Anyone tried to fight Bael in rook's nest and meet this situation? Bael just stand and doing all those lightning charge, then we can't hurt him. This happen on normal map and the elite Rook's nest as well. Me and my friend keep attacking Bael but we can't hurt him, this takes like 30 minutes and nothing happen.

P.S Bael in Rook's Nest - Elite is wicked, his hp is insane. Took us like 1 hour to kill him lol
