Yanfei is a 4-star Pyro Catalyst character in Genshin Impact. As a half-adeptus and well-known legal advisor, you'll rarely find Yanfei without a tome of law in her hands.
Today, July 28, is Yanfei's birthday, and players who log in to Genshin Impact will find a small gift from her in their mailbox. For those interested in Liyue's premier legal advisor, here's everything you need to know about Yanfei, including who she is, how to get her, and what her best builds are.
Yanfei Genshin Impact: Everything You Need to Know
Born to an adeptus father and human mother, Yanfei grew up under Madame Ping's care. She's extremely knowledgeable and well-read and understands the workings of the law in every nation in Teyvat.
As a Pyro Catalyst character, Yanfei's normal attacks shoot fireballs that deal Pyro DMG. Her normal attacks grant her a Scarlet Seal, which she can then consume with her charged attack to deal more powerful AoE Pyro DMG.
Yanfei's Elemental Skill summons flames that deal AoE Pyro DMG and grant her the maximum number of Scarlet Seals if it hits. Her Elemental Burst deals AoE Pyro DMG and gives her the Brilliance effect, which periodically grants her a Scarlet Seal and increases her Charged Attack damage.
How to Get Yanfei
If you want to get Yanfei, now is your best chance, because she is currently a rate-up 4-star character on Ayaka's banner, "The Heron's Court". Pulling on her banner will give you a greatly boosted chance of getting Yanfei.
Otherwise, she's also available in the standard Wanderlust Invocation banner, although you'll need a bit more luck to pull her on this banner. Currently there is no way to get Yanfei other than Wishing for her.
How to Build Yanfei
Yanfei is best built as a Pyro DPS. All of her abilities revolve around granting herself Scarlet Seals and utilizing them to deal tons of damage with her charged attacks.
5-star catalysts like Skyward Atlas and Memory of Dust are the best weapons for Yanfei, but there are several 4-star options as well. The 4-star catalyst given out for free in the last patch, Dodoco Tales, is a great weapon for Yanfei due to her constant alternation between normal and charged attacks, especially at refinement 5. The Widsith and Solar Pearl are also great choices.
A 4-piece set of Crimson Witch of Flames is the best artifact set for Yanfei, because it can amplify her Pyro damage and reaction damage.
