Yun Jin is a 4-star Geo Polearm character in Genshin Impact who serves as a dedicated Normal Attack buffer. As the director of Liyue’s Yun-Han Opera Troupe, her support kit revolves around her Elemental Burst, Cliffbreaker’s Banner, which grants all nearby party members bonus flat damage on their Normal Attacks based on her DEF stat. She is one of the most accessible support characters to build, requiring minimal investment to meaningfully boost on-field carries who rely on Normal Attacks. This guide covers her best weapons, artifact sets, talent priorities, team compositions, ascension materials, and constellation benefits.

Understanding Yun Jin’s Kit

Yun Jin’s value as a support comes entirely from her Elemental Burst, Cliffbreaker’s Banner. When activated, it deals AoE Geo damage and grants nearby party members a buff called Flying Cloud Flag Formation. While active, any Normal Attack that hits an opponent deals bonus flat damage scaled off Yun Jin’s current DEF. The buff lasts 12 seconds and can trigger up to 30 times across all party members. When a Normal Attack hits multiple enemies, one stack is consumed per enemy hit, so the quota depletes faster in AoE scenarios.

Her Elemental Skill, Opening Flourish, has tap and hold variants. Tapping produces a quick Geo strike that generates 2 Geo Particles. Holding charges the skill up to two levels while creating a temporary shield based on Max HP, but the Charge Level 2 version takes about 2.5 seconds, which is impractical in most rotations. The tap version is preferred to minimize field time.

Her first Ascension Passive, True to Oneself, allows her to instantly release a Charge Level 2 Skill if she casts Opening Flourish at the exact moment an enemy attack connects, acting as a parry. Her fourth Ascension Passive, Breaking Conventions, increases the Burst’s Normal Attack damage bonus by an additional percentage of her DEF based on how many different elemental types are in the party, ranging from 2.5% with one element to 11.5% with four.

Talent Priority

Leveling Cliffbreaker’s Banner (Elemental Burst) should always be the first priority because the flat damage bonus it provides scales directly with talent level. Getting this talent to Level 8 or above is the initial goal. Opening Flourish (Elemental Skill) can be leveled next for modest improvements, but it is a lower priority since the skill mainly serves as an energy generation tool. Her Normal Attack talent does not need leveling in a support build.

Best Weapons for Yun Jin

Favonius Lance is widely regarded as the best overall weapon for Yun Jin. It provides Energy Recharge as its substat and generates extra energy particles on critical hits, solving her energy needs while also funneling particles to teammates. If using this weapon, aim for at least 50% Crit Rate through artifacts so the passive triggers reliably.

Engulfing Lightning is her best 5-star option purely for its high Energy Recharge substat. Footprint of the Rainbow, a Natlan craftable polearm, offers a substantial DEF increase through its passive and is a strong choice when Yun Jin already meets her Energy Recharge requirements through artifacts or a Geo battery. Prototype Starglitter is a solid free-to-play craftable alternative with a high Energy Recharge substat. Kitain Cross Spear can reduce energy requirements over time through its passive, though the Elemental Mastery substat is wasted on her, and the passive drains 3 energy when the Skill is cast, so Burst should always be used before Skill.

Best Artifact Sets for Yun Jin

The primary artifact set for Yun Jin is the 4-piece Husk of Opulent Dreams. The 2-piece bonus grants DEF%, and the 4-piece effect stacks additional DEF% and Geo DMG Bonus while the character is off-field. Since Yun Jin spends almost all her time off-field after casting her Burst, the set accumulates stacks passively, providing a substantial DEF boost that directly improves her Normal Attack buff. If you lack a complete 4-piece set, a 2-piece Husk combined with any other 2-piece DEF% or Energy Recharge set works as a temporary alternative.

For main stats, the recommended setup is DEF% on the Sands (or Energy Recharge if ER requirements are not met through substats), DEF% on the Goblet, and DEF% on the Circlet (or Crit Rate if using Favonius Lance). For substats, prioritize Energy Recharge first, followed by DEF% and flat DEF.

Energy Recharge Requirements

Yun Jin needs her Burst available every rotation. When she is the only Geo character on the team, she requires approximately 220% to 250% Energy Recharge. When paired with another Geo character who generates Geo Particles, such as Zhongli or Albedo, the requirement drops to around 150% to 200%. Meeting these thresholds is essential. A Yun Jin who cannot use her Burst consistently provides no value, so it is always better to prioritize Energy Recharge over maximum DEF if you have to choose.

Best Team Compositions

Yun Jin pairs best with characters whose primary damage source is Normal Attacks. Yoimiya is one of her strongest partners, as her entire rotation revolves around rapid Pyro-infused Normal Attacks. A common team includes Yun Jin, Yoimiya, Xingqiu or Yelan for Hydro application and Vaporize, and Zhongli for shielding and Geo Resonance.

Arlecchino also benefits significantly because her combat loop includes Normal Attacks enhanced by her Bond of Life mechanic. A team of Yun Jin, Arlecchino, Zhongli, and Bennett provides both Geo and Pyro Resonance. This pairing becomes especially strong at Yun Jin’s Constellation 2. Ayato is another strong partner, as his Elemental Skill drives rapid Normal Attacks that benefit from the buff. Wanderer also synergizes well because his floating state converts Normal Attacks into powerful Anemo strikes, and at Yun Jin’s Constellation 6, the 12% Normal Attack Speed bonus lets him land more hits during his limited Skill duration.

Ascension Materials

Leveling Yun Jin to 90 is recommended because her base DEF jumps from 620 at Level 80 to 734 at Level 90, directly improving her Burst buff. Her ascension requires Prithiva Topaz gems from Geo bosses, 46 Riftborn Regalia from the Golden Wolflord on Tsurumi Island, 168 Glaze Lilies found in Liyue Harbor and Qingce Village, and Damaged, Stained, and Ominous Masks dropped by Hilichurls and their variants.

For talent materials, she needs Teachings, Guides, and Philosophies of Diligence from Taishan Mansion (available Tuesday, Friday, and Sunday), Ashen Heart from the La Signora weekly boss, and Crown of Insight from events or regional tree offerings for leveling a talent from 9 to 10.

Constellation Overview

Yun Jin works well at Constellation 0, which is part of what makes her a low-investment support. Constellation 2 is her most impactful early unlock, granting all nearby party members a 15% Normal Attack damage increase for 12 seconds after her Burst is used. Constellation 4 boosts her DEF by 20% for 12 seconds when she triggers Crystallize, a reaction that occurs naturally in multi-element teams. Constellation 6 is her strongest overall, granting characters under her Burst buff a 12% increase to Normal Attack Speed, which translates into more hits and higher DPS for carries like Yoimiya and Wanderer.

Yun Jin is a straightforward and effective support who excels at buffing Normal Attack damage for on-field carries. Her low investment requirements, reliance on easily obtainable DEF artifacts, and compatibility with popular DPS characters like Yoimiya, Arlecchino, Ayato, and Wanderer make her a valuable team member. By focusing on Energy Recharge to guarantee Burst uptime and stacking DEF through the Husk of Opulent Dreams set, you can turn Yun Jin into a reliable buffer who meaningfully increases your team’s damage output.
