Black Powder is a passive item in The Binding of Isaac, added in the Afterbirth DLC.

Leaves a trail of black powder on the ground as Isaac is walking. Using this powder to form a circle will create a pentagram symbol which deals 10 damage per tick (30 per second) to enemies standing inside it.

The pentagram lasts for 4.5 seconds.

Flying enemies are also affected.

Increases the damage and blast radius of Isaac's bombs. Damage is increased to 185.

Causes fire places to explode and deal 20 damage to enemies when extinguished. This explosion cannot hurt Isaac.
