Dealing Wind DMG inflicts Wind Anomaly Buildup on enemies and inflicts the Windswept state. Entering the Windswept state interrupts enemy actions and deals massive Wind DMG. While enemies are in the Windswept state, direct Wind DMG they take is increased based on the Wind Anomaly trigger's Tempest Coefficient. The first time the enemy takes Fire DMG, Ice DMG, Electric DMG, Physical DMG, or Ether DMG, the corresponding Contamination effect is triggered. While under Contamination, both direct Wind DMG and direct DMG from the triggering Contamination attribute are increased based on the Wind Anomaly trigger's Tempest Coefficient. During a single Windswept instance, Contamination can only be triggered this way once. After triggering Vortex, it is forcibly converted into the Vortex's corresponding Contamination state.
When the equipper uses an EX Special Attack, their Anomaly Proficiency increases by 25 for 40s, stacking up to 2 times. Repeated triggers reset the duration. When the equipper triggers Windswept, their DMG increases by 18% for 40s. Repeated triggers reset the duration.
