When the equipper's Aftershock hits an enemy, causing Electric DMG, the target's DEF is reduced by 25% for 5s. Passive effects of the same name do not stack. When this effect is triggered, if the equipper is not the active character, they gain 1 stack of Spirit Lock, up to a maximum of 3 stacks. This can trigger only once per use of a skill. Each stack of Spirit Lock increases the equipper's Impact by 4%, lasting 12s. The duration of each stack is calculated separately. At full stacks of Spirit Lock, the equipper's Impact increases by an additional 8%.
