As a wizard had to do 150k to kill it as it healed itself like 6 times maybe more and 1 timed dispelled my snare. Goodthing i have patient harvest up but took awhile to kill lol.
Note mob can dispell himself and he heals like a SoB once he drops below 50.
necro tactic However he has very slow mana regen. engage take him to 30 % ish hp let him heal himself then fd and let agro clear med up adn re engage. works. He will then be pretty much oom.
