The Daybreak Chronicles is the closest fit on the game's own numbers: Chasca's kit multiplies ATK, and a weapon is ranked here on whether its ascension stat and its passive act on that stat. Astral Vulture's Crimson Plumage, Royal Bow and The First Great Magic come next. No playtested ranking has been imported for Chasca, so this is arithmetic over the kit data rather than a damage measurement.
Run Desert Pavilion Chronicle on Chasca, with Viridescent Venerer and A Day Carved From Rising Winds behind it. Main stats are ATK% sands, Anemo DMG Bonus goblet, CRIT Rate / CRIT DMG circlet. Roll substats in the order CRIT Rate > CRIT DMG > ATK% > Energy Recharge.
Talent priority is Normal Attack > Elemental Skill > Elemental Burst. The Elemental Burst costs 60 energy, which is what an Energy Recharge target has to clear.
The strongest team is Chasca, Furina, Yanfei and Bennett, built around Chasca: Anemo · Vaporize.
