Do you even sleep?
I played way too much DoomRL during the holidays :P.
What I wanna know is how did you get to clevel 18, as rescumming no longer works...O_o
And how do you clear the mort on N! anyway?
I'm not sure about this, but i think the required xp for high levels got lowered since 0.9.8.10. Anyway do notice I visited and cleared everything except AoD and Lava Pits (no envirosuits).
Clearing Mortuary is the same as clearing the Arena. The respawns are extremely random, sometimes you have to kill the same monster 3 times on a row, sometimes 6+ monsters get rezzed together, sometimes hardly anything gets rezzed.
How are respawning enemies handled?
Does a revived enemy count as another enemy for both killing and being left alive?
This. Even if you don't care about chasing the respawns, you'll get 75%+ just by 'clearing' the level.
On a side note, Ammochain is clearly the best trait for UV+... there's barely anything a Plasma Rifle A2 can't handle.
