???'s Soul is an unlockable trinket.
Effect
- Spawns a familiar that floats slowly around the room on a zig-zag pattern similar to
The Peeper and fires spectral and homing tears that deal 3.5 damage.
Notes
- Unlike The Peeper, ???'s Soul does no contact damage.
- ???'s Soul is unable to shoot while flying over obstacles (which is the same behavior that Ghost Baby has).
