Yoimiya Guide and Best Builds for Genshin Impact

Strengths

• Strong single-target damage.
• Simple and easy playstyle.
• No required Constellations.
• Easy weapon choices for F2P.

Weaknesses

• Damage being reliant on her Elemental Skill.
• High competition among Pyro carries.
• Very little AoE damage on her own.
• Cannot hit targets close to the ground at close range.

Yoimiya's primary method to deal damage is through Normal Attack: Firework Flare-Up during her Elemental Skill Niwabi Fire-Dance. This infuses her attacks with Pyro while applying a damage multiplier on top. Next to that, we utilize her together with a lot of off-field DPS to apply Hydro or Electro.

Thundering Pulse is the weapon that released with Yoimiya and is her best weapon as she is able to utilize the entire passive effect. Its effects are very easy to maintain on Yoimiya, which buffs her Normal Attack: Firework Flare-Up.

Out of the rest of the weapons that Yoimiya can utilize, it depends on the refinement.

• Slingshot at R5 is not only very easy to get as it is a 3-star weapon, but its effect is easy to trigger as long as you do not stand too far away. The range is pretty lenient so do not worry too much about it.
• Aqua Simulacra is generally slightly better than Slingshot R5 depending on your team, but is outperformed by Rust R5.
• Rust is a 4-star weapon, so might take some luck to get to R5. Team comps that buffs Yoimiya's ATK can make Slingshot R5 outperform Rust as well. This is due to the way Flat damage bonuses work in tangent with ATK % stats, as flat bonuses are added in after ATK %. This means that with high enough increases, the CRIT Rate substat on Slingshot overtakes the ATK % substat on Rust.

The Artifact choices depends on your team composition.

• Shimenawa's Reminiscence is very good on Yoimiya and in most cases, this will be the set you are using. The reason for this is that the vast majority of Yoimiya's damage comes from her Normal Attack: Firework Flare-Up during Niwabi Fire-Dance. She also does not really focus on using her burst, so the energy used to trigger the 4-piece effect does not matter.
• On the other hand, if your team composition is built around triggering a lot of reactions (like Vaporize and Overload), Crimson Witch of Flames can be better. This works in conjunction with her burst as well, as you would want to snapshot the ATK % buff from her 4th Ascension Passive Summer Night's Dawn. In these teams, Yoimiya's personal damage takes a smaller role over the reactions, making the ATK % matter more, while Shimenawa's Reminiscence will hurt your overall uptime of your burst.

Her playstyle is very simple. Generally, her damage comes from Normal Attack: Firework Flare-Up while Niwabi Fire-Dance is up. In the mean time you swap to your off-field characters to recharge their bursts and get ready for another rotation.

Yoimiya uses the standard ICD for Elemental Application, meaning that her attacks can only apply Pyro once every 2.5s or every 3rd hit (whichever happens first). Her Normal Attack consists of 7 hits over 5 attacks, where the first and 4th attack has 2 hits. This means that you will apply Pyro on the first hit with the first Normal Attack (N1-1), the third Normal Attack (N3) and on the fifth Normal Attack (N5) as long as you do not move or get interrupted. This is important to play around, since N3 and N5 are your hardest hitting Normal Attacks! Furthermore, if you run with a Vaporize comp, you want Vaporize to happen on the hardest hitting attacks since Vaporize is a straight DMG modifier to the attack.

This is why you often want to have a character in your party who can shield you. This provides you with interruption RES, while also allowing you to take the occasional hit.

Yoimiya's best teams usually revolve around triggering Vaporize and/or Overload. Vaporize works really well, since she converts her Normal Attack damage into Pyro on her own and one of Overloads main issues is solved since Yoimiya is ranged. Outside of that, shield characters are more or less a requirement to have, if you want to play Yoimiya optimally. Below are some examples on the teams you would see her in.

These Vaporize teams utilizes Xingqiu's or Yelan's Burst to trigger Hydro in-between Yoimiya's Normal Attack: Firework Flare-Up to in turn trigger Vaporize. It is very important to not interrupt your attack rotation, as it will misalign your Pyro application. This means that either your Hydro Application triggers Vaporize or one of your weaker Normal Attacks triggering it, leading to a significant loss in damage. This is why we bring along Zhongli or Thoma. Their shield will help you avoid being interrupted during your Normal Attacks if you get hit by something.

This team is very flexible. The idea behind this team is to have at least 1 Hydro and 1 Electro character. The last character in the team is a flex slot, and can be filled in by any of the characters listed. The reason why most Overload have issues is due to it knocking back enemies, however that is not an issue for Yoimiya as she has quite a lot of range to counteract the knockback. You can combine the teams to have both Hydro and Electro in the team. The potential list of characters you can flex in is a lot longer than what is shown above, however those 3 are the most common. You do not need to use a flex, and can instead slot in another Hydro or Electro if you feel like it. This team will benefit from having more Elemental Mastery, however you do not need to beeline for it. This team would want to use Crimson Witch of Flames.

This setup runs with Bennett for the ATK increase from his Fantastic Voyage. From there, you can add in Yun Jin or Albedo for more damage support (or both). There are more examples of who you can slot in as your 4th, however it is preferred to slot in someone who can shield. An example team would be Yoimiya, Bennett, Yun Jin, and Zhongli.

This can also be a variation on the Vaporize team comp further up, where you add in an Anemo character, with the Viridescent Venerer set, to shred Pyro RES before swapping back to Yoimiya. You can flex out Bennett for Thoma with this setup, to provide shields and the 4th character slot can be filled by a Hydro character.

With this team, we are sorely focusing on Yoimiya's Normal Attack DMG and Overload DMG. Chevreuse is a hard requirement, while Fischl is one of the best characters for Off-field Electro application. Whether you use Bennett or Beidou depends on what you like the most. Bennett provides more damage to Yoimiya's attacks and pairs well with Chevreuse in terms of healing, while Beidou will provide Yoimiya with Interrupt RES and reduces the damage you take through Beidou's Burst. Beidou's constellations can also provide a decent shield on top. Yoimiya furthermore compliments Beidou through her Ascension passives, as Stormbreaker snapshots at when cast.
