The Definitive Build & Analysis

Rarity	(4-Star)
Element	Pyro
Weapon	Claymore
Best Role	Physical Burst DPS / Shield Support
CV Priority	CRIT DMG > ATK > DEF > ER
Tier	B (Niche Physical Support)

Xinyan is a unique character who suffers from "Split Scaling": she needs DEF for her Shield but ATK for her Damage. However, at C2, she guarantees a Critical Hit on her Burst, allowing for a specialized "Nuke" playstyle that ignores Crit Rate entirely.

Quick Guide (TL;DR)

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

Best Artifact (DPS): 2pc Pale Flame + 2pc Bloodstained Chivalry.
Best Artifact (Support): 4pc Tenacity of the Millelith.
Best Weapon: Redhorn Stonethresher (BiS for C6) or Wolf's Gravestone.
F2P Weapon: Snow-Tombed Starsilver (DPS) or Whiteblind (Shield).
Main Stats (DPS): SANDS: ATK% | GOBLET: Phys DMG | CIRCLET: CRIT DMG.
Talent Priority: Elemental Burst > Normal Attack > Elemental Skill.
Top Team: Xinyan + Eula + Rosaria + Bennett (Physical Nuke).

Pro Tip: If you have C2 Xinyan, you do NOT need Crit Rate for her Burst build. Her C2 grants 100% Crit Rate to the Physical portion of her burst. Stack purely CRIT DMG.

Talent Breakdown & Mechanics

Elemental Skill: Sweeping Fervor

Shield Mechanism: Deals Pyro DMG and creates a shield based on DEF.
Shield Levels: Hitting 0/1 enemies = Lvl 1/2 Shield. Hitting 2+ enemies = Lvl 3 Shield (Rave). The Lvl 3 Shield pulses Pyro DMG continuously.
Ascension 2 Passive: Reduces the requirement to: Hitting 1 enemy = Lvl 2; Hitting 2+ = Lvl 3. (Still buggy/hard to hit).

Elemental Burst: Riff Revolution

Cost: 60 Energy | Cooldown: 15s
Physical Nuke: Deals one massive instance of Physical DMG (not Pyro). Then deals small instances of Pyro DMG.
C2 Synergy: At C2, this skill's Physical DMG has 100% Crit Rate. This allows you to build 300% Crit DMG without needing any Crit Rate on artifacts.

Passive: ...Now That's Rock 'N' Roll!

Physical Buff: Characters shielded by Sweeping Fervor gain a 15% Physical DMG Bonus. This makes her a solid support for Eula, Razor, or Freminet.

Talent Priority Order:

Elemental Burst (Level 9) - For the Nuke.
Normal Attack (Level 8) - If C6 Spin-to-Win.
Elemental Skill (Level 1/6) - Scale only if building Shield Support.

Stat Requirements & ER Thresholds

You must choose ONE path. Do not try to build hybrid (Split Scaling will ruin you).

Build Path	Stat Priority	ER Requirement
Physical Burst (C2+)	CRIT DMG > ATK > ER	130% - 150%
Shield Support (C0-C6)	DEF% > ER	200%+
Spin-to-Win (C6)	DEF% > CRIT > ATK	120%

Substat Priority (Burst DPS):

CRIT DMG (Go all in. Ignore Crit Rate.)
ATK% (Burst scales on ATK)
Energy Recharge
Flat ATK

Best Artifacts Comparison

Set Name	Role	Reasoning
2pc Bloodstained / 2pc Pale Flame	Burst DPS	Provides a flat +50% Physical DMG Bonus. Best for maximizing the Burst nuke.
4pc Tenacity of the Millelith	Shield Support	Her Lvl 3 Shield pulses, keeping the 20% ATK buff active for the team. Requires getting the Lvl 3 shield consistently (C2 helps).
4pc Emblem of Severed Fate	Hybrid	Good for Burst damage if you struggle with ER, but 2pc/2pc Phys is usually stronger for pure damage.

Weapon Rankings

Weapon	Type	Performance	Description
Redhorn Stonethresher	CRIT DMG	S+ (C6)	With C6 (DEF to ATK conversion), this weapon is insane. Massive Crit DMG stat stick.
Wolf's Gravestone	ATK%	S	Best for Support/Burst hybrid. Buffs team ATK significantly.
Whiteblind (R5)	DEF%	S (C6/Shield)	Craftable. Best for Shield Support and C6 Spin DPS. Useless for C0-C5 Burst DPS.
Snow-Tombed Starsilver	Phys DMG	A (F2P)	Dragonspine freebie. Solid for Physical Burst DPS builds.

Constellation Value

Xinyan changes dramatically at C2 and C6.

C2: Impromptu Opening - (The Fix) Burst Physical DMG has 100% Crit Rate. A Lvl 3 Shield is automatically formed when casting Burst. This allows you to ignore Crit Rate stats entirely and focus on Crit DMG.
C4: Wildfire Rhythm - (Support) Skill swing reduces enemy Physical RES by 15%. Excellent for supporting Eula.
C6: Rockin' in a Flaming World - (Spin-to-Win) Decreases Stamina Consumption of Charged Attacks by 30%. Converts 50% of DEF to ATK during Charged Attacks. Enables the "Spinner" playstyle.

Verdict: C2 is mandatory for her Burst playstyle. C4 is key for support.

Top Team Compositions

1. Eula Support

Main DPS: Eula
Support: Xinyan (C4 + Tenacity)
Electro: Raiden / Fischl
Battery: Rosaria / Diona

Why it works: Xinyan provides Pyro for Superconduct/Melt (rarely), Shielding, 15% Phys DMG Bonus (Passive), and 15% Phys RES Shred (C4). She consolidates multiple buffs.

2. Physical Nuke (Quickswap)

Burst DPS: Xinyan (C2)
Buffer: Bennett
Sub-DPS: Rosaria (C6 shreds Phys)
Electro: Lisa (A4 shreds DEF) / Raiden

Why it works: Bennett buffs ATK. Lisa/Rosaria apply Superconduct and shred resistance. Xinyan steps in, presses Q for a guaranteed crit nuke (50k-100k+), and swaps out.

Rotations & Combos

Support Rotation:
Electro App > Cryo App > Xinyan E (Shred) > Main DPS Burst

Burst Nuke (C2):
Bennett Q > Rosaria Q > Lisa Q > Xinyan Q

Frequently Asked Questions

Why is her shield so weak?
Her shield scales on DEF, but to deal damage, she needs ATK/Crit. This "Split Scaling" means you usually have to choose: strong shield and no damage, or good damage and paper shield.

Is she better than Zhongli/Thoma?
No. She is a niche pick for Physical teams specifically. Thoma is better for Burgeon/Pyro setups, and Zhongli is the universal shield god.
