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 touches a Devil Beggar, Blood Donation Machine, or Confessionals, it will use the machine or beggar once for free before dying.
Keeping Found Soul alive is crucial for exploration bonus boost in daily runs.

Synergies[ | ]

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

Active Item Interactions[ | ]

In addition to copying 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:

Interactions[ | ]

Azazel / The Forgotten / Tainted Azazel / Tainted Forgotten / Tainted Lilith / Tainted Magdalene / Tainted Samson: The soul uses none of their inherent tear modifiers or special attacks.
120 Volt: Electric zaps will scale with Isaac's damage, instead of the soul's.
Abyss: Using Abyss will have the locusts orbit the soul. If the soul is dropped or dies, all locusts disappear and do not come back when picked back up or when it respawns next floor.
Anima Sola: Chains the same enemy twice at once, to no further effect.
- Anima Sola + The Battery: Unchaining one of the enemies and using Anima Sola again allows chaining two enemies at once.
Baby-Bender: No homing on the soul.
Bag of Crafting: The soul will swing its own bag alongside Isaac collecting any pickups it hits resulting in pickup disappearance.
BFFS!: Does not affect the soul.
Book of the Dead: Bonies will follow the soul. The orbitals will still orbit around Isaac.
Breath of Life: Will kill the soul at any point during the charge.
Brittle Bones: The soul does not benefit from the tears up.
- Brittle Bones + Hollow Heart: Losing hearts granted to the soul by the trinket will give the soul a tears up for each heart lost.
Car Battery: Will not double any active used by the soul.
Dark Arts: The soul will use Dark Arts along with Isaac. Enemies can be marked by both Isaac and the soul. It will gain its own damage boost.
Dead Sea Scrolls / Metronome: The soul will double only the active effects that it can double.
Dream Catcher: The soul will receive half a soul heart for every new floor he follows Isaac to, allowing him to survive multiple hits and gather up to a maximum of 12 soul hearts. His health resets when the trinket is dropped.
Dull Razor: Allows the soul to activate items that would otherwise be useless, such as Old Bandage, Fanny Pack, Varicose Veins etc. It can also be used to dodge damage.
Everything Jar: Regardless of current charges, the soul will always pay out with a poop on every use of the jar.
Eye of Greed: Coin tears fired still subtract coins.
Gnawed Leaf: Invincibility is independent of Isaac's movement.
Guillotine: No head orbital is granted to the soul. Other stats still apply.
Heartbreak: The ghost gains 2 extra hits per floor and every hit the soul takes will damage all enemies in the room as well. Dropping the trinket and picking it up every time in the room will restore the amount of extra hits, essentially making the Found soul immortal.
Hollow Heart: The soul receives a bone heart at the start of a floor, but only if alive when entering the floor.
IBS: The soul itself can never trigger IBS, however when Isaac receives a poop, so does the soul.
Isaac's Heart: The soul becomes immortal and can not be killed.
Jar of Wisps: The soul will spawn a single random wisp each time, and the amount spawned do not increment with each use.
Lemegeton: The soul will get its own Lemegeton wisps orbiting it, but none of them give their respective item effect.
- Lemegeton + Book of Virtues: Wisps spawned by the soul while Isaac has Book of Virtues will be buffed.
Magic Fingers: The damage is only applied from the soul's part, meaning this item will always deal less damage while the soul is carried around.
Mom's Bracelet: The soul can indeed pick up rocks and throw them, despite lacking sprite work.
Notched Axe: The soul can swing the axe once, then breaks permanently, unable to be recharged.
- Picking Notched Axe from a pedestal by swapping with another active item or by dropping it with Butter! will refresh the Found Soul single use Notched Axe, allowing for infinite used on the floor.
Red Key: With proper placement, the soul can open another red room, for free.
Scissors: The soul will spew its own blood fountain, but no extra head will spawn.
The Scooper: An extra Peeper familiar is not spawned; however, the soul will benefit from the right eye damage boost.
Sharp Key: The soul will throw its own key in tandem with Isaac. The throw still costs one key.
Spirit Shackles: The soul will be chained next to the spot it got hit. Proceeding to not get hit again for a short time will revive the soul as normal.
Super Magnet: The soul will have its own attraction field. No effect on pickups.
Toxic Shock: No effect.
Tractor Beam: The soul does not receive a beam, nor are any of its tears affected by Isaac's beam.
Whore of Babylon: Will always be active on the soul.
Wooden Cross: Both Isaac and the soul will receive a temporary shield; however, when one of them loses it, so does the other.
Empty Heart: The soul will receive an empty heart container every floor; however, the soul cannot collect any Red Hearts, but can receive them via Yum Heart's multiplayer healing.

Trivia[ | ]

This trinket is a reference to Lost Soul.
Found Soul is the rarest Steam achievement unlocked by a single completion mark.

Bugs[ | ]

Bug!	If Found Soul is dropped before its death animation finishes, it will still be available for the current floor if picked up again.

Bug!	Resuming a 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!	When used together with Azazel's Stump, the soul familiar sometimes keeps Azazel's properties (flight and short brimstone) for a few rooms after Isaac has transformed back to normal. Lil Clot also has this bug.

Bug!	If Sulfur has been used in a room before picking up Found Soul, it will retain Brimstone until dropped/killed, even through rooms.

Bug!	Entering one of the portals created by Card Reading, Lil Portal, and Ventricle Razor causes the familiar to become invisible until Isaac drops and picks up the trinket again. Entering a new floor sometimes also causes this bug.

Bug!	It is possible for both Isaac and the soul to target the same enemy/boss with Suplex! (easier to do on enemies with large hitboxes such as Hush). In this case, the enemy/boss may become invulnerable and/or invisible after the slam. Dropping the trinket or having the soul die does not fix the situation.
