Yeah about 150k hp give or take, easy for an 85 to solo just dont try to take her and all the adds at once with no healer. They tickle but if you get enough of them with no heals it can add up. Best i can tell she's about 16 to 24 hr respawn, can't be more exact but definitly under 24 hrs.
did this mob with my dad (monk/clr/shm/chn/2 mages/necro/wiz) monk tanked, max hit with full defensive and shielding was bout 1250 max hit. but i think the dmg varies.
late reply but there is a little trinket right near where the gate opens up. Thats the piece you are suppose to steal if im not mistaken. The guards see through invis though so if you don't clear them out they will likely tag team ya.
.... and that was only one of the four hits I took in one round from her.
(lvl 72 rng, 785 AA's, 2k+ AC, 12k hp buffed, I'm no rag doll)
Our level 71 paladin tank, who is no slouch, took a severe beating from the huge damage spikes, and I was reduced to a stain on the path once Weaponshield had worn off.
It's a hard encounter for the reward, slot 7 augment(s) meant for level 55 - 65.
The reward was meaningless to us since we just wanted to do a quest to get access and beat the zone for fun.
Hopefully, we're headed back tonight for teh win omgz.
