Genshin Impact Yanfei Build and Character Guide

Legal expert by day; pyromaniac by night.

by Brandon Adams


Yanfei is the latest 4-star character to debut in Genshin Impact, and the first of two new characters introduced in Version 1.5. Easily the best legal advisor in Liyue Harbor, Yanfei also happens to be part Illuminated Beast (much like Ganyu). Yanfei doesn’t have a contract with the Geo Archon, but that doesn’t mean she can’t hold her own in a fight thanks to her Pyro vision and catalyst.

Yanfei Build Suggestions in Genshin Impact

Yanfei is a potent damage-dealer, and essentially all of her damage is Pyro, but it’s all that Pyro that also makes her an excellent support. She can work well as a primary or secondary DPS, but she’ll need a team that’ll help her push Pyro-based elemental combos since her kit only benefits her. That said, Yanfei is a solid support while undergeared in Genshin Impact if you want to use her to setup powerful elemental combos since Pyro remains the best element in the game and she can easily light the world on fire.


Since Yanfei is a catalyst user she has a few solid options at first glance, though the majority are locked behind either the weapon banner, or battle pass. The 4-star Solar Pearl is an excellent weapon for Yanfei, and can be earned by reaching rank 25 in the battle pass. That said, Yanfei’s passive Blazing Eye benefits from Crit Rate, making the 4-star Royal Grimoire an equally potent option, especially when paired with her best artifact set.

Other than those, the 4-star catalyst Sacrificial Fragments is a sold filler weapon for Yanfei, so use it if you have it on hand and not the others. The 5-stars Lost Prayer to the Sacred Winds and Skyward Atlas aren’t terrible since they will passively improve Yanfei’s Elemental Damage, but the 4-stars are easier to grab and are arguably better.

  • Solar Pearl: Normal Attack hits increase Elemental Skill and Elemental Burst Damage by 20% (up to 40%) for 6s. Likewise, Elemental Skill or Elemental Burst hits increase Normal Attack Damage by 20% (up to 40%) for 6s. Secondary: Crit Rate.
  • Royal Grimoire: Upon dealing damage to an opponent, increases Crit Rate by 8% (up to 16%). Max 5 stacks. A Crit hit removes all existing stacks. Secondary: Attack.
  • Sacrificial Fragments: After dealing damage to an opponent with an Elemental Skill, the skill has a 40% (up to 80%) chance to end its own CD. Can only occur once every 30s (down to 16s). Secondary: Elemental Mastery.
  • Lost Prayer to the Sacred Winds: Increases Movement Speed by 10%. When in battle, gain an 8% (up to 16%) Elemental DMG Bonus every 4s. Max 4 stacks. Lasts until the character falls or leaves combat. Secondary: Crit Rate.
  • Skyward Atlas: Increases Elemental Damage Bonus by 12% (up to 24%). Normal Attack hits have a 50% chance to earn the favor of the clouds. which actively seek out nearby opponents to attack for 15s, dealing 160% (up to 320%) Attack Damage. Can only occur once every 30s.


Since Yanfei predominately deals Pyro Damage you will want artifacts that either bolster her Pyro damage, or improve her Pyro-based elemental combos (like Melt and Vaporize). Also, her Elemental Skill is on a decent 9s cooldown, which synergizes perfectly with a set that happens to bolster both of those traits.

The best artifact set for Yanfei in Genshin Impact (at least on paper, since we have yet to get our hands on her as of publication) is Crimson Witch of the Flames. Lavawalker may look appealing, but there’s a bit of a problem with it’s 4-piece: it increases regular damage by 35% towards enemies affected by Pyro. It’s a solid filler set for Yanfei, because you’ll likely grab a few pieces as you farm Crimson Witch of the Flames, but you’ll want to replace it with Crimson as soon as you are able.

With Yanfei you’ll be looking for Attack Percentage and Pyro Damage first, followed by Crit Rate and Elemental Mastery, so as appealing as the Lavawalker bonus may seem the flat bonus to Pyro Damage on Crimson Witch’s 2-piece is superior. That, and the 4-piece bonus on Crimson not only allows you to set up some destructive elemental combos, but synergizes wonderfully with Yanfei’s Elemental Skill cooldown (which further boosts the 2-piece bonus).

  • Crimson Witch of the Flames (Hidden Palace of Zhou Formula)
    • (2) Pyro Damage Bonus +15%
    • (4) Increases Overloaded and Burning Damage by 40%. Increases Vaporize and Melt Damage by 15%. Using an Elemental Skill increases the 2-Piece Set Bonus by 50% of its starting value for 10s. Max 3 stacks.
  • Lavawalker (Hidden Palace of Zhou Formula)
    • (2) Pyro Resistance increased by 40%
    • (4) Increases Damage against opponents affected by Pyro by 35%
