Tremor 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.

Explosion damage against an afflicted target triggers Tremor Burst and consumes 1 Count.
→ Enemies are slowed to 50% speed for Potency seconds.
→ If Isaac is afflicted, movement and shooting are blocked for (Potency / 5) seconds instead.

Clearing a room consumes 1 Tremor Count.

Tremor ends when Count reaches 0.
