Yanfei’s Quest

Yanfei is currently a legal advisor in Liyue Harbor. She is very knowledgeable in many areas of the law and has a strong sense of justice. In fact, she has even found many loopholes that have helped her clients in the past. Despite all the loopholes she finds, Yanfei has never gotten in trouble for tricking the system to get her way. She makes sure to gather all the legal evidence before she makes her argument. Due to the nature of her work, Yanfei is well connected to many of the residents of Liyue, including the traveling merchants that seek out her aide when it comes to handling their disputes.

Fun Fact: Yanfei has a dislike of any food that is cold.

As an adepti that is not bound by the contracts of Rex Lapis, Yanfei was born in an era of peace. She spends most of her time living amongst the mortals, as her parents left to go on a journey. Yanfei has a playful nature, but takes her job as a legal advisor very seriously. Her one wish is for everyone to live an honest life where her role as a legal advisor is no longer needed. When that day happens, Yanfei plans to become a rapper.

Yanfei Skill Talents

Yanfei’s skill set heavily depends on the use of her Scarlet Seal and her charged attack. This Scarlet Seal will boost the damage of her charged attack while decreasing the stamina consumed while the effects are active.

Yanfei’s Normal and Charged Attack

Yanfei normal attack, Seal of Approval, will deal 3 counts of Pyro DMG to the enemy. This attack can rapidly hit the enemy and has a high attack spped. When her normal attack hits an enemy, Yanfei will be granted 1 Scarlet Seal. She can have a maximum of 3 Scarlets Seals. When Yanfei gains a new Scarlet Seal, the duration of her seals will refresh. Depending on the number of Scarlet Seals Yanfei has, her stamina consumption will decrease. The decreased stamina consumption is great to reduce the stamina used when using her charged attack. The Scarlet Seal will remain with Yanfei until the duration runs out or when she leaves the field.

Yanfei’s charged attack will consume all the Scarlet Seals and a portion of her stamina to deal Pyro DMG to enemies. The stamina cost of her charged attack will be reduced by 15% for each Scarlet Seal Yanfei has in her procession. The AoE range and damage will also increase, depending on the number of Scarlet Seals that were consumed at the beginning of her charged attack. As a main DPS, Yanfei’s charged attack will be the main focus point of her builds.

Yanfei’s Elemental Skill

Yanfei’s elemental skill, Signed Edict, will summon flames and deal Pyro DMG to enemies. When her elemental skill hits an enemy, Yanfei is granted the maximum number of Scarlet Seals. This skill is great to automatically get 3-4 Scarlet Seals so you can use her charged attack more frequently. It has a cooldown of 9 seconds. Yanfei’s elemental skill and her normal attack work great together as they will allow her to easily gain the Scarlet Seals needed to increase the damage of her charged attack. Hitting an enemy with her elemental skill will gather 3 elemental particles for her burst.

yanfei's burst explained
Yanfei’s Burst

Yanfei’s elemental burst, Done Deal, will inflict enemies with Pyro DMG in a burst of flames. Her elemental burst will also grant Yanfei the Brilliance effect. The Brilliance will periodically grant her a Scarlet Seal every 1 second for 15 seconds. It will also increase the damage of her charged attack and will stop when the duration ends or when Yanfei leaves the field. Her burst’s main use will be to gather the Scarlet Seals and increase the damage of her charged attack. It does have a 20-second cooldown and 80 energy cost, so it will take a while for her to use it again.

In co-op, Yanfei can deal massive amounts of Pyro DMG and trigger reactions. She is best used to deal damage to enemies, but she is fragile and will need a healer on the team to maintain her health.

Yanfei Passive Talents

Yanfei dps build
Yanfei’s talent screen

Yanfei’s passive talent allows her to find materials easier in Liyue, while her ascension talents boost the power of her charged attack.

Yanfei’s passive talent, Encyclopedic Expertise, displays all resources that are unique to Liyue. This talent is great for resource collecting and is similar to Qiqi’s talent which does the same thing. It doesn’t help Yanfei in combat, but will be helpful in finding materials in Liyue. The icons it displays will be the same regardless of the material.

Yanfei’s ascension 1 talent, Proviso, increases her Pyro DMG when she consumes a Scarlet Seal. A Scarlet Seal is earned through the use of her normal attack talent and is consumed when she does a charged attack. This buff will last for 6 seconds, and will only increase her Pyro DMG by a small amount. Using a charged attack during the buff duration will dispel the previous buff. It is recommended you only use your charged attack when Yanfei has more than 1 Scarlet Seal because her charged attack damage increases based on the number of Scarlet Seals consumed.

Yanfei’s ascension 4 talent, Blazing Eye, allows Yanfei to deal an additional Pyro AoE attack if she lands a critical hit with her charged attack. This attack will be equal to 80% of her attack stat. This talent will only be useful if you have a high Crit Rate on Yanfei, but will overall boost the damage of her charged attack.

Yanfei gets a boost to her Pyro DMG Bonus% based on her ascension rank.

