Effects
Killing enemies grants a soul charge to the Urn, up to a maximum of 20. Killing bosses grants a larger boost. Charges must be used to power Urn of Souls.
Each charge is equivalent to 15 flames over half a second.
On use, emits a stream of blue flames in whichever direction Isaac is facing. Each flame deals 1.5 - 2.1 damage per tick, depending on how far it's traveled, for 22.5-31.5 damage per second. Multiple flame can damage the same enemy simultaneously.
Isaac is also pushed backwards slightly while using it.
Can be fired diagonally.
The fire destroys enemy projectiles, poop, and other fires, but bounces off rocks.
