/Limbo on Nightmare with the Dragonslayer an insane task, as in addition to all the corpses repeatedly reviving, you now got the Nightmare Demons repeatedly spawning, who will also repeatedly revive when killed. When testing I was able to do it... but when playing an AoMC + AoLT game (so I guaranteed one-shot everything and guaranteed gibbed Revenants, Cacos, and Arachnotrons, while having the big speed boost of AoLT both limited damage I took and limited respawns/NDemon spawns), and when having Vampyre (which is near-IDDQD since 0.9.9.8). Even then I got low on health at points, and without AoMC + AoLT, I'm not so sure I could have gotten everything dead at once. I simply don't see beating Mortuary/Limbo on Nightmare with the Dragonslayer being viable with any build except with Vampyre and maybe Blademaster.

The simple fix to this would be to not count the infinitely spawned Nightmare Demons towards the level's completion, that way you won't end up in a state where Nightmare Demons keep spawning/respawning on opposite sides of the map and you're unable to ever get everything dead at once. I would apply this to other special levels too, as it makes completing them much more of a tedious pain (Lava Pits/Erebus could also get out of hand if you get bad luck with the Nightmare Demon spawns, especially since lava doesn't kill them anymore). If it's not possible to program it that way, perhaps the Nightmare Demon/Cacodemon spawning should be disabled on special levels, or if that isn't possible either, then maybe just cap their spawning at like 50 per floor (on any normal floor you shouldn't be ever facing more than that, and as a bonus it also limits some potential cheese strategies where you abuse the infinite Nightmare Demons to puff up your kill ratio).

*Have screen shaking intensity vary based on the strength of the projectile/explosion

A new toggable feature in 0.9.9.9 is the screen shaking whenever an explosion of any sort happens. I do sorta like it, but it's rather janky in its current implementation, as the screen shake is pretty strong and seems to always play at the same intensity, regardless of if it's a 2 damage Imp fireball or a 36 damage rocket. This obviously isn't intuitive, and is rather annoying to see the screen shaking so much when just getting pelted by Imps.

_________________________________________________________

The following aren't specifically fixes to issues with the new beta, but rather just new ideas for 0.9.9.9 in general I had that I haven't proposed here yet, and I thought I may as well get them out now instead of continuing to sit on them until it's too late:

*Have more badges require at least a standard win.

Currently, with any badge that require winning the game, a partial win will still award it, except for the few that explicitly require a full win. Unless you actually care about your run's score, this makes a standard win and partial win nearly functionally identical, when they will result in earning nearly all the same awards (the only exception is any badge/medal that has a damage limit requirement, as nuking yourself can push you beyond the damage limit, while instantly disqualifying you from any that require damageless). This also makes the Mastermind even more of a nonfactor than she usually is, since as long as you make it to her with a nuke, you can just set it off and get whatever badge(s) you were hunting without any worry of dying to her. As for what badges to change in this regard, I think every Gold to Diamond badge that require winning the game should at least require a standard win (if they don't already require a full win), with the obvious exception of Pacifist Gold (since you can only get a partial win unless you get a second nuke + Invuln near Dis and pull off a double nuke on the Mastermind + JC), and I would also leave out the Angelic badges as a bit of reprieve, since they're absurd enough as is (though if you wanted to make them require a standard win too, Pacifist Angelic would need an obvious exception, and I would make an exception for Everyman Angelic too).

*Have dying to John Carmack count as a normal death instead of as a partial win.

Something I always found a bit weird is how dying to Carmack still counts as you winning the game, and aside from that being unintuitive, due to partial wins being nearly identical to standard wins as described prior, this results in the choice to fight Carmack having no real risk to it. Die to Carmack while on a Diamond badge run? No big deal, you'll still be awarded the badge. If the prior change is implemented to make partial wins less rewarding, this would be less of an issue, though I would still make this change.

*Disallow nukes from being activated in Hell Fortress, and consider having any active powerups get turned off when entering Hell Fortress.

When fighting the Apostle most recently, I noticed the game outright doesn't let you activate a nuke when it spawns, and I thought why not have this apply to Carmack too? The Lava Element only having 9 actions of invulnerability is deliberate to prevent you from getting easy double nukes off on the Mastermind + Carmack, but as long as you find an Invulnerability on Floor 23 and can rocket jump, it's trivial to nuke the Mastermind and then make it to Hell Fortress to nuke Carmack in time too with that single Invuln (and if you have the Trigun, it's possible to get a double nuke on both with just the Lava Element). To get a full win, I think you should be required to actually fight and kill Carmack conventionally, rather than rely on getting lucky with a floor 23 Invuln and skip having to fight him altogether. On another note, perhaps have any active powerups get disabled when entering Hell Fortress too, as even without nuking Carmack, you can take a floor 23 Invuln all the way to him and easily kill him without damage, or at least get most of the work done before he is able to actually fight back (the game already tries to enforce a fair fight by punishing you for trying to shoot him from out of vision, so it'll be fitting for him to depower you upon entering).

