Ahn'Kahet, last boss:
Herald Volazj
So we all know that this boss casts Insanity, forcing everyone in the party to kill 4 of his party members. I found that usually there are 2 or so crappy dps or maybe a healer that can't keep themselves up during this Insanity but that is no longer a problem now!
What you must do:
Once he starts casting Insanity, every party member, especially the melee, must unequip their weapons. After he has finished casting Insanity and you must kill your party members, simply equip your weapon again and kill them. Your party members will barely do any damage now, casters still reasonable dmg so kill these after the healers.
If you do this, the rogue in your party for example, will attack you with his fists and can't do any special abilities.
Enjoy![]()
