Damage Taken From Elements
He combos a lot, walks pretty fast and retargets a lot.
Get a decent level blocker or two (250+ is enough), one healer for each of the blockers and several damage dealers and just kill it with your strongest attacks. Note that knights are not only meatshields and should also attack as they do high amount of damage too. Bronze Amulet is recommended because of the manadrain Jaul does.
