Genshin Impact Yanfei Guide

Introduction to Yanfei

Genshin Impact Yanfei is a four-star Pyro Catalyst user who scales primarily off Attack and excels as an on-field Pyro DPS. She is a half-illuminated beast with adeptal heritage and serves as Liyue’s top legal adviser, valuing fairness and ensuring that contracts are upheld to the highest standard. Unlike many others in Liyue, she has not signed a contract with Rex Lapis, preferring to maintain her own sense of freedom. Genshin Impact Yanfei is permanently available in the Standard Banner and also appears in limited-time character event banners, with her most recent rerun taking place in the second phase of Genshin Impact 4.5.

As a Pyro character, Yanfei has strong elemental application, with all her attacks dealing Pyro damage, making her highly effective for triggering Elemental Reactions such as Vaporize and Melt. She specializes in Charged Attacks, which gain benefits from her Scarlet Seals mechanic. Scarlet Seals are generated when she lands Normal Attacks, reducing the stamina cost of her Charged Attacks and increasing their damage output. When she has enough Scarlet Seals, her Charged Attacks cost no stamina, allowing her to unleash consistent bursts of Pyro damage without worrying about stamina depletion. This makes her an efficient DPS choice, as she can maintain strong damage output while preserving stamina for dodging and repositioning.

In addition to her offensive capabilities, Genshin Impact Yanfei gains defensive utility at her fourth constellation, which grants her a shield upon using her Elemental Burst. This shield provides added survivability, making her slightly less reliant on external shielding or healing. While Yanfei does not require constellations to function well as a DPS, her later constellations enhance her overall effectiveness by improving her Charged Attack consistency and adding defensive layers to her kit. As a Catalyst user, she applies Pyro effortlessly with every attack, ensuring that she remains a valuable choice for teams built around Elemental Reactions.

However, she does have some weaknesses. Yanfei can struggle with energy management, making it difficult to consistently activate her Elemental Burst without external Energy Recharge support. Her Charged Attack animation is relatively long, leaving her vulnerable to enemy attacks if she is not protected by shields or careful positioning. Additionally, if she lacks Scarlet Seals, her Charged Attacks consume a significant amount of stamina, which can make sustained damage output more difficult in prolonged fights. Another downside is that sprinting or jumping can interrupt her Charged Attack animation, causing her to lose damage potential if mistimed.

While Genshin Impact Yanfei remains a solid Pyro DPS option, her overall damage output can be lower than many of the game’s top-tier Pyro characters, making her less favorable in high-end content where optimized damage is necessary. However, for players looking for a consistent and easy-to-use Pyro Catalyst user with strong reaction potential, Yanfei offers a reliable choice, particularly in early and mid-game content. With proper investment, she can still perform well in many team compositions, especially when paired with Hydro or Cryo characters to maximize her Elemental Reaction damage.

Abilities and Talents

Normal Attack	Signed Edict	Done Deal	Proviso	Blazing Eye	Encyclopedic Expertise

Yanfei’s Playstyle and Scarlet Seal Mechanic
Yanfei’s kit in Genshin Impact revolves around generating and consuming Scarlet Seals to enhance her Charged Attacks, dealing powerful Pyro damage. Her Normal Attack, Seal of Approval, fires up to three Pyro-infused fireballs, with each hit granting a Scarlet Seal. She can hold up to three Scarlet Seals, or four if she has her sixth constellation unlocked.

Each Scarlet Seal reduces the stamina consumption of her Charged Attack and disappears when she leaves the field. Her Charged Attack consumes all Scarlet Seals and stamina to deal AoE Pyro damage, with both the AoE and damage increasing based on the number of seals consumed. Yanfei’s Plunging Attack gathers Pyro energy before striking the ground, dealing AoE Pyro damage upon impact.

Elemental Skill – Signed Edict
Yanfei’s Elemental Skill, Signed Edict, releases blistering flames that deal AoE Pyro damage. If this attack hits an enemy, Yanfei immediately gains the maximum number of Scarlet Seals, allowing her to perform a stronger Charged Attack with reduced stamina cost. This ability is useful for quickly setting up powerful Charged Attacks without the need for multiple Normal Attacks.

Elemental Burst – Done Deal
Her Elemental Burst, Done Deal, releases a spray of flames that deal AoE Pyro damage, granting her the maximum Scarlet Seals and applying Brilliance. Brilliance periodically grants Yanfei additional Scarlet Seals and increases her Charged Attack damage. This effect lasts for the duration of the Burst but ends if Yanfei leaves the field. Done Deal allows for a more sustained damage output, ensuring her Charged Attacks remain efficient and powerful.

Ascension Talents
Yanfei’s Ascension Talents further enhance her damage potential. Her first ascension talent, Proviso, increases her Pyro Damage Bonus by 5% for each Scarlet Seal consumed in a Charged Attack. This effect lasts for six seconds and resets if another Charged Attack is used, making her attacks stronger when consistently using her mechanics. Her fourth ascension talent, Blazing Eye, causes her Charged Attacks to deal an additional instance of AoE Pyro damage equal to 80% of her Attack when they land a critical hit. This extra damage counts as Charged Attack damage, benefiting from her Scarlet Seal mechanics. Her passive talent, Encyclopedic Expertise, reveals the location of Liyue-exclusive resources on the mini-map, making exploration easier.

