Well, I don't know that he did, it just seemed that we got through it fairly easily.
There were a bunch of save or die throws that we succeeded on, lots of damage dealt, but the healer had Heal and DC 29 sanctuary effects on all his mass conjuration (Healing) spells, the party wizard cast maximized empowered Chain Lightning during the surprise round (sudden feats for both), we were hasted, recitation, blessed, I've got a Force bow, we had two tanks with 130/181 HP respectively that regularly do 60 dmg a hit, so we were pretty rocking.
