Upon launching a Quick Assist or Perfect Assist, the equipper's Impact increases by 25% for 8s. When the equipper launches and hits an enemy with a Basic Attack, apply Wilt to the target for 30s, stacking up to 20 times, repeated triggers reset the duration. When any squad member hits an enemy, for every stack of Wilt applied to the target, the CRIT DMG of the Ice DMG and Fire DMG dealt by that attack increases by 1.5%. Only one instance of this effect can exist in the same squad.
