Lan Yan

Normal Attack
Wields her Feathermoon Rings to perform up to 4 attacks, dealing Anemo DMG.

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

Plunging Attack
Gathers the power of Anemo and 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 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.

"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.

When the dash from the Elemental Skill Swallow-Wisp Pinion Dance hits a target, if it interacts with Hydro/Pyro/Cryo/Electro, the Swallow-Wisp Shield will undergo Elemental Absorption, with the converted shield absorbing DMG from the corresponding element with 250% efficiency.
Additionally, if this use of Swallow-Wisp Pinion Dance causes the Swallow-Wisp Shield to undergo Elemental Absorption, the Feathermoon Rings that Lan Yan throws at her foes additionally deal Elemental DMG equal to 50% of the original in the corresponding Elemental Type. This DMG is considered Elemental Skill DMG.

The Elemental Skill Swallow-Wisp Pinion Dance and the Elemental Burst Lustrous Moonrise deal increased DMG equal to 309% and 774% of Lan Yan's Elemental Mastery respectively.

When Lan Yan is in the party, your characters will not startle Crystalflies and certain other animals when getting near them.
Check the "Other" sub-category of the "Living Beings / Wildlife" section in the Archive for creatures this skill works on.

After triggering the Elemental Absorption from the Ascension Talent "Four Sealing Divination Charms," this instance of Lan Yan's Elemental Skill Swallow-Wisp Pinion Dance will produce another Feathermoon Ring when they are thrown at opponents.
You must first unlock the Ascension Talent "Four Sealing Divination Charms."

While the Swallow-Wisp Shield is active, when your active party member's Normal Attacks deal DMG, 40% of the Shield's DMG absorption will be restored, up to its original maximum absorption. This effect can occur once every 2s.
