  • Leaving immediately after enemies have spawned gives the player information on the fight, potentially improving decision making.
  • If a Devil RoomDevil Room has a Boss Krampus ingameKrampus fight in it, Isaac may choose not to fight him and leave.
  • If GreedGreed / Super GreedSuper Greed is found in a ShopShop, one can kill it and leave the room while summoned monsters are still alive to respawn the boss and farm its loot infinitely.
