Killed it with Sloth hunters shot, triple shot, precision shot, etc. I killed everything in the area except for it, stood away from it with a vampiric longbow, and slowly killed it. Needling shot when his health was about 25%. It didn't move to attack me, just stood there(of course though, it wasn't in my aggro radius.) --The preceding unsigned comment was added by User:184.108.40.206 (talk).
I don't think it can be interrupted, but I'm not sure (didn't have any mesmer) but I used Skull Crack on it and didn't do anything. :/ even when he was casting a spell.
