Notes[edit | edit source]

  • Judas starts with this item by default.
  • The damage bonus does not stack with multiple uses in the same room or with the tarot card XV - The Devil.
  • While activated, switching items will end the bonus damage effect.
  • Removed in Afterbirth Only guarantees Devil/Angel Rooms on floors that they can normally appear on, and, unlike Goat Head Goat Head, picking up The Book of Belial after killing the boss will not open the Devil/Angel Room door.
