Gravewarlord (SK) and I (SK)dueo'd this mission. we cleared second tower and then we pop'd him. we FD split and taged surrounding adds, and pulled him to instance ZI. I was buffed to 17k and 3.2k ac with a 12k mana pool. Also, Gravewarlord has about the same. also, we are 800+ aa's. He took care of the adds and i MT'd. was an easy fight due to the fact the spider kept trying to cast more than Hit. The way we got the instance was had a AFK'r in GH take 3rd slot.
Fought him today on Luclin server... took several tries to take him down...seemed to spawn "an enslaved corpse" (lvl 70...unmezzable, very very resistant to slows....) every 25% in health he lost... at 75%...at 50% ...and again at 25%....also seemed to start the fight with a damage over time spell on the tank...not sure of the name....
