Just finished this on my warlock, 487 ilvl. My god, the adrenaline was pumping on that kill attempt! When I beat him my hands were actually shaking quite a bit. I'm amazed I finished the fight because I could actually feel myself shaking my mouse and keyboard. DEFINITELY my most satisfying kill on this game since I started playing. I'm glad I don't have to do it again, though. I think that fight gave me an ulcer. lol
