Hi i found bug at Veteran: The Banished Cells - Keeper Voranil (4. boss). If u pull him out of the room, i mean downstair and one more room back then his "balls" just get stuck and he will not summon any mobs so he just do melee atack and one aoe spell, so easy to kill him even 2man. I think he should "evade/reset" when u pull him out of room.
