Skyward Blade is the closest fit on the game's own numbers: Pyro Traveler's kit multiplies ATK, and a weapon is ranked here on whether its ascension stat and its passive act on that stat. Summit Shaper, Fleuve Cendre Ferryman and Absolution come next. No playtested ranking has been imported for Pyro Traveler, so this is arithmetic over the kit data rather than a damage measurement.
Run Crimson Witch of Flames on Pyro Traveler, with Celestial Gift and Silken Moon's Serenade 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 70 energy, which is what an Energy Recharge target has to clear.
Pyro Traveler plays Support in the Mualani team, alongside Mualani, Mona and Sucrose.
