I guess I'll do more science, crank the evil biome numbers up and find a nice intersection of multiple evil biomes at some prime area.
Anyway, onto gameplay, anyone managed to survive for a long period of time on an undead-raising evil biome? Are there any limits to what sort of things pop back up to life, like only whole skeletons and so on? Do raised undead eventually leave the map or will they remain there indefinitely? How much time does it take for a body to rise? Is it always the same amount of time? How easy is it to dispatch undead in such a biome, is there enough time to dump them into the magma flow, or an atom compressor?
And the thing that came to mind the most: In an "everything rises as undead" biome, I found someone going on about shell of a mussel coming back to life. Let's say a dwarf gets a mood and picks up a shell in a hellish biome where nothing stays dead. What happens if the shell comes back to life before the artifact is constructed? Or when the dwarf is carrying the shell? Nothing major?
Also, since I assume that the game STILL does that god damn "this animal is huge, IT MEANS IT HAS HUGE BONES AND SKIN" thing when it comes to butchershops and tanners, does this make processing corpses in an undead raising biome impossible since your average butcher/tanner isn't all that fast at their work, or does starting work on a piece of creature that's able to rise(corpse, skin) cause it to not be able to rise?
