Upon activation, Isaac will raise the candle above his head. On pressing a fire button, a red flame, similar to a fireplace, will fire in the chosen direction that deals a maximum of 125 damage per flame.
The flame also destroys enemy shots it comes into contact with, which decreases its size each time being hit until the flame is entirely extinguished by this process.
The flame projectile is persistent, and will remain active in the room until it deals a set amount of damage. It can pass over Pits, but can not travel through Rocks or Poop.
