Gives Isaac the chance to shoot fires alongside his regular tears that block enemy shots and deal damage to enemies that touch them, similar to those shot by Red Candle.
Fires can block up to four shots and/or deal four ticks of damage before being destroyed, and last up to 10 seconds.
Fires deal 4x Isaac's damage at full durability, 3x Isaac's damage after taking damage once, and 2x Isaac's damage otherwise, for a max possible damage output of 11x Isaac's damage per fire.
The chance to shoot fires depends on Isaac's luck stat, and goes up to 100% at 11 Luck.
