Dampening

Dampening is a stacking debuff that occurs in Arena matches that run too long, designed to prevent matches from ending in a draw. It reduces healing received and absorption effects by 1% per stack.

Dampening begins after 5 seconds upon starting 2v2 games, or 5 minutes and 5 seconds for any other arena bracket. After dampening starts each player will gain a stack of the debuff every 10 seconds, reducing healing received and damage absorption effects by 1% per stack.
