Start strong The very first player, on their very first turn, on the very first stage, should aim for the left-hand side of the bottom Pierce Obstructor, at a 45° angle. If they hit it right, they'll get perfect rebounds and one-shot the entire floor. Everything resses everything Most trash mobs revive most other trash mobs, throughout the whole dungeon. They have relatively low health, though - any unit with roughly 25k Attack (or even less for Dark units) will one-shot any trash mob. On every board, try to clear every trash mob at once before focusing on the boss.
