If ur a melee class then get all up in there between his uh... "cheecks" behind him, two hand ur best sword, jam it in there once, if u see him jump then roll away, if he hits u and u survive, wait untill his next attack, right as he is doing his atrack he has a lil cooldown until the next swing THAT is ur free time to heal. Then basically repeat. Edit: if he does a double swipe then u better get ready to circle around him or perish with the stress infused into u.
