Nimble Reads the battlefield and switches stance based on unit count. If friendly unit count >= enemy unit count: switches to Execute stance and grants an ATK Speed boost for a duration. If friendly unit count < enemy unit count: switches to Yield stance and grants an ATK Speed boost for a duration.
At battle start, designates the frontmost ally as the White piece (damage received reduced) and the rearmost ally as the Black piece (damage dealt increased). When White advances into enemy territory it converts to Black; when Black is approached by an enemy it converts to White. Each swap triggers once per field.
Fires at multiple targets nearest to her, dealing a percentage of ATK as damage (hits the same target multiple times if fewer targets than projectiles). If target's current energy is below Jiutian's: recovers own energy. If target's current energy is equal to or above Jiutian's: drains target's energy.
When Jiutian Xuannv receives an attack, she summons the Taiji Formation for a duration. During the formation, all incoming damage is 100% nullified and accumulated. After the formation ends, she fires at the nearest enemy dealing the accumulated damage. This skill has a cooldown.
Strengthens Execute and Yield stances. Execute: each attack additionally deals bonus damage based on own ATK and target's max HP (capped). Yield: the first attacks after entering Yield stance deal bonus damage based on own ATK and target's lost HP (capped).
