I dont know if anyone has talked about this yet but I have heard a rumor about a spell called Reanimation. This spell allows you to bring back an enemy that you just killed and it will become your minion of destruction. I think that this spell would be cool. Go out and kill a daedric god and bring it back to life and let it reak havock along side you. let me know wat you think.
I guess it's safe to say that at least they won't be as dumb as in morrowind. To refresh your memory - they didn't attack anyone untill he actually did damage to you. So a screaming guy charges at you and they are still determening if they are a threat
