Yanfei build guide · GenGuru: Your guru for Genshin Impact

Overview

On-field Pyro damage
Charged Attack damage dealer

Yanfei is a Pyro catalyst user who gathers Scarlet Seals and spends them on Charged Attacks. Normal Attacks give one Seal each, her Elemental Skill gives the full set at once, and each Seal consumed makes the next Charged Attack larger. Her passive adds a Pyro DMG Bonus for every Seal spent and an extra Pyro hit whenever a Charged Attack crits. Her Elemental Burst grants Seals at regular intervals and boosts her Charged Attack damage while she stays on the field.

Give her ATK, Pyro DMG Bonus and crits. She is a good choice for Vaporize teams with an off-field Hydro applier, and she is easy to play because her damage comes from a short, simple loop.

Tips

Use her Skill to get all Seals at once, then do a Charged Attack right away. It is faster than gathering Seals from Normal Attacks.
During her Burst, Seals arrive on their own, so you can fire Charged Attacks with only a short Normal Attack in between.
CRIT Rate matters more than usual because her extra Pyro hit only happens when a Charged Attack crits.
Her Burst buff ends when she leaves the field, so use it right before her damage window starts.
