Moving over 12 meters within 3 seconds grants 5 stacks of Spring Thunder: When dealing damage with Heavy Attacks, Aerial Heavy Attacks, Light Attacks, or Light Attack Charged Skills, consumes 1 stack of Spring Thunder to increase this damage and the HP and Qi damage from the same type of move in the next second by 15%. The damage bonus cannot stack. Spring Thunder can only be gained from moving once per 15 seconds, and retained for up to 12 seconds. While Spring Thunder is active, hitting a target that is Exhausted or has below 30% Qi with a Heavy Attack or Aerial Heavy Attack restores 1 stack of Spring Thunder. This effect can only trigger once every 2 seconds.
