He should do a party wide mind control:
What happens is once he mind controls, rather than fight each other players simply walk besides him. More importantly, it brings him completely out of combat and resets him giving him full health and mana, as well as him returning to his path.Incite Chaos: Full party mind control. The party will go free for all, and start randomly killing each other. He will not take part in this fight. Lasts approx 15 seconds. Dumps aggro. The first one is cast about 20 seconds in the fight, then again approximately every 40 seconds during the whole fight.
He then proceeds to spam the ability every time the group comes out of the charm, making the party unable to do anything if they do not kill him before the first charm.
