Memory of Dust is the closest fit on the game's own numbers: Lan Yan's kit multiplies ATK, and a weapon is ranked here on whether its ascension stat and its passive act on that stat. Angelos' Heptades, Oathsworn Eye and Crane's Echoing Call come next. No playtested ranking has been imported for Lan Yan, so this is arithmetic over the kit data rather than a damage measurement.
Run Desert Pavilion Chronicle on Lan Yan, with Viridescent Venerer and A Day Carved From Rising Winds behind it. Main stats are ATK% sands, ATK% goblet, ATK% circlet. Roll substats in the order Energy Recharge > ATK% > CRIT Rate > CRIT DMG.
Talent priority is Elemental Burst > Elemental Skill > Normal Attack. The Elemental Burst costs 60 energy, which is what an Energy Recharge target has to clear.
