Urn of Souls item
Urn of Souls is an unlockable active item in The Binding of Isaac, added in the Repentance DLC.
Description
Makes Isaac pull out (or put away) the Urn that, while out, can be fired by holding the shooting buttons in any direction.
The Urn shoots a constant stream of blue flames that deal 22.5-31.5 damage per second, depending on how far the flames have travelled, plus an additional 4.5 × CurrentFloor damage.
Isaac is pushed backwards while shooting the Urn.
The flames can destroy enemy projectiles and other fires, but will bounce off of rocks.
The Urn can only be recharged by picking up enemy souls that spawn when killing enemies. Up to 20 souls can be stored at once.
Bosses' souls grant a larger boost.
Each soul charge can shoot up to 15 flames over the course of half a second.

Special synergies
The following special synergies and interactions for Urn of Souls have been documented.
| Mod | Item | Synergy |
|---|---|---|
| --- | Book of Virtues | A wisp spawns for every consecutive second of firing the Urn. Wisps occasionally shoot fires that block enemy shots, deal contact damage, and last for 3 seconds before disappearing. The flames deal 10 damage per tick that scale down to 5 damage over the next second (60-30 damage per second). |
| --- | The Book of Belial combined with Judas' Birthright | Replaces the stream of fire with a controllable  Brimstone beam that destroys projectiles and deals more damage the longer it's active, starting from 3.37 + 0.361 × CurrentFloor, going up to 4.2 + 0.45 × CurrentFloor.
Souls spawned by enemies are red, and the HUD icon gains a unique red design. |
| --- | Abyss | Spawns an orange locust that has a chance to set enemies on fire. |
