This is not alot of info as still playing with event, but what have so far. He is sleeping from 100% to 95% at 95% he comes active. After a while "don't know if its random or time based" he drops agro and goes to a weapon rack and gets a weapon set. When he gets The Axe your tanks have to switch to 2h weapons, when he gets the spears your tank has to use a shield, and when he gets any other weapons your tank has to use an set of duel wield. During even random people get charmed, leave top buff slots open to disspell it. Will try to post more info in the next couple of days.
