I did it last night... i think i actually screamed...
ilvl 484 and close to 100 wipes. Had to use a purification potion otherwise i'd never make that enrage timer.
I lost my pitlord at 3%due to it tanking loads of imps, 2 doomlords and Kan. Popped everything i had and pulled it off with i think 10% hp left.
Never again...
