Well I took him out solo the other night with my 66 Wizzy. Snarable/Rootable and doesn't summon. I added up all my nuke totals and I did 19400 damage so I "believe" he's actually got about 19k hp's. Common loot for me ( killed him 3 times in a row ) was the Fragile Gauntlets. He cast's a nasty lil DoT called Spider Venom. Don't know the the actual stats on the poison though. Was curable with my wifes 66 Cleric. He does Enrage at low health as mentioned above. Hits for about 250 a pop and hits fairly fast. Hope this info helps you all out some.
