anything considered to powerful to stun cannot be drained, so that means most all named boss type mobs. The spell is pretty much useless at the moment. Can only use it once on a mob and most fights where it would come in handy you cant use it, and if a mob is already disabled you cant use it on them for the damage/heal part.
