I was losing a match against Waste Wanderer Cardish without worry because I still my Bulwark up when he had lethal on board, only for it to just… not trigger and let me die. The only reason I can think of for this happening is that since I was playing with the anomaly that doubles all damage dealt to heroes, the game just didn’t understand that I was actually taking lethal damage. Very sad way to end a dungeon run.
