In the vibrant world of Teyvat, Yoimiya, the effervescent owner of Naganohara Fireworks in Inazuma, has long been celebrated as the "Queen of the Summer Festival." Her ability to weave the hopes and dreams of the people into her spectacular pyrotechnic displays has made her not just a beloved figure but also one of the most formidable Pyro DPS characters in Genshin Impact. By 2026, her position as a premier on-field damage dealer remains unchallenged, perfect for players who relish a straightforward, high-impact playstyle focused on unleashing a barrage of fiery arrows. Her unique kit allows her to not only decimate foes with ease but also empower her allies, making her a versatile cornerstone for many team compositions.

🔥 Yoimiya's Optimal Builds & Artifact Sets

As the central Pyro damage dealer, constructing Yoimiya requires a meticulous focus on stats that amplify her explosive potential. Players should aim for a harmonious blend of ATK, Crit Rate, and Crit Damage, supplemented by Pyro DMG Bonus. Secondary stats like Elemental Mastery and Energy Recharge also provide significant value. The choice of artifact set is profoundly influenced by her teammates, as it determines whether to maximize her personal devastating output or enhance the team's overall synergy.

The Signature Set: 4-Piece Shimenawa's Reminiscence

This set is tailor-made for Yoimiya's primary damage source: her Normal Attacks. It grants an 18% ATK bonus and a massive 50% increase to Normal, Charged, and Plunging Attack DMG for 10 seconds upon using her Elemental Skill. This ignites her assault, transforming her arrows into a blazing torrent. However, this power comes at a cost: 15 Energy, which can delay her Burst. Since her Burst provides a valuable team-wide ATK buff, using Shimenawa's may elevate her personal damage at the expense of team utility. This can be mitigated by pairing her with supports like Yelan or Yun Jin, whose damage scales independently of ATK.

The Reactive Set: 4-Piece Crimson Witch of Flames

For teams focusing on elemental reactions like Vaporize or Overload, the Crimson Witch set is exceptionally potent. It provides a 15% Pyro DMG Bonus and enhances reaction damage significantly. Its unique mechanic increases the Pyro DMG bonus further with each Elemental Skill use. This set is ideal when running with allies like Xingqiu or Beidou, as it allows them to fully benefit from Yoimiya's Burst ATK buff while she triggers powerful reactions.

Stat Priority for Both Sets:

Artifact Piece Main Stat Priority Substats Priority
Sands ATK% Crit Rate / Crit DMG > Elemental Mastery > Energy Recharge
Goblet Pyro DMG Bonus Crit Rate / Crit DMG > ATK% > Elemental Mastery
Circlet Crit Rate or Crit DMG The other Crit stat > ATK% > Elemental Mastery

The golden rule is maintaining a Crit Rate to Crit DMG ratio close to 1:2 for consistent, high-impact critical hits.

🏹 Yoimiya's Premier Weapon Arsenal

Choosing the right bow is crucial for unlocking Yoimiya's full pyrotechnic prowess. Weapons that offer Crit DMG are typically her top choices, though those with high ATK% or Crit Rate also synergize flawlessly with her kit. Remarkably, she boasts excellent accessible options, proving that devastating power isn't locked behind rarity.

⭐⭐⭐⭐⭐ 5-Star Divine Weapons

Thundering Pulse: The Undisputed Champion

This bow is Yoimiya's biS (best in slot). Its massive Crit DMG substat and skill that boosts ATK and Normal Attack DMG are perfectly aligned with her rotation. By opening with her Burst and then using her Skill, she can effortlessly gain all three stacks of its Thunder Emblem, unleashing a cataclysmic salvo of empowered attacks.

Aqua Simulacra: The High-Risk, High-Reward Option

While offering impressive Crit DMG, its passive requires Yoimiya to stay near enemies—a challenge given her inherently mobile attack pattern that often steps her back. To utilize this weapon effectively, a reliable shielder like Zhongli is almost mandatory to keep her within the damage bonus zone.

⭐⭐⭐⭐ 4-Star Gacha Gem: Rust

At high refinements (R4-R5), Rust becomes a monstrously powerful option. Its skill dramatically increases Normal Attack DMG—Yoimiya's main source of destructive force. In this refined state, it can surpass the performance of several 5-star weapons, making it a top-tier prize for dedicated players.

⭐⭐⭐ 3-Star F2P Marvel: Slingshot

Do not underestimate this accessible weapon! At high refinement, the Slingshot is a formidable contender. Its Crit Rate substat and conditional damage bonus make it shockingly effective, especially when supported by a shielder and ATK buffers like Bennett or Yun Jin. It stands as a testament that strategic builds can triumph over raw rarity.

👥 Yoimiya's Supreme Team Compositions

Yoimiya excels in teams built around amplifying her Pyro damage through reactions or pure elemental power. The best strategies involve pairing her with strong off-field supports who can apply elements or buffs while she remains on the field, orchestrating the fireworks display. Here are the premier team archetypes:

  • Vaporize Teams (Yoimiya's Peak Damage): These teams focus on triggering the Vaporize reaction for massive damage multipliers.

  • Core Example: Yoimiya + Yelan/Xingqiu (Hydro applicator) + Zhongli (Shielder) + Yun Jin/Bennett (Buffer).

  • How it works: Yoimiya's Pyro-infused Normal Attacks consistently trigger Vaporize on the Hydro applied by Yelan or Xingqiu's abilities, leading to explosive single-target damage.

  • Overload & Overvape Teams (Crowd Control & AoE): These utilize the Electro-charged and Overload reactions for chaotic area-of-effect damage.

  • Core Example: Yoimiya + Fischl/Beidou (Electro applicator) + Yelan/Xingqiu + Bennett.

  • How it works: Yoimiya triggers both Overload (Pyro+Electro) and Vaporize (Pyro+Hydro) simultaneously ("Overvape"), creating a spectacle of constant elemental eruptions that juggle and damage groups of enemies.

  • Mono-Pyro Teams (Raw Power & Swirl): These teams forego intricate reactions for sheer Pyro dominance and Swirl support.

  • Core Example: Yoimiya + Xiangling (Off-field Pyro) + Kazuha/Sucrose (Anemo grouper/VV shred) + Bennett (Battery/Healer/Buffer).

  • How it works: This composition focuses on overwhelming Pyro application, using Anemo characters with the Viridescent Venerer set to reduce enemy Pyro resistance and boost Yoimiya's damage directly. Bennett provides an immense ATK buff and healing, creating a self-sustaining inferno.

By mastering her builds, selecting the ideal weapon, and assembling a synergistic team, players can fully unleash the radiant potential of Yoimiya, the Queen of the Summer Festival, ensuring her fireworks display is always a devastatingly beautiful sight on the battlefield of Teyvat.
