Defeat Delirium as The ForgottenBook of the Dead

Book of the Dead is an unlockable active item added in Booster Pack #5.

Effects

• When used, spawns one of the following things for each enemy already killed in the current room:
  • An orbital bone familiar (very common).
  • A friendly Bony (uncommon).
  • A friendly Black Bony (rare).
• Orbital bones deal contact damage equal to Isaac's damage at the time it was spawned, repel enemies that touch it, and will block 3 shots or deal 2 ticks of contact damage before being destroyed.
• Bonys deal 8.3 contact damage and 5 damage with thrown bones.
• Black Bonys will explode on death, dealing 40 damage to enemies it hits. The explosion will also hurt Isaac if he is in range.

Notes

• Using the book in a room that had no enemies or was re-entered does nothing and expends the charge.
• Enemy remains can be animated only once, so using the book multiple times in the same room requires more enemies to have died for it to have an effect.
• Destroying Black Poop will damage the friendly Bonys acquired from this item.

Interactions

• Baby-BenderGrants Isaac's familiars homing shots.: No effect.
• Car BatteryCauses Isaac's activated item to activate twice on each use.: Since dead enemies can be animated only once, Car Battery does nothing.
• ContagionThe first enemy killed in a room explodes and poisons nearby enemies. Poisoned enemies will also explode upon death.: Poison effect can spread to and kill friendly Bonys.
• Duct TapeStops Isaac's familiars from moving.: Only affects orbitals.

Unlockable achievements

• 

  Mystery Egg - Spawn three charmed enemies in the same room.

Trivia

• The Book of the Dead is a collection of ancient Egyptian funerary texts made out of papyrus, consisting of magic spells intended to assist a soul's journey through the Duat (underworld) and into the afterlife.
