Effects[]

Notes[]

  • Floors completed during the Ascent count.
  • Waiting until after the floor is cleared before picking up Lost Soul nearly guarantees a reward payout on the next floor.
  • The ghost can take explosive damage from Isaac, e.g. via placing a bomb.

Synergies[]

  • BFFS! BFFS!: Gives Lost Soul a once-per-room shield, similar to Holy Mantle Holy Mantle.
    • If BFFS! is dropped, the shield will still remain active until taking one hit of damage, acting similarly to Holy Card Holy Card.
  • Forget Me Now Forget Me Now: Restarting a floor prompts Lost Soul to give a reward if it's alive when used.
