Best Role	Normal Attack Buffer
Stat Priority	DEF% > ER > CRIT Rate (Favonius)
Tier	A (For Yoimiya/Ayato)

Yun Jin is the director of the Yun-Han Opera Troupe and a specialist support for characters who rely on Normal Attacks. Unlike other Geo supports, she thrives in "Rainbow" teams with diverse elements, using her Defense to add massive flat damage to her teammates' strikes.

Pros

Massive Flat DMG buff for Normal Attacks (Yoimiya/Ayato/Noelle).
C6 provides rare 12% Attack Speed buff.
Flexible team building (Passive rewards varied elements).
Easy to build (DEF% artifacts).
Skill has a fun Parry mechanic that generates decent particles.

Cons

Buff has a quota (30 hits). fast attackers consume it quickly.
Useless for Charged Attack DPS (Hu Tao/Ganyu).
High Energy Recharge requirements.
Lack of DEF% Polearm options (except Deathmatch BP).

Quick Guide (TL;DR)

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

Best Artifact: 4pc Husk of Opulent Dreams (BiS - DEF Stacking).
Alt Artifact: 4pc Noblesse Oblige (If team needs ATK%).
Best Weapon: Favonius Lance (Mandatory for Battery/ER).
Alt Weapon: Engulfing Lightning (ER Stat Stick).
F2P Weapon: Prototype Starglitter (Craftable ER).
Main Stats: SANDS: DEF% or ER | GOBLET: DEF% | CIRCLET: DEF% or CRIT Rate.
Talent Priority: Elemental Burst (Q) > Elemental Skill (E) > Normal Attack (Ignore).
Top Team: Yun Jin + Yoimiya + Yelan + Zhongli.

Pro Tip: Parry Master: Yun Jin's Skill can be tapped or held. Holding it creates a shield that charges up. If you time the press exactly when an enemy hits you (Perfect Parry), you instantly gain max charge without waiting, dealing max damage and generating max particles immediately.

Talent Breakdown & Mechanics

Elemental Skill: Opening Flourish

Parry Mechanic: Tap E for an instant strike. Hold E to charge a shield.
Perfect Counter: Releasing the hold exactly when hit deals max damage.
Energy: Generates particles upon hit. Essential for battery.

Elemental Burst: Cliffbreaker's Banner

Cost: 60 Energy | Cooldown: 15s
Flying Cloud Flag Formation: Grants a Flat DMG Bonus to all party members' Normal Attacks.
Scaling: The bonus damage is based on Yun Jin's current DEF. This is why you stack DEF on her.
Trigger Quota: Each character has a quota of 30 hits. In AoE, hitting multiple enemies consumes multiple quota stacks instantly.

Passive: Breaking Conventions

Rainbow Synergy: The Normal Attack DMG Bonus is further increased by 2.5% / 5% / 7.5% / 11.5% of Yun Jin's DEF for having 1/2/3/4 different elemental types in the party.
Implication: Yun Jin works best in teams with varied elements (e.g., Pyro + Hydro + Geo + Anemo), unlike Gorou who wants Mono Geo.

Talent Priority Order:

Elemental Burst (Level 10) - The source of her buff.
Elemental Skill (Level 8) - Particle generation and shield.
Normal Attack (Level 1) - Ignore.

Stat Requirements & ER Thresholds

Yun Jin is stat hungry. She needs high DEF for buffs but critical ER to function.

Team Context	Weapon	ER Requirement
Solo Geo (Yoimiya Team)	Favonius Lance	180% - 200%
Solo Geo (Yoimiya Team)	Non-ER Weapon	220% - 240%
Double Geo (w/ Zhongli)	Favonius Lance	160% - 180%

Substat Priority:

Energy Recharge (Until burst is consistent - Priority #1)
DEF% (Maximizes Buff)
CRIT Rate (Only to trigger Favonius Lance)
Flat DEF

Best Artifacts Comparison

Set Name	Role	Reasoning
4pc Husk of Opulent Dreams	BiS	Provides massive DEF (54% at max stacks). Since Yun Jin is off-field, she maintains the stacks easily. Best for maximizing her buff.
4pc Noblesse Oblige	Team ATK	If no one else in the team has Noblesse, this is a viable alternative to buff the carry's ATK% alongside Flat DMG.
2pc Husk / 2pc Emblem	ER Balance	If you can't reach ER requirements with 4pc Husk, mixing 2pc Emblem (20% ER) helps consistency.

Weapon Rankings

Weapon	Type	Performance	Notes
Favonius Lance	ER%	S+	Solves her ER issues and batteries the main DPS. The clear winner for almost all builds.
Engulfing Lightning	ER%	S	Massive ER stat stick. Luxury option if Raiden doesn't need it.
Prototype Starglitter	ER%	A (F2P)	Craftable. Good ER stat. Passive is useless, but it helps getting burst back.
Deathmatch	CRIT Rate	B (DEF)	Battle Pass. Gives DEF% if 2+ enemies are nearby. Only use if you have C4+ and somehow have enough ER from artifacts.

Constellation Value

Yun Jin is functional at C0, but C6 makes her top tier.

C2: Myriad Mise-En-Scene - (Buff) Normal Attack DMG increased by 15% after using Burst. Simple, effective buff.
C3: Seafaring General - (Scaling) +3 Levels to Burst. Directly increases the % of DEF converted to damage. Very strong.
C6: Decorous Harmony - (God Tier) Characters under the effect of the Burst gain 12% Normal Attack Speed. This is a rare multiplier that significantly increases DPS for Yoimiya and Ayato.

Verdict: C2 is great. C6 is the goal.

Top Team Compositions

1. Yoimiya Vaporize

Main DPS: Yoimiya
Hydro: Yelan / Xingqiu
Buffer: Yun Jin (C6)
Shield: Zhongli

Why it works: Yun Jin buffs Yoimiya's Normal Attacks massively. With C6, the Attack Speed allows Yoimiya to finish her combo strings faster, resulting in more vapes. The Rainbow passive is easily satisfied (Pyro/Hydro/Geo/Geo).

2. Ayato Hypercarry

Main DPS: Ayato
Buffer: Yun Jin
Anemo: Kazuha
Healer/Buff: Bennett

Why it works: Ayato's slashes count as Normal Attack DMG. Yun Jin's Flat DMG buff scales incredibly well with Ayato's high attack speed and Kazuha's DMG% buff/Shred.

Rotations & Combos

Standard Support Rotation:
Supports > Yun Jin EQ > Main DPS

Tip: Always use Yun Jin just before your Main DPS to maximize the buff duration (12s). If using Favonius Lance, weave a Normal Attack after E to ensure a Crit.

Frequently Asked Questions

Yun Jin vs. Bennett?
Bennett is a generalist (ATK buff + Heal). Yun Jin is a specialist (Normal Attack Flat DMG). For Yoimiya, they are often used together. For Ayato, Yun Jin can sometimes be better if Bennett is busy.

Mono Geo or Rainbow?
Rainbow. Her passive explicitly rewards different elements. While she works with Noelle/Itto in Mono Geo, she loses a bit of her passive buff potential compared to running her with Yoimiya/Ayato.
