Your skills come back 2 s sooner, but luck turns against you: everything random rolls worse.

Game text: «All skill cooldowns are reduced by 2 (+1 per stack) seconds. All random effects are rolled +1 (+1 per stack) times for an unfavorable outcome.»

Stacking: Each copy adds the same, no cap.

Watch out: Cooldowns never go below half a second. Each Purity cancels a Clover. Does not affect Tougher Times.
