Book of the Dead is an 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 charmed Bony (uncommon).
  • A charmed 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 charmed 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.