Encyclopedic Expertise
Unlocked Automatically

When Yanfei consumes Scarlet Seals by using a Charged Attack, each Scarlet Seal will increase Yanfei’s Pyro DMG Bonus by 5%. This effect lasts for 6s. When a Charged Attack is used again during the effect’s duration, it will dispel the previous effect.
Blazing Eye
Unlocked at Ascension 4

When Yanfei’s Charged Attack deals a CRIT Hit to opponents, she will deal an additional instance of AoE Pyro DMG equal to 80% of her ATK. This DMG counts as Charged Attack DMG.

Yanfei Constellations

Yanfei c0 build
Yanfei’s Constellations

Yanfei’s constellations are rather lackluster until you reach her constellation 6 because they don’t heavily impact her playstyle. Her most important constellations are her second and sixth levels.

At C1: The Law Knows No Kindness, Yanfei’s Scarlet Seal will further increase the reduction of her stamina when using her charged attack. Yanfei’s resistance to interruption will also be increased. The Scarlet Seals already decreases the stamina consumed by a good amount without this constellation. It is helpful to have, but not necessary for Yanfei to be viable in battle.

C2: Right of Final Interpretation boosts Yanfei’s Crit Rate against enemies below 50% of their health when she uses her charged attack. This will further boost Yanfei’s damage when she uses her charged attack, but is limiting as it will not activate unless the enemy has below 50% of their HP. It is great during boss fights as it may give you the extra push you need to defeat them. It also works great with her ascension 4 talent that will deal extra damage to enemies when she lands a critical hit with her charged attack.

C4: Supreme Amnesty allows Yanfei to create a shield after she casts her burst. This shield will absorb damage based on Yanfei’s Max HP and will also be more effective against Pyro DMG. This shield will help reduce the damage Yanfei takes as she is rather frail. However, it is based on her health so it will be hard to balance powering up her shield or her attack.

C6: Extra Clause increases the maximum number of Scarlet Seals Yanfei can have to 4. This constellation will allow her to gain an extra seal, boosting the damage of her charged attack. The extra seal will also help further reduce the stamina she consumes while using her charged attack. It is the most useful of her constellations, but will be hard to obtain right away.

Constellation LevelsEffects
C1: The Law Knows No KindnessWhen Yanfei uses her Charged Attacks, each existing Scarlet Seal additionally reduces the stamina cost of this Charged Attack by 10% and increases resistance against interruption during its release.

Charged ATK Build

main dps Yanfei build
Yanfei Charged Attack Build

Yanfei’s charged attack is the main focus point of her skill set. Both of her ascension talents boost the power of her charged attack. However, Yanfei’s ascension 4 skill does require her to land a critical hit with her charged attack to activate its effects. This build for Yanfei uses the 4-piece Wanderer’s Troupe to further boost the damage of her charged attack. With her Scarlet Seals, Yanfei can reliably use her charged attack as each Scarlet Seal will decrease her stamina consumption and increase the damage of her charged attack. For this build, you will want to max out Yanfei’s normal attack talent. Both her elemental skill and burst are able to supply her with Scarlet Seals, and you can also level them up to increase their damage. It is important to note that her burst does require 80 energy to recharge and may take a while to charge up without another Pyro character or Energy Recharge in her artifacts. This build can work as a Sub-DPS or Main DPS Yanfei.

Yanfei’s teammate can include a variety of characters, but you should have a strong healer on the team as Yanfei is fragile and can easily get hurt. She can be paired with Diona who can heal Yanfei and protect her from harm. Diona is also capable of further decreasing Yanfei’s stamina consumption while she is protected by her shield and decreasing enemy attack with her elemental burst. Xiangling will be used to activate the Pyro team resonance to increase the ATK stat of the entire team. At C6, Xiangling can even increase Yanfei’s Pyro DMG while her burst is active. Xiangling can be replaced with any Pyro character like Bennett. Fischl will be used to deal passive Electro damage to enemies with her elemental skill and trigger reactions. She can be replaced with any character of your choice.

For Yanfei’s recommended weapon, your best option is either the 5-star Lost Prayer to the Sacred Winds or the 4-star The Widsith. The Lost Prayer to the Sacred Winds has a critical rate passive stat and can boost Yanfei’s elemental bonus and movement speed in its passive effect. Any of the 5-star weapons can also work for Yanfei if you have the right setup. For example, the Memory of Dust requires Yanfei to maintain a shield to increase her attack.

The Widsith will give Yanfei one of the following effects when she is switched into:

  • Recitative: Increases Base ATK
  • Aria: Increases all Elemental DMG
  • Interlude: Elemental Mastery is increased

This effect will last for 10 seconds and can only occur every 30 seconds. Its effects will also be strengthened based on the weapon’s refinement level. Although the buffs are random, each one will allow Yanfei’s charged attack to deal more damage. This weapon comes with a critical damage increase, making it the perfect weapon for a Yanfei who has a high critical rate.

If you have a Cryo character on the team, Yanfei is able to make use of the craftable 4-star weapon Frostbearer. This weapon will further increase her attack and has a chance to drop an icicle on the enemy when she hits them with a normal or charged attack. If the enemy is affected by Cryo, they will be dealt an additional blast of damage.

