Best Yanfei Genshin Impact build: Artifacts, weapons, more

Yanfei in Genshin ImpactHoYoverse

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 the best build right here, 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’s a few tricks you’ll need to make the most of that though.

Thankfully, this guide covers them all ⁠— as well as Yanfei’s best build in Genshin Impact with the top artifacts and weapons you need to farm for. Here’s what you need to know.

Yanfei’s entire kit revolves around two things: Charged Attacks and Scarlet Seals.

Yanfei abilities in Genshin Impact

Normal Attack: Seal of Approval

  • Normal Attack: Yanfei shoots fireballs that deal up to three counts of Pyro DMG. When Yanfei’s Normal Attacks hit enemies, they will grant her a single Scarlet Seal. Yanfei may possess a maximum of 3 Scarlet Seals, and each time this effect is triggered, the duration of currently possessed Scarlet Seals will refresh. Each Scarlet Seal will decrease Yanfei’s Stamina consumption and will disappear when she leaves the field.
  • Charged Attack: Yanfei consumes Stamina and all Scarlet Seals before dealing AoE Pyro DMG to the opponents after a short casting time. This Charged Attack’s AoE and DMG will increase according to the amount of Scarlet Seals consumed.
  • Plunging Attack: Yanfei gathers the power of Pyro, plunging towards the ground from mid-air, damaging all opponents in her path. Deals AoE Pyro DMG upon impact with the ground.

Yanfei’s combos make use of both Normal and Charged Attacks because of her Scarlet Seal passive. Because she generates one seal per Normal Attack up to a maximum of three (or four, once you hit C6), you want to chain together three (or four) Normal Attacks before doing a Charged Attack at basically no stamina cost.

This maximizes her damage while minimizing stamina cost, which for a Catalyst user is huge given the massive disparity in damage between Normal and Charged Attacks ⁠— especially so for Yanfei with all her passives buffing that in particular.

Elemental Skill: Signed Edict

Yanfei’s Skill, Signed Edict, summons blistering flames that deal AoE Pyro DMG. Signed Edict doesn’t do that much damage, but it can max out your Scarlet Seals (and generate Pyro particles).

This is integral to Yanfei’s combo, as you can charge up your Scarlet Seals with Normal Attacks, Charged Attack to use them all, and then use Signed Edict to completely refresh.

Elemental Burst: Done Deal

Yanfei triggers a spray of intense flames that rush at nearby opponents, dealing AoE Pyro DMG, granting Yanfei the maximum number of Scarlet Seals, and applying Brilliance to her.

Brilliance is a buff you want to keep up at all times on Yanfei as it increases her Charged Attack damage. Given her kit is all about that Scarlet Seal up-time combined with Charged Attack damage, it’s a no brainer.

  • Level 1 ⁠— The Law Knows No Kindness: When Yanfei uses her Charged Attack, each existing Scarlet Seal additionally reduces the stamina cost of this Charged Attack by 10% and increases resistance against interruption during its release.
  • Level 2 ⁠— Right of Final Interpretation: Increases Yanfei’s Charged Attack CRIT Rate by 20% against enemies below 50% HP.
  • Level 3 ⁠— Samadhi Fire-Forged: Increases the Level of Signed Edict by 3. Maximum upgrade level is 15.
  • Level 4 ⁠— Supreme Amnesty: When Done Deal is used:
    • Creates a shield that absorbs up to 45% of Yanfei’s Max HP for 15s.
    • This shield absorbs Pyro DMG 250% more effectively.
  • Level 5 ⁠— Abiding Affidavit: Increases the Level of Done Deal by 3. Maximum upgrade level is 15.
  • Level 6 ⁠— Extra Clause: Increases the maximum number of Scarlet Seals by 1.

Best Yanfei artifacts in Genshin Impact

Yanfei has one stellar artifact set in Genshin Impact you want in 100% of cases: Crimson Witch of Flames. It’s the default Pyro DPS set for a reason, with the buffs being too good to look past ⁠— especially when combined with Vaporize.

It’s not the only option though. The 4-Piece Sets of Wanderer’s Troupe and Shimenawa’s Reminiscence are actually very decent on Yanfei, while any offensive 2-Piece combo (like Gladiator’s Finale with Shimenawa’s) can also do the trick at a low cost.

Best Yanfei weapons in Genshin Impact

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.

Yanfei Talent Level-Up and Ascension materials

Yanfei’s Talent Level-Up and Ascension materials can be found all around Liyue ⁠— and are pretty easy to find considering her Passive Talent shows them on a map.

She farms Treasure Hoarder Insignias from Treasure Hoarders, Noctilucous Jade from the various mines around Liyue, and Juvenile Jade from the Primo Geovishap. She also gets Bloodjade Branches from the weekly Azhdaha boss fight, and Gold books from the Liyue character talent material domain.

If you’re trying to figure out what talents to max on Yanfei first, we suggest looking at her Normal Attack because of the buffs you get on your Charged Attack. Then, you want to maximize her Burst, and finally her Skill last.

Best Yanfei team comp

Yanfei pairs perfectly with Xingqiu to proc Vaporize.

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.

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 make 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.
