Pros & Cons

Straightforward playstyle
Good matchup against flying units
- Noteworthy that she performs well against bosses (single-target oriented)
Flexible party compositions
- Mono-pyro comps are viable while Yoimiya has Vaporize and Overload comps possible as well.
Yun Jin is an optimal support for Yoimiya
- Yun Jin buffs Yoimiya's Normal Attacks and the overall value she brings is comparable to Bennett

Limited in optimized party options
- Most optimized comps want another co-star with Yoimiya, but Yoimiya doesn't offer unique advantages over other replacements
Generally wants a shielder
- While its not a strict requirement, the risk of getting interrupted matters a lot to her damage as well as her own safety.
Bad Skill/Burst multipliers (not worth levelling them up past 6)
Needing story-locked materials for growth hurts newer accounts
Limited by matchups (single target)

Skills

Firework Flare-Up

Normal Attack

Normal Attack
Performs up to 5 consecutive shots with a bow.

Charged Attack
Perform a more precise Aimed Shot with increased DMG.
While aiming, flames will accumulate on the arrowhead before being fired off as an attack. Has different effects based on how long the energy has been charged:

Charge Level 1: Fires off a flaming arrow that deals Pyro DMG.
Charge Level 2: Generates a maximum of 3 Kindling Arrows based on time spent charging, releasing them as part of this Aimed Shot. Kindling Arrows will home in on nearby opponents, dealing Pyro DMG on hit.

Plunging Attack
Fires off a shower of arrows in mid-air before falling and striking the ground, dealing AoE DMG upon impact.

Niwabi Fire-Dance

Elemental Skill

Yoimiya waves a sparkler and causes a ring of saltpeter to surround her.

Niwabi Enshou
During this time, arrows fired by Yoimiya's Normal Attack will be Blazing Arrows, and their DMG will be increased and converted to Pyro DMG.
During this time, Normal Attack: Firework Flare-Up will not generate Kindling Arrows at Charge Level 2.

This effect will deactivate when Yoimiya leaves the field.

Ryuukin Saxifrage

Elemental Burst

Yoimiya leaps into the air along with her original creation, the "Ryuukin Saxifrage," and fires forth blazing rockets bursting with surprises that deal AoE Pyro DMG and mark one of the hit opponents with Aurous Blaze.

Aurous Blaze
All Normal/Charged/Plunging Attacks, Elemental Skills, and Elemental Bursts by any party member other than Yoimiya that hit an opponent marked by Aurous Blaze will trigger an explosion, dealing AoE Pyro DMG.
When an opponent affected by Aurous Blaze is defeated before its duration expires, the effect will pass on to another nearby opponent, who will inherit the remaining duration.

One Aurous Blaze explosion can be triggered every 2s. When Yoimiya is down, Aurous Blaze effects created through her skills will be deactivated.

Builds

Pyro DPS Build

Yoimiya is a ranged, single target focused On-Field DPS character. She is very easy to learn and has access to many supports, such as Bennett and Yun in, who consistently help her out. She may not be the best Pyro DPS out there, but she indeed has some perks: range attacks hit flying enemies and there's no need to aim at all. On the other side, she struggles in multi-target situations and is very fragile, hence needs shielding.

Talent Priority

Normal Attack >> Skill = Burst
Yoimiya's damage comes from her Normal attack talent. Think of her Skill as a buff that infuses her attacks with Pyro. Her Burst while not great, still deals damage. Don't neglect the value of talent levels.

Stat Priority

Main stats: ATK/Pyro/Crit
Substats: Crit/Atk/EM
Yoimiya does benefit from EM but unless you are running Overload, your EM amplifies your damage which is also dependent on your Crit stats and attack.

Weapons

Yoimiya's personal weapon, and her best performing weapon.

Thundering Pulse

CRIT DMG

Rule By Thunder

Increases ATK by 20~40% and grants the might of the Thunder Emblem. At stack levels 1/2/3, the Thunder Emblem increases Normal Attack DMG by 12/24/40~24/48/80%. The character will obtain 1 stack of Thunder Emblem in each of the following scenarios: Normal Attack deals DMG (stack lasts 5s), casting Elemental Skill (stack lasts 10s); Energy is less than 100% (stack disappears when Energy is full). Each stack's duration is calculated independently.

Very competitive 5★ options if you can keep the passive up.

