Welcome to Pocket Gamer's detailed Genshin Impact Yanfei guide! Yanfei is the child of an adeptus father and a human mother, who was then raised by Madame Ping when her parents left. Later on, she became the legal advisor for Liyue, and she enjoys appraisal and many different types of law.

Despite being half adeptus, Yanfei is not concerned about her adeptal relations and hasn’t signed any contract with the other Adepti to step up when her help is needed. She doesn’t treat humans as beneath her and is a generally kind person who tries to live the most human life possible.

Best Build for Yanfei in Genshin Impact

Yanfei kicks the law's and your enemies' butts with some serious Pyro flare. Her Seals scald, and can do even more Pyro damage if you pair her with a weapon like the Lost Prayer to the Sacred Winds, which boosts Elemental damage. If you’re going to maximize that Pyro damage, you need to also equip the Crimson Witch of Flames, to add not only a Pyro bonus but increase her reaction’s damage as well.
