Genshin Impact’s Yanfei is a half-adepti and Liyue’s premier legal adviser. Not only can she offer top-of-the-line legal advice, but she can also pack a punch on the battlefield as a surprisingly powerful four-star pyro catalyst wielder. So if you’d care to read the wavier and sign on the dotted line, we’ll take you through the best Genshin Yanfei build, featuring her skills, weapons, and more.
For those of you who need some extra primogems for the next Genshin Impact banner, take a look at our Genshin Impact codes list. For those of you looking for other strong characters, we have guides that include our recommended builds for Genshin Impact’s Diona, Genshin Impact’s Chongyun, and Genshin Impact’s Sara.
Open your textbooks, let’s find out everything you need to know about Genshin Impact’s Yanfei.
What’s the best Genshin Impact Yanfei build?
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 hydro application, and plenty of F2P and resin-efficient options when it comes to weapons, artifacts, and team builds.
She does have some weaknesses, with her damage not really reaching high enough numbers to contend with other DPS (especially five-star units), and her reliance on heavy stamina consumption due to her charged attack. She also 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.
However, with her cost-efficient building and her great pyro application, she truly is a wonderful unit to fill that fire slot on many F2P teams.
What are the best Genshin Impact 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 |
Gacha |
| 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 |
Gacha |
| 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 |
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’s the best Genshin Impact 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 |
 Xingqiu |
 Bennett |
 Zhongli |
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 |
 Beidou |
 Fischl |
 Kokomi |
