I cleared it on legendary, but it took me a few tries. I used a UD soul siphon bg for the first round (equip double hate leech on turn 4) Fire eater/soul siphon second round (surround your shrine with bunnies and kill the boss with helm of chaos'ed vixens) UD/IS bg for stage 3. For some reason in the one but last turn the AI even goes through impervious (didn't matter luckily). what did others use?
