Normal Attack
Wields her ring blades and performs up to 4 attacks using them, dealing Anemo DMG.

Charged Attack
Consumes a certain amount of Stamina to throw out a ring blade, dealing Anemo DMG.

Plunging Attack
Plunges towards the ground from mid-air, damaging all opponents in her path. Deals AoE Anemo DMG upon impact with the ground.

Summoning forth the Phoenix-Wisp Shield, a secret art passed down across generations, Lan Yan dashes forward and, upon making contact with her target, will leap back into the air.
The Phoenix-Wisp Shield's DMG absorption scales based on her ATK, and has a 250% absorption efficiency against Anemo DMG.
While in mid-air due to the effects of her Elemental Skill, pressing her Elemental Skill again or pressing Normal Attack will cause Lan Yan to hurl her Feathermoon Rings at an opponent, and they will spin between nearby opponents twice upon hit, dealing Anemo DMG.
Holding the Skill will cause it to behave differently.

Hold
Enter Aiming Mode to adjust the dash direction.

"The clouds cut the lunar light, like shadows silver gracing one's sight."

Lan Yan creates a Feathermoon Swallow Array, pulling in nearby opponents and objects and dealing multiple instances of AoE Anemo DMG.

Strictly speaking, with only Lan Yan herself present, it cannot properly be called an "array." However, if her Rattan Figures are brought into the picture, she can sort of fulfill the requirements ...Probably.