You can also equip Yanfei with the Blackcliff Amulet from the shop. It will increase her critical damage and boost her attack after she defeats an enemy. The major disadvantage of this weapon is that it requires Yanfei to defeat an enemy before the buff can trigger.

For Yanfei’s artifact set, you will want to equip her with the 4-piece Wanderer’s Troupe. This set will boost her reaction damage and increase the damage of her charged attack. You can also use the 4-piece Crimson Witch of Flames to boost her Pyro DMG and Pyro reaction damage.

For the main stats:

  • Sands: ATK%
  • Goblet: Pyro DMG%
  • Circlet: Crit Rate (Crit DMG if your Crit Rate is already high)

In the artifact’s sub-stat, look for Crit Rate, Crit DMG, ATK%, and Elemental Mastery. Energy Recharge will also work if you want to recharge her burst faster.

Main DPS Build

best builds for Yanfei
Main DPS Yanfei Build

This build for Yanfei will focus on her overall Pyro DMG and reaction power. Instead of just focusing on her charged attack, Yanfei is capable of triggering reactions with all of her attacks. Her normal attack can rapidly fire Pyro DMG at enemies, while her elemental skill has a 9-second cooldown and can hit enemies that are clustered together. Yanfei’s charged attack can also be used if you want as most of her skillsets heavily rely on the use of her charged attack.

Yanfei’s teammate for this build will be centered around the Melt reaction. Both Ganyu and Qiqi will apply Cryo to the enemies. In addition, Qiqi can also heal the team while Ganyu has a wide range on her burst that can inflict Cryo DMG to enemies. Having two Cryo characters will trigger the Cryo team Resonance to boost the Crit Rate of attacks against enemies affected by Cryo. Lastly, Sucrose will increase the elemental mastery of the team, allowing their reactions to deal more damage.

For her recommended weapons, Yanfei can use any of the weapons suggested above like the Lost Prayer to the Sacred Winds or The Widsith. She can also make use of the 5-star Skyward Atlas which will increase her ATK. This 5-star weapon can increase Yanfei’s elemental damage and has a chance to summon a cloud to deal damage to enemies. To trigger this cloud, Yanfei must hit an enemy with her normal attack talent.

Yanfei’s other recommended weapon is the 4-star Mappa Mare which has a passive stat in Elemental Mastery. This weapon can be crafted and has a passive skill that will grant Yanfei an elemental damage bonus when she triggers a reaction. Likewise, the 4-star Sacrificial Fragments can also increase Yanfei’s EM and has a chance to end the cooldown of her elemental skill when she uses it to damage an enemy. The Sacrificial Fragments will allow Yanfei to use her elemental skill more often to gather Scarlet Seals while the Mappa Mare will increase her overall elemental damage.

If you have access to the battle pass, then the 4-star Solar Pearl can also be a decent option for Yanfei. This weapon can increase her critical rate and its passive effect increases the power of her normal attack after she uses her elemental skill and burst. It will also increase the power of her skill and burst after she uses her normal attack. However, this weapon does not increase the power of her charged attack, which Yanfei relies on to deal damage.

For her artifacts, Yanfei should be equipped with the 4-piece Crimson Witch of Flames. This set will increase her Pyro DMG% and allow her to deal more damage when she triggers a reaction.

The artifact’s main stats should be:

  • Sands: ATK%
  • Goblet: Pyro DMG%
  • Circlet: Crit Rate or Crit DMG%

Look for Crit DMG, Crit Rate, and ATK%, in the sub-stat. If you are using Sucrose on the team, then EM is not needed as she will provide a portion of her elemental mastery to the team with her skills.


Fischl will be used to deal passive Electro DMG and trigger reactions with her elemental skill Oz.

Xiangling will trigger the Pyro team resonance with Yanfie to give the entire team a buff to their attack. She can be replaced with any Pyro character of your choice.

Diona will be used to shield Yanfei from damage while also healing her with her burst. She can also be used to decrease the enemies’ attack and decrease the stamina consumed for the character she protects with her shield if you have her ascension talents unlocked.

Qiqi is a great healer and can also apply Cryo to enemies for reactions.

Ganyu is a powerful DPS character with a wide range on her burst and charged attack.

Sucrose’s main role will be to boost the reaction damage of the team. She can also act as crowd control to pull enemies closer together.

Yanfei explained and builds
Yanfei’s Deductions

Yanfei is a pyro catalyst that relies on the use of her Scarlet Seal and her charged attack to deal increased Pyro DMG to enemies. Her skillsets allow her to easily gather the Scarlet Seals, giving her decreased stamina consumption and increased damage on her charged attack. Her normal attack can also fire rapidly off at the enemy to deal Pyro damage while both her skill and burst can reliably give her more Scarlet Seals. As a catalyst character, Yanfei should stay away from the enemies as she has weak defenses and can easily die from enemy attacks. She also does not have any support skills for the team as her Scarlet Seals only works on herself. She is an overall solid Pyro character that’s primary use is to deal damage and trigger reaction with her attacks.
