Elemental Skill: Swallow-Wisp Pinion Dance

Summoning forth the Swallow-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 Swallow-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: Swallow-Wisp Pinion Dance, 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.
