Burn is a system in Basement Moon, a mod for The Binding of Isaac.

A keyword with Potency and Count, each capped at 99. Potency appears to the left of its icon and Count to the right. Gaining only one value also supplies a minimum of 1 of the other value.

An afflicted enemy takes damage equal to Burn Potency on each 10-second tick of the in-game timer. Each tick consumes 1 Count.

If Isaac is afflicted with Burn, each tick instead deals (Potency / 9, rounded up) half-Hearts of damage and consumes 1 Count.

Burn ends when Count reaches 0.
