Impressive for HC on a 70 with that much density and that last 90 too, arcane, thunder or ghosts can end your run pretty easy. I can't go on HC becouse mi internet disconects me from the game and i had died more times than i can count so is a waste of time. Hope to see you pushing 80s on S12.
Why do you have ET instead of a generator? AT already consumes a lot of arcane power, did you equip Ranslor's Folly? In that case you have a pretty good CC.
