Synergies[ | ]

    • If combined with Collectible 9 Volt icon9 Volt, it will be easier to achieve invincibility.

The wisps have 1 health, but will not be damaged by blocking projectiles, and can only be destroyed on contact with enemies.

  • (except in Rebirth)Collectible Car Battery iconCar Battery: Doubles the duration of invulnerability.
  • Collectible Cube of Meat iconCube of Meat and most other orbitals: Highly effective with Book of Shadows, as Isaac can run into enemies with an active shield to deal massive amounts of damage.

Interactions[ | ]