*Spruce up Hell Fortress' Apostle fight.

So I finally got to experience fighting the Apostle in Hell Fortress... and it was even more disappointing than the A100/666 fight. No unique entrance text to indicate anything is different, just the standard victory text when winning, and there's nothing different about the level itself, so you just fight the Apostle in a big empty room (which also means its resurrecting abilities don't get displayed, as the only other enemies are the Nightmare Demons/Cacodemons spawned by the Berserker set, which the fight should end before enough of them spawn to really get involved). Aside from more flavor with unique entrance and victory text, and the prior proposed buffs to the Apostle itself, a big way I think the fight could be improved is having a ton of corpses spawn in Hell Fortress with the Apostle, so its resurrecting capabilities actually get put to use.

*In The Lava Pits and Mt. Erebus on Nightmare, remove the last remaining Radsuit.

Previously I proposed have difficulty-dependent Radsuits on Lava Pits and Erebus to make them more appropriately difficult on the harder difficulties, which was implemented. When finally playing Nightmare however, I noticed the last Radsuit was not removed. Considering Lava Pits and Erebus see no real difficulty increase on N! as is compared to UV, other than a moderately more durable Lava Elemental, having no Radsuits on the level should be a fair change, especially since Radsuits last longer on N! and you can get more use of that single Radsuit than you could on UV (well Erebus needs way more than that, but even if its difficulty is buffed up elsewhere as I proposed before, I think it should still have the Radsuit removed).

*Allow Firestorm mods to be compatible with explosive weapons that have an explosion radius smaller than 3, having them increase these weapons' explosion radius by +1 instead of the usual +2.

Currently, there's an odd restriction with the Firestorm mod, where explosive weapons with an explosion radius of 1 or 2 cannot be modded with it (with the exception of the Tristar Blaster). This restriction doesn't make any real sense and is completely unintuitive (even Icy mistakenly thought you could apply Firestorm mods to small explosion weapons, as you can see in his guide to the Napalm Launcher here), as well as needlessly farther limits the utility of a rare mod that is already limited in its usage. If there's concern of a Tactical Rocket Launcher/Napalm Launcher having its explosion radius increased from 2 to 4 or a Demolition Pistol having its radius increased from 1 to 3 being too strong, then simply have the Firestorm mod give these weapons only a +1 radius boost rather than +2.

*Let the Lava Element appear as a random drop.

The Lava Element is an item with some potentially interesting applications beyond just serving as a guaranteed means to get a full win, as a source of temporary on-demand Invuln at any time. However, even if not saving it for a full win, you only have it for a single random floor you likely won't have any trouble with and then Dis, while you can never get it in A100 where you'll be much more probable to come across a floor that you would actually want to use it. As such, I think it would be neat if you could get the Lava Element outside of Lava Pits/Erebus as a random drop if you're lucky and get to play with it in more interesting scenarios beyond "set off nuke, pop Lava Element at 2 seconds left". You could give it a spawning weight of 3 or 2, and if you want to make the random drop of it an A100/666 exclusive, then set the spawning depth at 30+ .

*More Angelic badge ideas for existing special level sets

I previously thought up ideas of badge sets for special levels that currently have none, so why not potential ideas for completing the sets that already go up to Diamond?

Reaper Angelic: Clear The Mortuary/Limbo on N! in Angel of Humanity. (This is certainly a lot harder than Reaper Diamond, and gives you a reason to actually play AoH on Nightmare).

Scavenger Angelic: Clear The Vaults by luck on N! in Angel of Light Travel. (I don't think just upping it to Nightmare is enough compared to Scavenger Diamond, so the AoLT stipulation will add even more luck to it as you won't be able to stockpile much Phase Devices nor much rockets for a Napalm Launcher, nevermind the added difficulty of just making it to The Vaults with limited ammo and medkits in your inventory that you're sacrificing to fit Phase Devices and rockets in).

Longinus Angelic: Unsure, perhaps clear Unholy Cathedral on N! without Brute, Finesse, and Hellrunner, while excluding AoMC and AoLT? (Restricting Finesse and Hellrunner means outspeeding strategies will need some very specific equipment, particularly a Ripper or else you'll need to spend hours throwing a knife, or a very very good melee armor or two with a Hatred Skull or lots of medkits, might still be too easy for an Angelic badge but could be ok if the proposed change of adding Nightmare Demons to UC on N! is implemented)

Arena Angelic: I'm unsure of this one too, maybe clear Hell's Arena on Nightmare in Archangel of Humanity? (It is difficult to think of something harder than current Arena Diamond without pushing it into the realm of impossibility or lottery luck, and I'm thinking Archangel of Humanity is the only viable option here; you're not restricted to melee-only, but missing out on those two or three extra traits is very significant and of course you only have 10-14 max HP, I think it could be harder than AoB but shouldn't be impossible with the implemented Nightmare changes)
