I killed him today. Dropped shoes. Hit hime with shackle of bones, partially resisted. Hit him with lev 75 pet (buffed with merc buffs and necro haste) Rise of bones, skelly archer, epic, and started dotting. He ate pet at like 75 - 80 percent or so. Hit me for somewhere in the range of 700's to low 2000's. Cleric merc was worthless to save pet. I mean, completely crap. I even had her on reactive, too. I just nuked him down with lifetaps, and had a few of the more dealy dots running (Dread pyre, ashengate pire, curse of mortality, and sickly mists)
~800 AA's , GoD levelish/eleaborate defiantish geared. Yeah, I suck, but I still killed it. 14000 hps and like 13000 mana or something. I forget exactly what I have, but somewhere around there.
Finished fight at like 45ish mana. It wasn't a nail biter, that's for sure.
Give him time, he wanders out where you kill the first couple of spiders. I'd say fight took ~4 minutes (I guess) and I didn't have any wanderers. If I did, I would've just root parked 'em. Set up was Lifetap, root, Shackle, and rest were dots.
Cleric bot did help a lot after pet died though. (Guess she got her priorities straight when there was only one thing left to heal, HA!) He did one round me for 5 - 6 K.
