What it costs to finish this character

1,350

resin, level 1 → 90 and all three talents to 10

2,072,500

mora

days at a minimum, if you spend nothing else

Ascension alone: 760 resin (boss drops only) · talents alone: 590 resin.

Talent domain: Transience, open Monday, Thursday, Sunday.

A Crown of Insight is needed for the tenth level of each talent, and crowns are not farmable at any resin price — they come from events.

Materials and mora above are exact, straight from the game’s own tables. The resin figure and the day count divide by an average drop per run, which the game does not publish — they are a community-measured mean, not a promise.

Talents

Firework Flare-Up

Normal Attack

Performs up to 5 consecutive shots with a bow.

Charged Attack

Performs 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

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.

"Niwabi" is a form of incense firework created by Yoimiya herself. Its ability to be lit without any prior training or preparation has made it a real hit. After many fire-related incidents, the Tenryou Commission ordered the use of "Niwabi" banned, but small, bright sparks can often still be seen springing up at night. If seen from above, they look almost like little twinkling stars.

Ryuukin Saxifrage

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.

Fireworks are man-made starlight, comets fired into the sky. Though they last for but an instant, the memory of their brilliance shall surely live on.

Weapons and artifacts

UNSURE This is not a tier list and not community guidance — this product has neither. It is a mechanical shortlist, and the rule is printed so you can check it: Bows of 4★ and above whose secondary stat is one this character’s ascension stat scales with, ordered by base attack at level 90. Weapon passives are not weighed, because a passive is an effect and not a number.

Weapons of the right type and stat
Weapon	Rarity	Base ATK at 90	Secondary stat
Skyward Harp	5★	674	CRIT Rate
The Daybreak Chronicles	5★	674	CRIT DMG
Amos' Bow	5★	608	ATK%
Polar Star	5★	608	CRIT Rate
Thundering Pulse	5★	608	CRIT DMG
The First Great Magic	5★	608	CRIT DMG
Astral Vulture's Crimson Plumage	5★	608	CRIT DMG
Aqua Simulacra	5★	542	CRIT DMG

Sets whose two-piece bonus raises this character’s Pyro damage or the stat they ascend into
Set	Two-piece	Four-piece
Berserker	CRIT Rate +12%	When HP is below 70%, CRIT Rate increases by an additional 24%.
Crimson Witch of Flames	Pyro DMG Bonus +15%	Increases Overloaded, Burning, and Burgeon DMG by 40%. Increases Vaporize and Melt DMG by 15%. Using Elemental Skill increases the 2-Piece Set Bonus by 50% of its starting value for 10s. Max 3 stacks.

To turn this into a real recommendation section, add a build dataset — per character, the weapons and sets a community source actually recommends, with the rotation each assumes. Nothing in the game’s published data contains that judgement, and a ranking invented here would be indistinguishable from a researched one, which is why there is not one.

Teams

To build a team section, add team data. Which characters go together is judgement about rotations, energy and shielding that this product does not receive and will not guess at.

What is published is the reaction chart. Pyro takes part in:

Vaporize with Hydro
Melt with Cryo
Overloaded with Electro
Burning with Dendro