Polar Star

CRIT Rate

Daylight's Augury

Elemental Skill and Elemental Burst DMG increased by 12~24%. After a Normal Attack, Charged Attack, Elemental Skill or Elemental Burst hits an opponent, 1 stack of Ashen Nightstar will be gained for 12s. When 1/2/3/4 stacks of Ashen Nightstar are present, ATK is increased by 10/20/30/48~20/40/60/96%. The stack of Ashen Nightstar created by the Normal Attack, Charged Attack, Elemental Skill or Elemental Burst will be counted independently of the others.

Aqua Simulacra

CRIT DMG

The Cleansing Form

HP is increased by 16~32%. When there are opponents nearby, the DMG dealt by the wielder of this weapon is increased by 20~40%. This will take effect whether the character is on-field or not.

A very good weapon on Yoimiya, lots of stats and a good passive.

Skyward Harp

CRIT Rate

Echoing Ballad

Increases CRIT DMG by 20~40%. Hits have a 60~100% chance to inflict a small AoE attack, dealing 125% Physical ATK DMG. Can only occur once every 4~2s.

Weapon Variations

Yoimmiya's premier 4★ weapon. At R5 it can compete with 5★ bows.

Rust

ATK

Rapid Firing

Increases Normal Attack DMG by 40~80% but decreases Charged Attack DMG by 10%.

Good weapon as its passive offers some grouping potential to Yoimiya.

The Viridescent Hunt

CRIT Rate

Verdant Wind

Upon hit, Normal and Aimed Shot Attacks have a 50% chance to generate a Cyclone, which will continuously attract surrounding opponents, dealing 40~80% of ATK as DMG to these opponents every 0.5s for 4s. This effect can only occur once every 14~10s.

Yoimiya's F2P option. While the low base stats hurt, the passive and innate crit solidify itself as her best F2P option.

Slingshot

CRIT Rate

Slingshot

If a Normal or Charged Attack hits a target within 0.3s of being fired, increases DMG by 36~60%. Otherwise, decreases DMG by 10%.

Good stats but there are more competitive options limiting the value of Crescent's refines.

Prototype Crescent

ATK

Unreturning

Charged Attack hits on weak points increase Movement SPD by 10% and ATK by 36~72% for 10s.

Artifacts

Yoimiya has some synergy with this set as her Burst isn't a main part of her kit. It's viable on her and resin-efficient due to Emblem of Severed Fate.

Shimenawa's Reminiscence

2 ATK +18%.

4 When casting an Elemental Skill, if the character has 15 or more Energy, they lose 15 Energy and Normal/Charged/Plunging Attack DMG is increased by 50% for 10s. This effect will not trigger again during that duration.

Artifact Variations

General Purpose

The flexibility of Yoimiya's parties emphasizes the value of the 2pc combination. This combination is the jack of all trades only losing out in specific scenarios to other 4pc sets.

Crimson Witch of Flames

2 Pyro DMG Bonus +15%.

Gladiator's Finale

2 ATK +18%.

Reaction comps

Crimson Witch of Flames

2 Pyro DMG Bonus +15%.

4 Increases Overloaded and Burning DMG by 40%. Increases Vaporize and Melt DMG by 15%. Using an Elemental Skill increases the 2-Piece Set Bonus by 50% of its starting value for 10s. Max 3 stacks.

Niche sets

Used in Mono Pyro, not resin efficient.

Lavawalker

2 Pyro RES increased by 40%.

4 Increases DMG against opponents affected by Pyro by 35%.

Good option if you run a shield, but not resin efficient. Bonus points for matching aesthetic though.

Retracing Bolide

2 Increases Shield Strength by 35%.

4 While protected by a shield, gain an additional 40% Normal and Charged Attack DMG.

Can reach higher numbers but it isn't resin eficient and its effect is somehow related to your internet connection. High ping makes the 4pc effect almost useless as it triggers after the attack is already dealt.

Echoes of an Offering

2 ATK +18%.

4 When Normal Attacks hit opponents, there is a 36% chance that it will trigger Valley Rite, which will increase Normal Attack DMG by 70% of ATK.

This effect will be dispelled 0.05s after a Normal Attack deals DMG. If a Normal Attack fails to trigger Valley Rite, the odds of it triggering the next time will increase by 20%.

This trigger can occur once every 0.2s.
