This was first time win through Ossuary. Butcher himself was like the easiest thing in entire run, but getting through Ossuary L1-L2 took crazy healing item spendings and a couple of phase kits too. Since this is a late publication, I have since then won going through Ossuary a couple more times with no struggle whatsoever, one-shotting the enemies. Both of those had railgun too (a Sharpshooter and another Sniper), last time I realized I don't even need Efficient, as Ossuary, unlike Dante Inferno, doesn't starve you of cell ammo.
Early game was JS chaingun (for lack of JS 7.62 rifle), auto-shotty, mag pistol. Auto-shotty proved stronger than I thought it would be, so shotgun ended being the most used weapon and Europa Ruins would give AV3 amp for it which I never rerolled. But, chaingun was cold-modded (also from Rift), so it was too performing decently, which can't be said about plasma shotty for which I dismanted chaingun on Io L1 (even though it inherited the cold mod).
I was Fated to be Sniper, which at the time I didn't quite recall how to play, but figured it would be easy (Ossuary notwithstanding, cause I never before survived even its L2) and didn't look at build guides. From this and the recent run, however, I infer to ignore the weapon restrictions on Deadly precision early-on, and just take it as a prerequisite for the Sniper mastery but don't bother matching early guns to it if you find better ones that aren't compatible.
In Rift branch, a strongroom netted me a guardian armor, which I kept into Ossuary, and only there replaced with duramesh (at the loss of 10% dodge, and guardian was Onyx by that time, but to me it worked better having more armor past that point). In Rift's special level, I put autocalibration on both chaingun and autoshotgun (the latter which was in the final room), but didn't then have faith in autoshotgun (yet it proved to work all game, except railgun from Io Black Site L3 seemed doing even more damage).
Besides AV3 amp I never rerolled, Europa Ruins gave me ancient trinket (affinity towards poison and burn), which only got replaced late in Io.
On Europa L6 I got nailgun, which spawned with Molten and hence I power-modded it (Hunter 1) for the Cryomancer fight. Nailgun I only used on Cryomancer and bots from Io L1, 40 nails spent, never reloaded.
On Io L1, I dismantled my chaingun that was actually doing well, and replaced it with a plasma shotty, but the latter lagged behind autoshotgun in terms of realibity, and it even seemed behind in power too (because didn't mod it for range, I guess). Shadow Halls required lift repair, whereas there was a "boot the gas" event in Io Black Site, and a "world burn" in Io L6, and so I went Io L2 -> Black Site without keycards. Keycards I did manufacture all (station located by full-clearing Vaults), but BFT I merely shot at live bullseyes and then left behind. Because Io Black Site L3 got me an efficient railgun, I dismantled the underperforming plasma shotty, and put cold mod on railgun. Power mod would not appear on railgun until after I killed Butcher.
While in Black Site, I found that clearing the first level before timer cancels CRI arrival on all Black Site levels. Black Site L2 I did boot up the gas, and Black Site L3 had random Toxic Contamination, which was nice, but I could have ran out of plasma ammo (having prevented CRI interference), good thing Vaults has ammo station. Also, I had to kill those turrets myself in Vaults. At least, I guess, I didn't miss any drop of experience that CRI usually steal.
World burn from Io L6 got me relic with Kerberos' rage, and the branching decisions thus were once more confirmed lucky.
To kill Butcher, I let him walk closer to level down his Delirium, shot him two times, stealthed when he was directly adjacent to me, walked a bit away, and delivered a third fatal shot. The run past that was non-eventful (except me buying ancient salves at Dante stations because Ossuary L1-L2 made be paranoid about running out of health).
