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: Order, open Wednesday, Saturday, 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.

Short-Range Rapid Interdiction Fire

Chevreuse quickly shoulders her musket and fires at her opponent(s), dealing AoE Pyro DMG.

For a short duration after Chevreuse fires a shot, she will continuously restore HP to your active character on the field. The amount healed is based on her Max HP.

Hold to fire in a different fashion.

Hold

Enter Aiming Mode, locking a target in her sights to fire a precise interdiction shot. If Chevreuse has an Overcharged Ball, then she will fire the Overcharged Ball instead, dealing greater Pyro DMG in a larger area.

Chevreuse gains 1 Overcharged Ball every time a nearby character in the party triggers an Overloaded reaction, and can have up to 1 Overcharged Ball at a time.

Arkhe: Ousia

Periodically, after Chevreuse's Short-Range Rapid Interdiction Fire hits, a Surging Blade will be called forth that deals Ousia-aligned Pyro DMG.

"Actually, training regulations only had the phrase "interdiction fire," but the protagonist of this novel believes that even how stylish your terminology is can affect how motivated your troops are, which can put your opponents on the back foot right from the get-go... I think that's a good point, so I changed the regulations!"

Ring of Bursting Grenades

Chevreuse fires an explosive grenade at opponents with her musket, dealing AoE Pyro DMG. After the projectile hits, it will split into many secondary explosive shells.

The secondary explosive shells will burst after a short interval, dealing Pyro DMG to nearby opponents.

"Theoretically, a rectangular blast would be most efficient at destroying enemy formations. Unfortunately, the cross-section of an explosive shock wave is round, like most cakes. So, the secondary explosive shells can only be arranged like the fruit on a cake, forming a ring around the edge."

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: Polearms 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
Primordial Jade Winged-Spear	5★	674	CRIT Rate
Crimson Moon's Semblance	5★	674	CRIT Rate
Bloodsoaked Ruins	5★	674	CRIT Rate
Disaster and Remorse	5★	674	CRIT Rate
Staff of Homa	5★	608	CRIT DMG
Lumidouce Elegy	5★	608	CRIT Rate
Symphonist of Scents	5★	608	CRIT DMG
Fractured Halo	5★	608	CRIT DMG

Sets whose two-piece bonus raises this character’s Pyro damage or the stat they ascend into
Set	Two-piece	Four-piece
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.
Tenacity of the Millelith	HP +20%	When an Elemental Skill hits an opponent, the ATK of all nearby party members is increased by 20% and their Shield Strength is increased by 30% for 3s. This effect can be triggered once every 0.5s. This effect can still be triggered even when the character who is using this artifact set is not on the field.
Vourukasha's Glow	HP +20%	Elemental Skill and Elemental Burst DMG will be increased by 10%. After the equipping character takes DMG, the aforementioned DMG Bonus is increased by 80% for 5s. This effect increase can have 5 stacks. The duration of each stack is counted independently. These effects can be triggered even when the equipping character is not on the field.

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
