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: Gold, 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.

Talents

Seal of Approval

Normal Attack

Shoots fireballs that deal up to three counts of Pyro DMG.

When Yanfei's Normal Attacks hit enemies, they will grant her a single Scarlet Seal. Yanfei may possess a maximum of 3 Scarlet Seals, and each time this effect is triggered, the duration of currently possessed Scarlet Seals will refresh.

Each Scarlet Seal will decrease Yanfei's Stamina consumption and will disappear when she leaves the field.

Charged Attack

Consumes Stamina and all Scarlet Seals before dealing AoE Pyro DMG to opponents after a short casting time.

This Charged Attack's AoE and DMG will increase according to the amount of Scarlet Seals consumed.

Plunging Attack

Gathering the power of Pyro, Yanfei plunges towards the ground from mid-air, damaging all opponents in her path. Deals AoE Pyro DMG upon impact with the ground.

Signed Edict

Summons blistering flames that deal AoE Pyro DMG.

Opponents hit by the flames will grant Yanfei the maximum number of Scarlet Seals.

Apart from their legal uses, Yanfei's seals also come with her customized additional terms and conditions. Well, it's not as if the Ministry of Civil Affairs can change the laws of nature.

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: Catalysts 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
Crane's Echoing Call	5★	741	ATK%
Angelos' Heptades	5★	741	ATK%
Skyward Atlas	5★	674	ATK%
Tulaytullah's Remembrance	5★	674	CRIT DMG
Cashflow Supervision	5★	674	CRIT Rate
Vivid Notions	5★	674	CRIT DMG
Lost Prayer to the Sacred Winds	5★	608	CRIT Rate
Memory of Dust	5★	608	ATK%

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.

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
