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.
• Bonies deal 8.3 contact damage and 5 damage with thrown bones.
• Black Bonies will explode on death, dealing 40 damage to enemies it hits. The explosion will not hurt Isaac.

Notes

• Using the book in a room that had no enemies or was re-entered does nothing and expends the charge.
• Orbital bones occupy the same area around Isaac as Blue Flies, meaning Isaac can have an incredibly dense ring of bone orbitals around him that nullifies most attacks.
  • Having a large amount of blue flies can create gaps in the ring of bone orbitals that leave Isaac vulnerable in those spots.
• 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 create an effect.
• Destroying Black Poop will damage the friendly Bonies acquired from this item.

Interactions

• Baby-BenderGrants Isaac's familiars homing shots.: No effect.
• Car Battery: Since dead enemies can be animated only once, Car Battery does nothing.
• Contagion: Poison effect can spread to and kill friendly Bonies.
• 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.
• The quote "Rise from the Grave" is a reference to the beginning screen of the video game "Altered Beast".

Bugs

Bug! If sufficiently many bone orbitals are created, other familiars may disappear. Collecting a new familiar or resuming the run will restore the missing familiars.
