Found Soul

This article is about **Found Soul**, similar in appearance to Your Soul and Lost Soul.
**Found Soul** is an unlockable trinket added in *The Binding of Isaac: Repentance*.

## Effects

* Summons a Familiar that follows Isaac's exact movements, akin to  Jacob and Esau, that flies and shoots spectral tears.
	+ The ghost uses Isaac's speed, tears, range, shot speed, tear effects, and trinkets, and deals half of 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, the familiar will drop one as well at no cost.
	+ The familiar can press Pressure Plates.
* The familiar dies after taking any damage, and will respawn on the next floor.

## Notes

* If Found Soul is dropped before its death animation finishes, it will still be available for the current floor if picked up again.
* If Found Soul touches a Devil Beggar, Blood Donation Machine, or Confessionals, it will use the machine or beggar once for free and then die.

## Synergies

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

* Locust trinkets

## Active Item Interactions

In addition to copying/doubling many passive items, Found Soul can utilize the same active item as Isaac, effectively doubling them. Items that are affected by Isaac's damage will scale with Found Soul's damage instead. These include, but are not limited to the following:

	+ **Anima Sola** + : Unchaining one of the enemies and using Anima Sola again allows chaining two enemies at once.
