What’s the best Genshin Impact Yanfei build?

Best weapon Vaporize: Lost Prayer to the Sacred Winds
Transformative: A Thousand Floating Dreams
Weapon substitutes Vaporize: Cashflow Supervision
Transformative: Sacrificial Fragments
Best artifact set Vaporize: Crimson Witch of Flames
Transformative: Gilded Dreams
Artifact substitutes Shimenawa’s Reminiscence, Marechaussee Hunter (with Furina), or Wanderer’s Troupe
Main stats Vaporize:
  • Sands: elemental mastery or attack%
  • Goblet: pyro damage bonus
  • Circlet: crit rate or crit damage

Transformative:

  • Sands: elemental mastery
  • Goblet: elemental mastery
  • Circlet: elemental mastery
Sub-stats
  • Attack%
  • Crit damage
  • Crit rate
  • Elemental mastery

Yanfei’s best vaporizeDPS  build weapon is Lost Prayer to the Sacred Winds and her best transformative reaction (eg. overloaded and burgeon) weapon is A Thousand Floating Dreams. Her vaporize build favors four pieces of Crimson Witch of Flames with a focus on attack%, pyro damage, and crit stats. Gilded Dreams is Yanfei’s best transformative artifact set and you should go all-in on elemental mastery.

If possible, it’s worthwhile getting Yanfei to level 90, especially in an overload team. She also sees some strong quality of life benefits from her constellations in all roles, with her C4 allowing her to provide a strong shield that makes her a strong support for characters like Genshin Impact’s Hu Tao, and her C6 offering a boost to her stamina so she can use her powerful charged attacks more freely.

How should I use Yanfei?

Yanfei primarily excels in an on-field DPS role, taking the lead in either a vaporize or overload team. She’s a great option for early gameplay, and her ranged attacks have a handy reach. She also has decent reach and damage with her AoE, consistent pyro application, and plenty of F2P and resin-efficient options when it comes to weapons, artifacts, and team builds. Yanfei’s elemental skill and elemental burst require a lot of field time, but their DPS potential makes it all worth it.

However, she has a long charged attack animation which isn’t easy to cancel and doesn’t offer invincibility, leaving her vulnerable to incoming attacks. As she’s also pretty squishy in most builds, you may find yourself relying on highly sought-after shield units to negate this damage.

What are the best Yanfei weapons?

Vaporize Yanfei

The Lost Prayer to the Sacred Winds is our catalyst of choice for vaporize Yanfei, as it compliments the extended on-field time necessary to make the most of her rotations. The crit rate secondary stat, which isn’t very common in catalysts, also works really well for her.

As you’ll discover as we continue through this guide, Yanfei synergizes amazingly with Genshin Impact’s Furina, but her corresponding build is extremely specific. Cashflow Supervision works wonders for Yanfei when she’s working with Furina, thanks to its HP change-based attack buffs and substantial crit rate bonus stat.

Alternatively, The Widsith is a great choice, especially as higher refinement ranks, as Yanfei is one of the few catalyst users capable of making full use of its buffs. Plus, it’s slightly easier to roll into.

Weapon Effect How to obtain

Overload/Transformative Yanfei

Our top weapon picks for overload Yanfei are a bit different to that of Vaporize Yanfei, as your main priority for this role is increasing her elemental mastery as much as possible.

Thanks to its unmatched elemental mastery, A Thousand Floating Dreams is Yanfei’s best-in-slot weapon for overload and burgeon teams. Plus, if other members of the team are struggling to meet their EM requirements, this weapon can help them out too.

Sacrificial Fragments takes the top four-star spot due to its high elemental mastery, despite its skill not being the most useful to her. Refinements don’t change much, so you’re fine at R1 for this one, meaning it’s also a very affordable option.

Magic Guide comes in third, as it offers the third-highest elemental mastery of all the catalysts so far. Its attack doesn’t do much for Yanfei, but with it being a three-star weapon, it’s much cheaper to upgrade and refine than other weapons.

