Effects

• If the character has half a red heart or no red hearts after taking damage, it triggers the Book of Shadows effect, creating a shield that nullifies all types of damage for 5 seconds.

• (Added in Repentance) Opens A Strange Door in (Depths) Depths II and its variants that leads to (Mausoleum) Mausoleum/(Gehenna) Gehenna II.
  • Unlike with the Chest entrance, The Polaroid gets consumed by the door and vanishes from Isaac's inventory.
