Ooh! I just had a thought... If we're making it like Nethack, you should be able to eat the corpses! (would make Nightmare easier) and they could grant resistances when you eat them! Imps would give you fire resistance, Barons would give you acid resistance, etc... Eating Former Humans would make you sick (like eating Zombies in Nethack) hmm... come to think of it, for balance purposes, eating any enemy should probably damage you since gaining resistances would otherwise be too powerful. Of course, this is all way off the thread topic, but I'll give this some thought...
