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.

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
Lost Prayer to the Sacred Winds Bonus effect: crit rate
Skill: Increases movement speed by 10%. When in battle, gain an 8% elemental damage bonus every four seconds. Max four stacks. Lasts until Yanfei falls or leaves combat
The Widsith Bonus effect: crit damage
Skill: When a character takes the field, they will gain a random theme song for ten seconds. This can only occur once every 30 seconds.
Recitative: Attack is increased by 60%.
Aria: Increases all elemental damage by 48%
Interlude: Elemental mastery is increased by 240
Dodoco Tales Bonus effect: attack
Skill: Normal attack hits on opponents increase charged attack damage by 16% for six seconds. Charged attack hits on opponents increase attack by 8% for six seconds
Midsummer Island Adventure event
Mappa Mare Bonus effect: elemental mastery
Skill: Triggering an elemental reaction grants an 8% elemental damage bonus for ten seconds. Max two stacks
Forging or Stellar Reunion event

Overload 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.

Sacrificial Fragments takes the top 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 at second, as it offers the second-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
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
Magic Guide Bonus effect: elemental mastery
Skill: Increases damage against enemies affected by hydro or electro by 12%
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?

Regardless of whether you’re using her in a vaporize or overload team, we highly recommend using a full set of the Crimson Witch of Flames artifacts to get a healthy pyro damage bonus. Shimenawa’s Reminiscence and Wanderer’s Troupe also offer some nice benefits depending on how you want to build your Yanfei.

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 or overload 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
