This gem makes each attack that hits an enemy grant increased Attack Speed and dodge chance, stacking until maximum and refreshing all stacks on each application. Upgrading only increases the dodge chance gained. At rank 25, it also gives cooldown reduction for every active stack. However, due to the way this stat works, one needs to build up stacks before using the skill with cooldown, which is easily done for rapid cooldowns, but can be difficult to do for abilities that recharge longer."@en .
