Hungry Soul

Hungry Soul is an unlockable passive item added in The Binding of Isaac: Repentance.

Effects[ | ]

Grants Isaac a chance to spawn a friendly ghost upon killing an enemy, which rapidly chases down and deals contact damage to enemies.
- The chance to spawn a ghost is 33% and is not affected by luck.
- Ghosts deal contact damage equal to half of Isaac's damage, 4 times per second (2x Isaac's damage per second).
After 7 seconds, the ghost explodes, dealing 7 flat damage to nearby enemies up to 3-4 times.
- The explosion cannot damage Isaac or the environment.

Enemies killed by ghosts are unable to spawn more ghosts, except for those killed by the ghost's final explosion.
The ghost's explosion is capable of damaging friendly monsters, such as Bonies summoned by Book of the Dead.
Ghosts cannot be taken outside the room they spawned in.
The ghosts are not considered to be familiars and as such aren't affected by any items that modify the behavior of familiars.
- This also means that Isaac can have more than 64 ghosts at a time and this won't override other familiars.
