Best Yanfei Genshin Impact build: Artifacts, weapons, more

Yanfei in Genshin Impact

The half-adepti Yanfei can basically summon the power of the gods in Genshin Impact to deal massive amounts of damage as a Pyro Catalyst. If you want to do just that, follow our best build, including Yanfei’s top artifacts and weapons.

Yanfei might prefer to do things via law and contracts, but Liyue’s most sought-after legal advisor can definitely lay down the law in a different way ⁠— through raw Pyro power.

The four-star Catalyst dishes out massive damage with a kit that purely focuses on Charged Attacks and weaving them perfectly around Elemental Reactions to maximize DPS. There are a few tricks you’ll need to make the most of that, though, and we’ve got all the best build details right here.

Best weapons for Yanfei

Yanfei’s best weapons in Genshin Impact do two things: buff up her Charged Attacks while also increasing CRIT Rate (and DMG). While Lost Prayer to the Sacred Winds doesn’t really do the former, the damage bonus based on field time is incredibly strong, given how much Yanfei demands.

Outside of the five-star option, she can actually be built pretty cheaply otherwise. The Widsith is flexible, with Yanfei utilizing all three buffs. The free-to-play Mappa Mare is also incredibly powerful, given it’s both cheap and gets stronger based on reactions, something Yanfei constantly procs.

Here’s a list of Yanfei’s best weapons in Genshin Impact:

Best Yanfei team comp

Yanfei has a couple of team comps she can fit into, but the best is utilizing her as an on-field carry and prioritizing Vaporize reactions.

This is where star support duo Bennett and Xingqiu come in. Bennett is great for buffing Yanfei’s ATK as well as giving Pyro Resonance, while Xingqiu is the best off-field Hydro applier in the game.

Yanfei functions best with a vaporize team.

To round out the squad, you can either add an Electro character like Fischl for more reactions or an Anemo character like Sucrose or Kazuha for Viridescent Venerer shred (best).

There is a Yanfei build that goes all in on Overload instead, synergizing with Electro characters. The common pairing of Fischl and Beidou makes an appearance because of their powerful off-field damage, but you will have to change some parts of your Yanfei build to fit it in. Elemental Mastery is a key stat on your artifacts, while Sacrificial Fragments is the weapon of choice.