Weapon Effect How to obtain
A Thousand Floating Dreams Bonus effect: elemental mastery
Skill: Party members other than Yanfei will provide her with buffs based on whether their elemental type is the same as her (pyro) or not. If they are pyro, increase elemental mastery by 32. If not, increase Yanfei’s pyro damage bonus by 10%. Each of the aforementioned effects can have up to three stacks. Additionally, all nearby party members other than Yanfei will have their elemental mastery increased by 40. Multiple such effects from multiple such weapons can stack
Weapon event gacha
Sacrificial Fragments Bonus effect: elemental mastery
Skill: After you damage an opponent with Yanfei’s elemental skill, the skill has a 40% chance to end its own cooldown. This can only occur once every 30 seconds
Gacha
Magic Guide Bonus effect: elemental mastery
Skill: Increases damage against enemies affected by hydro or electro by 12%
Gacha
Thrilling Tale of Dragon Slayers Bonus effect: HP
Skill: When you switch characters, the new character taking the field has their attack increased by 24% for ten seconds. This effect can only occur once every 20 seconds

What are the best Yanfei artifacts?

For vaporize Yanfei, we highly recommend using a full set of the Crimson Witch of Flames artifacts to get a healthy pyro damage bonus. However, if you’re using Furina, Marechaussee Hunter is your best bet.

Transformative reaction Yanfei favors Gilded Dreams thanks to its high EM base effect. The four-piece effect is entirely based on reactions, so it suits this build nicely, especially as Yanfei is often the only pyro character on the team so you’ll get plenty of extra EM with each reaction.

Shimenawa’s Reminiscence and Wanderer’s Troupe also offer some nice benefits depending on how you want to build your Yanfei.

Artifact set Effect How to obtain
Crimson Witch of Flames Two equipped: pyro damage +15%
Four equipped: increases overloaded and burning damage by 40%, and vaporize and melt damage by 15%. Using an elemental skill increases two-piece set effects by 50% for ten seconds. Maximum three stacks
Hidden Palace of Zhou Formula domain on Bashui Plain, Wuwang Hill, Liyue
Marechaussee Hunter Two equipped: normal and charged attack damage +15%

Denouement of Sin domain in Belleau Region, Fontaine
Gilded Dreams Two equipped: elemental mastery +80
Four equipped: within eight seconds of triggering an elemental reaction, Yanfei will obtain buffs based on the elemental type of the other party members. Attack is increased by 14% for each party member whose elemental type is the same as Yanfei’s (pyro), and elemental mastery is increased by 50 for every party member with a different elemental type. Each of the aforementioned buffs will count up to three characters. This effect can be triggered once every eight seconds. Yanfei can still trigger its effects when not on the field
Spire of Solitary Enlightenment domain in Avidya Forest, Sumeru
Shimenawa’s Reminiscence Two equipped: attack +18%
Four equipped: when using an elemental skill with 15 or more energy, you lose 15 energy and gain 50% normal/charge/plunging attack damage for ten seconds. This effect won’t trigger again during that duration

What’s the best Yanfei team comp?

Naturally, when picking a team comp for Yanfei, the characters you should choose are reliant on whether you want a vaporize, overload, or burgeon team.

For vaporize teams, she synergizes well with Genshin Impact’s Xingqiu and Genshin Impact’s Bennett. You can fill the spare slot with an anemo unit like Genshin Impact’s Kazuha to shred resistance and reap the benefits of the Viridescent Venerer artifact set, Genshin Impact’s Fischl for additional damage and overloads, or Genshin Impact’s Zhongli to shield her, which helps negate her vulnerability during her long charged attack animations.

Here’s an example of a strong vaporize Yanfei team comp:

First character slot Second character slot Third character slot Fourth character slot
Yanfei iconYanfei Xingqiu iconXingqiu Bennett iconBennett Zhongli iconZhongli

For overload teams, you should go with Genshin Impact’s Fischl and Genshin Impact’s Beidou. The fourth slot can once again be filled with Bennett, Xingqiu, or Zhongli, or you can go with Genshin Impact’s Kokomi, all of which help her survivability without interfering with overload reactions.

Here’s an example of a strong overload Yanfei comp:

First character slot Second character slot Third character slot Fourth character slot
Yanfei iconYanfei Beidou iconBeidou Fischl iconFischl Kokomi iconKokomi

Then there’s the Furina-focused team comp. This is technically still a vaporize team, but Yanfei and Furina’s abilities and kit are so specific that this team deserves its own category:
