The Definitive Build & Analysis

Rarity	(5-Star)
Element	Pyro
Weapon	Bow
Best Role	Normal Attack Main DPS
CV Priority	CRIT > ATK% > EM
Tier	A (Single Target Boss Killer)

Yoimiya is the Queen of the Summer Festival and a premiere single-target Pyro DPS. Known for her rapid-fire "machine gun" playstyle, she excels at taking down bosses (like the Thunder Manifestation) where auto-aim is king. She requires a shielder to ensure her attack string isn't interrupted.

Quick Guide (TL;DR)

If you don't have time for the math, here is the cheat sheet.

Best Artifact: 4pc Shimenawa's Reminiscence (Standard BiS).
Alt Artifact: 4pc Crimson Witch (Vape) or 4pc Echoes of an Offering (Low Ping Only).
Best Weapon: Thundering Pulse (Signature) or Rust (R5).
F2P Weapon: Slingshot (R5 - 3⭐ God Weapon) or Hamayumi.
Main Stats: SANDS: ATK% or EM | GOBLET: Pyro DMG | CIRCLET: CRIT.
Talent Priority: Normal Attack > Elemental Skill > Elemental Burst.
Top Team: Yoimiya + Yelan + Zhongli + Bennett.

Pro Tip: Do not interrupt your combo! Yoimiya's highest damage multipliers are on her 3rd and 5th shots. Dashing resets the combo string. Use a shield (Zhongli/Layla) so you can stand still and finish the N5 string.

Talent Breakdown & Mechanics

Normal Attack: Firework Flare-Up

5-Hit String: Yoimiya fires 5 shots (N1 to N5). The damage backloads heavily, with the 5th shot dealing the most damage.
ICD (Internal Cooldown): Yoimiya follows standard ICD. This means she Vaporizes on her 1st, 3rd, and 5th hits (N1, N3, N5). Interrupting the string ruins this vape pattern.

Elemental Skill: Niwabi Fire-Dance

Infusion: Converts Normal Attacks to Pyro DMG for 10s. Increases the DMG of Normal Attacks.
Particle Generation: She generates particles while hitting enemies during this stance.
Mechanic: While active, you cannot use Charged Attacks (Kindling Arrows). Just spam the Attack button.

Elemental Burst: Ryuukin Saxifrage

Cost: 60 Energy | Cooldown: 15s
Aurous Blaze: Marks an enemy. When *other* party members hit the mark, it explodes dealing AoE Pyro DMG.
Usage: If using 4pc Shimenawa, you generally do not use this burst as the artifact set drains your energy. If using Crimson Witch, cast this at the start of rotation.

Talent Priority Order:

Normal Attack (Level 10) - This is the multiplier she uses.
Elemental Skill (Level 9) - Buffs the NA multiplier.
Elemental Burst (Level 1-6) - Often unused in optimal play.

Stat Requirements & ER Thresholds

Yoimiya's ER requirements are unique: she generally avoids ER if using Shimenawa's Reminiscence.

Build Type	EM Goal (Vape)	ER Requirement
Shimenawa (Standard)	100+	0% (Do not build ER)
Crimson Witch (Bursting)	100+	130% - 140%
Mono Pyro / Chevreuse	0	0%

Substat Priority:

CRIT Rate / CRIT DMG (Target 75/150+ for consistency)
Elemental Mastery (Vital for Vaporize teams)
ATK%
Energy Recharge (Avoid on Shimenawa)

Best Artifacts Comparison

Set Name	Role	Reasoning
4pc Shimenawa's Reminiscence	General BiS	Consumes 15 Energy to boost Normal Attack DMG by 50%. Perfectly aligns with her E-spam playstyle. Farming efficient (Momiji-Dyed Court).
4pc Crimson Witch of Flames	Vaporize	Competitive if you want to use her Burst. Slightly better for Reaction DMG but generally less ATK stats.
4pc Echoes of an Offering	Low Ping	RNG based. Only use if your ping is < 50ms, otherwise server lag causes the set effect to fail.

Weapon Rankings

Weapon	Type	Performance	Description
Thundering Pulse	CRIT DMG	S+	Signature. Massive Crit DMG and Normal Attack buffs based on energy drain (works perfectly with Shimenawa).
Rust (R5)	ATK%	S	The "4-Star Signature." At R5, it increases Normal Attack DMG by 80%. It outperforms most R1 5-star bows (like Skyward Harp/Amos).
Slingshot (R5)	CRIT Rate	A+ (F2P)	3-Star weapon. Passive gives 60% DMG bonus. If paired with Bennett/Yun Jin to fix the low Base ATK, it rivals Rust R3.
Aqua Simulacra	CRIT DMG	S	Great stat stick (88% CD), but you must play close range to trigger the passive.

Constellation Value

Yoimiya is a complete unit at C0. Her constellations are steady but minor DPS increases.

C1: Agate Ryuukin - (Minor) Extends Burst duration and buffs ATK when an enemy marked by Burst is defeated. Weak if using Shimenawa.
C2: A Procession of Bonfires - (Good) When Yoimiya scores a CRIT with Pyro DMG, she gains 25% Pyro DMG Bonus. Always active since she hits fast.
C6: Naganohara Meteor Swarm - (Machine Gun) During Skill, normal attacks have a 50% chance to fire an extra arrow dealing 60% DMG. Massive damage increase and very fun.

Verdict: Stop at C0 or go for C2. Only whales need C6.

Top Team Compositions

1. Vaporize Hypercarry

Main DPS: Yoimiya
Hydro: Yelan / Xingqiu
Shield: Zhongli / Layla
Buffer: Bennett / Yun Jin

Why it works: The classic team. Yelan provides Hydro application and a ramping DMG buff. Zhongli ensures Yoimiya doesn't get interrupted so she can hit her N5 vape. Yun Jin (C6) is a strong alternative to Bennett for Attack Speed.

2. Chevreuse Overload

Main DPS: Yoimiya
Support: Chevreuse (C6 preferred)
Electro: Fischl (C6)
Electro: Beidou / Yae Miko

Why it works: Yoimiya is ranged, so the "knockback" from Overload doesn't hurt her DPS like it does for Hu Tao. Chevreuse provides massive RES shred and buffs without needing complex swirl setups.

Rotations & Combos

Standard Rotation:
Zhongli Hold E > Yelan E Q > Bennett E Q > Yoimiya E -> Spam Normal Attack

Combo Rule:
Spam standard attacks until the infusion ends (approx 3 full N5 strings). Do not Burst if using Shimenawa until after your E duration ends, or don't burst at all.

Frequently Asked Questions

Is Rust R5 really better than Skyward Harp?
Yes. The 80% Normal Attack DMG bonus from Rust R5 is so massive for Yoimiya that it generally beats low-refinement 5-star stat sticks unless your CRIT ratio is terrible.

Yun Jin vs. Bennett?
Bennett is generally better for AoE healing/buffing, but Yun Jin (especially C6) provides ATK Speed which Yoimiya loves. Using both together creates a hyper-carry monster.
