Yanfei
Who is Yanfei?
Yanfei is a 4★ Pyro Catalyst on-field DPS and versatile shield support from Liyue. As a DPS she excels in Vaporize teams, using a Charged Attack rotation that generates Scarlet Seals (each reducing stamina cost) from Normal Attacks and converts them to burst damage. She also functions as a Pyro shield provider at C4 or higher. Her A4 Passive fires secondary Pyro hits on crits, which must be managed carefully in reaction teams.

Kit Summary
Fires Pyro bolts — generates 1 Scarlet Seal per hit (up to 3 / 4 at C6).
AoE Pyro nuke — generates 3 Scarlet Seals at once; the main burst of damage in her rotation.
Large Pyro explosion + grants maximum Scarlet Seals immediately; at C4 creates a Pyro shield scaling with HP.
On a CRIT hit, Yanfei fires a secondary Pyro application — can interfere with reaction ICD management.

📊 Substats Priority
👥 Best Teams
Vaporize DPS (recommended): Yanfei + Bennett + Xingqiu + Fischl (Overvape)
Vaporize with Furina: Yanfei + Furina + Yelan + Xianyun
Burgeon Reaction: Yanfei + Kokomi + Nahida + Kuki Shinobu
F2P Verdict
Fully viable at C0. The Widsith (free/farmable) or Mappa Mare (craftable) are strong F2P weapon options; Dodoco Tales (event) if available. Build 4pc Crimson Witch (Vaporize) or 4pc Gilded Dreams (Burgeon/Overvape). Her ER need is low (~100–130% with Bennett in double-Pyro). C4 adds a Pyro shield on Burst activation — an important comfort unlock for survivability. C6 grants max 4 Scarlet Seals, eliminating stamina issues.
