The three Devourer Disciples, archers, that spawn next to the entrance to the Sacrifices quest entrance have an interesting quirk. It seems you can walk right up to them, wait a moment, and they'll stop attacking. No skill check. No spells. No attack. Just walk up, stare them in the eyes, or knees if you're a halfling, and they'll snap out of their mind-controlled attack-frenzy. I suspect this is a bug and will probably get fixed. I hope not. I think it's pretty cool from a role-playing perspective: You don't HAVE to kill everyone. And these three poor souls found the will power to break The Devourer's mental hold over them. After all, they are villagers that don't really want to kill you.
