In-game pickup line
“Spin the black circle!”
Mechanics
What Black Powder does
- Completing a circle with Isaac's movement leaves a pentagram on the floor.
- Enemies caught inside take damage while the mark persists.
In a run
Practical note
Circle a slow enemy when there is enough room to finish the shape safely.
