Ghost Bombs

Ghost Bombs is a passive item added in The Binding of Isaac: Repentance.

Effects

 * Gives Isaac 5 bombs.
 * Isaac's bombs become spectral, and will pass through objects.
 * Isaac's bombs create ghosts when they explode, which rapidly chase and deal contact damage to enemies.
 * The ghost deals contact damage equal to half of Isaac's damage (2x Isaac's damage per second).
 * After 10 seconds, the ghost explodes, dealing 7 damage to nearby enemies up to 3 times. Isaac does not take damage from the explosion.
 * If there are no enemies in the room, the ghost follows Isaac. However, it cannot follow Isaac between rooms.

Synergies

 * : Spectral bombs are less likely to hit Isaac, but make it harder to blow up specific rocks.
 * : Smaller bombs grant smaller ghosts that seek nearby enemies and explode immediately.

Trivia

 * Defeating Delirium as most tainted characters will unlock their gameplay characteristic. Interestingly, Tainted Lost's passive ability to reroll low quality items is unlocked through defeating The Beast instead.