Scarlet Seals and Brilliance Mechanics
Scarlet Seals and Brilliance play a crucial role in Yanfei’s gameplay. Scarlet Seals are gained through Normal Attacks, Elemental Skill, and Elemental Burst, reducing stamina consumption and increasing the power of her Charged Attacks. Brilliance, gained from her Elemental Burst, ensures a steady supply of Scarlet Seals while boosting Charged Attack damage, making her rotation smoother. Properly managing these mechanics allows Yanfei to maintain a consistent flow of high-damage Pyro attacks.

Strengths and Weaknesses

Yanfei excels as a consistent Pyro damage dealer with strong elemental application. Since all her attacks deal Pyro damage, she is highly effective in reaction-based teams, particularly those focused on Vaporize, Melt, or Overload. As a catalyst user, her ranged attacks allow for safe positioning while still maintaining strong elemental synergy. Her Scarlet Seal mechanic reduces the stamina cost of Charged Attacks, allowing her to unleash powerful Pyro-infused hits without depleting stamina when managed properly. She does not require constellations to perform well, but they significantly improve her ease of use and survivability.

Despite her strengths, Yanfei has some weaknesses. Her overall damage output may be lower compared to top-tier Pyro DPS characters. She relies heavily on Charged Attacks, which consume a lot of stamina unless she has Scarlet Seals active, making her more vulnerable in prolonged fights. Energy management can also be an issue, as her Elemental Burst requires careful planning to sustain usage. Additionally, her Charged Attack animation is relatively long, leaving her susceptible to interruptions if not properly shielded or positioned.

How to Play Yanfei

Yanfei’s gameplay revolves around generating and consuming Scarlet Seals to maximize her Charged Attack damage. Since she is a catalyst user, all of her attacks inherently deal Pyro damage, making her an excellent on-field Pyro DPS for elemental reactions like Vaporize, Melt, Overload, and Burgeon. Her Normal Attacks generate Scarlet Seals, which reduce the stamina cost of her Charged Attacks and increase their damage and area of effect. She can hold up to three Scarlet Seals at base and four with Constellation 6. Managing these efficiently is key to maintaining consistent damage output, as consuming them at the right time allows for stronger and more frequent Charged Attacks without exhausting stamina too quickly.

Her Elemental Skill, Signed Edict, instantly grants the maximum number of Scarlet Seals and deals area-of-effect Pyro damage. This ability provides an immediate setup for a powerful Charged Attack and can be used mid-combo to maintain momentum in her damage rotation. Her Elemental Burst, Done Deal, deals AoE Pyro damage and also grants the maximum number of Scarlet Seals while applying Brilliance, a unique effect that periodically generates additional Scarlet Seals and increases the damage of her Charged Attacks. This makes her Elemental Burst essential for maintaining a steady flow of Scarlet Seals and ensuring her Charged Attacks remain powerful and frequent.

A standard rotation begins with activating off-field abilities from teammates to apply Hydro, Cryo, Electro, or Dendro for reactions. Yanfei then uses Normal Attacks to generate Scarlet Seals, followed by a Charged Attack to consume them for a strong Pyro hit. Using her Elemental Skill provides an instant Scarlet Seal boost, allowing for another Charged Attack with minimal stamina cost. When her Elemental Burst is available, activating it ensures a continuous supply of Scarlet Seals and boosts her Charged Attack damage. This rotation is particularly effective in Vaporize teams, where alternating two or three Normal Attacks followed by a Charged Attack allows her to trigger consistent and powerful Vaporize reactions.

One of Yanfei’s biggest challenges is her Charged Attack’s casting time, which leaves her vulnerable to enemy attacks. Without shields or interruption resistance, she can be easily staggered, disrupting her rotation and reducing her overall damage output. Her first constellation mitigates this issue by providing some resistance to interruption when she consumes Scarlet Seals, making it an important upgrade for smoother gameplay. Additionally, since she relies heavily on her Charged Attacks for damage, maintaining enough stamina can be a concern, especially in prolonged fights. Her Scarlet Seals help offset this by reducing stamina consumption, but players need to be mindful of when to attack, reposition, and dodge to avoid depleting her stamina pool too quickly.

Overall, Yanfei thrives as an on-field Pyro DPS who excels in reaction-based teams. Her ability to apply consistent Pyro damage through her Normal and Charged Attacks makes her particularly effective in Vaporize and Melt compositions. Properly managing her Scarlet Seals, timing her Elemental Skill and Burst, and ensuring stamina conservation are key to playing her efficiently. With proper team support and positioning, she can dish out reliable and sustained Pyro damage, making her a valuable option for players looking for a ranged Pyro DPS.
