When a Basic Attack lands a hit, drops 1 [Refracting Feather] behind the target. The feather lasts 15s. This effect can trigger only once every 3s. Up to 3 instances of [Refracting Feather] can exist at the same time. No more feathers will drop while 3 are already present. For each [Refracting Feather] present, increases the caster’s Crit Rate by 6%.
