CRIT DMG is increased by 30%. When the equipper lands a hit with a Basic Attack, Special Attack, or Aftershock, they gain 1 stack of a buff. Each stack increases the equipper's CRIT DMG by an additional 10%, stacking up to 3 times. The effect lasts for 30s, with each stack's duration calculated separately, and can only be triggered once per use of a skill. With all 3 stacks, the equipper's Electric DMG increases by 20%.
