Found Soul is an unlockable trinket added in The Binding of Isaac: Repentance.


  • Summons a Familiar that follows Isaac's exact movements, akin to Jacob and Esau Jacob and Esau, and shoots spectral tears.
    • The ghost uses Isaac's speed, tears, range, shot speed, tear effects, and trinkets, and deals 0.5x Isaac's damage.
    • The familiar has collision and can be separated. Holding down the "drop" button keeps the familiar in place.
    • When Isaac places a Bomb Bomb, the familiar will drop one as well at no cost.
    • The familiar can press Silver Button Buttons.
  • The familiar dies after taking any damage, and will respawn on the next floor.

Found Soul is capable of copying the effects of most items, including but not limited to:

Active Item Interactions[]

    • Lemegeton + Book of Virtues Book of Virtues: Wisps spawned by the soul while Isaac has Book of Virtues will be buffed.

In-game Footage[]


  • This trinket is a reference to Lost Soul Lost Soul.
  • The text when picking up the trinket, "Finally!," is a reference to the "Finally, Upgrade" meme.


Bug Bug! Resuming a Jacob and Esau Jacob and Esau run with Found Soul equipped in Esau's trinket slot will require a controller to continue. If a controller is available and plugged in, Found Soul can be controlled like a Co-op baby and won't mimic either brother's movements. This effect won't happen if Jacob holds the trinket. If no controller is available, the run is softlocked and cannot be continued.
Bug Bug! When used together with Azazel's Stump Azazel's Stump, the soul familiar sometimes keeps Azazel Azazel's properties (flight and short brimstone) for a few rooms after Isaac has transformed back to normal. Lil Clot Lil Clot also has this bug.
Bug Bug! If Sulfur Sulfur has been used in a room before picking up Found Soul, it will retain Brimstone until dropped/killed, even through rooms.
Bug Bug! The game will crash if Found Soul collides with a Confessional.png Confessional, and the game will crash upon attempting to reload the run, effectively terminating it.
