Welcome to the Yun Jin Guide!

Yun Jin, an operatic icon in the world of Teyvat, is a fairly straight-forward character to understand. But as with many opera shows, there is depth to what she provides for your team.

In this guide, we will explain everything you need to know about this elegant performer!

Why Play Yun Jin?

Yun Jin is a 4-star Geo Polearm user that specializes in increasing your team's Normal Attack (NA) DMG output with her Elemental Burst. Similar to several other Geo characters, she scales heavily off her DEF stat, making her very easy to build and giving her access to strong artifact options such as the Husk of Opulent Dreams set. If you have an on-field DPS that uses NA strings in their rotations, it is worth exploring how Yun Jin may benefit your team.

Is Yun Jin a shielder?

Yun Jin is not a shielder. Though her Elemental Skill creates a temporary shield, it only lasts for the duration of holding her Skill, and its purpose is to allow Yun Jin to counter (parry) incoming attacks without taking damage. Building HP is not recommended and does not benefit her kit in any way.

Does Yun Jin work with Gorou?

As an off-field support, Yun Jin Elemental Burst does not benefit from Gorou’s DEF buff. As it only applies to on-field characters, and Yun Jin’s Elemental Burst being dynamic (checks Yun Jin’s stats every instance) means that she will not benefit from Gorou’s buff unless she is on-field.

Damage Calculation

Infographic by Swiftfyre#0502

The infographic above shows Yun Jin’s Bonus Flat DMG in calculation. It explains that the current on-field character’s ATK stat and Normal Attack talent% does not affect Yun Jin’s Bonus Flat DMG. This means characters with high DMG Bonus% and high Crit multipliers can capitalize on Yun Jin’s Burst effectively.

This also means that characters that have faster/multi-hit Normal attacks benefit more from Yun Jin’s burst than those who do not.

Why Normal Attack Hit Count Matters

To have a complete perspective, let’s compare two hypothetical characters.

You can see that both characters deal a total of 500 damage. Which doesn’t say much at the moment.

Now let’s add Yun Jin into the mix. If you have been reading carefully from earlier then you would remember that her Bonus Flat DMG activates per hit.

As we can see, characters that are able to hit more by either faster attack speed or from AoE benefit more from Yun Jin than those who do not.

Moreover, this illustrates how Yun Jin’s Bonus Flat DMG functions as a flat amount of damage added. As such, the actual damage per hit is irrelevant to the amount of damage Yun Jin adds. For technical details regarding Yun Jin's skills, visit the KQM Theorycrafting Library.

Yun Jin's entire kit works at C0. Her Constellations are more or less optional, but are nonetheless great upgrades to her kit.

For a more detailed analysis on constellation comparisons, see kol#1593’s Yoimiya Yun Jin constellation comparisons.

Normal Attack Support

This type of playstyle is what Yun Jin excels in. Providing significant Bonus Flat DMG to Normal Attacks makes her viable with most characters, especially those whose playstyles revolve around their Normal Attacks.

In this playstyle, Yun Jin will be swapping in to cast her Elemental Skill and Burst, and then swapping out immediately, usually to the on-field DPS. It is usually better to use Skill > Burst in that order, as it allows her to catch the Particles generated from her Skill.

Note: It is generally not worth significantly delaying rotations to land a Charge Level 2 Skill or a perfect parry. Unless a perfect opportunity arises, using a quick Press Skill -> Burst is generally better for team DPS.

Support Talent Priority

On-Field Physical DPS

Yun Jin’s Normal Attacks aren’t all that special: her scalings are relatively weak, and she does not boast any significant attack speed, thus making her generally outclassed as an on-field NA-using DPS.

However, as a Polearm user, Yun Jin has access to Crescent Pike, one of the best Physical DPS weapons in the game. When playing her as an on-field DPS, she makes use of her own Elemental Burst alongside Pike to boost her Normal Attack damage. Having a team that enables Superconduct is recommended.

On-Field DPS Talent Priority

At the time of writing this guide, there is not a Polearm that synergizes particularly well with Yun Jin’s kit. The next best option for Yun Jin is equipping her with an ER Polearm to help meet her ER requirements, which includes the following:

Favonius Lance	Providing 30.6% ER for Yun Jin along with its passive, which generates clear particles for her and her team, Favonius Lance is one of her safer options in many of her teams. Using this Polearm may encourage investment into CRIT Rate for its passive. However, it is still recommended to continue to prioritize DEF% and ER% as investing into CRIT Rate causes Favonius Lance to fall off in teams that do not require extra energy. In general, around 45% CRIT Rate is recommended to consistently activate its Passive if you choose to invest for it.
Engulfing Lightning	Providing 55.1% ER and even more after casting Burst makes this weapon quite powerful on Yun Jin. However, using this weapon on Yun Jin has a huge opportunity cost, since other characters such as Raiden utilize its Passive much better. Furthermore, although it triumphs over other ER stat sticks, it does not do so by very much. Nonetheless, it is still a solid weapon if no other character in your account wants it.
The Catch	Providing 45.9% ER for Yun Jin makes this weapon a good F2P pick. However, similarly to above, using this weapon comes at a huge opportunity cost, as characters like Xiangling or Raiden can make better use of its powerful Passive. (Also comes at the cost of your sanity; good luck fishers.)
Prototype Starglitter	Providing 45.9% ER for Yun Jin makes this weapon another good F2P pick. Exactly the same ER as The Catch, but with less opportunity cost and a generally worse passive, but requires a Polearm billet which may or may not be a problem depending on your account.
Kitain Cross Spear	While Kitain may seem like a good choice by providing Flat Energy for Yun Jin through its Passive, it is simply worse than other options that provide raw ER, such as the other options above. To perform similarly, Kitain requires weapon refinements which are resource-expensive. Furthermore, its Passive complicates rotations by preventing the standard Skill -> Burst combo. While it works as an alternative option, it is generally not recommended.
Skyward Spine	Providing 36.8% ER for Yun Jin makes this weapon usable, but there are better 4 star and 5 star options for her. Not recommended.
Deathmatch	The only Polearm in the game that provides DEF% for Yun Jin. Even at R5, it provides less total useful stats than other options listed above, and also loses all of its value in single target scenarios. Not recommended unless trying to maximize DEF for showcases.

For a more detailed analysis on weapon comparisons, see kol#1593’s Yoimiya Yun Jin weapon comparisons sheet.

ER Requirements

The amount of ER that Yun Jin needs will heavily depend on her team comp and the usage of weapons such as Favonius Lance. Here is a brief summary:

Use the Energy Recharge Calculator by Zakharov#5645 to determine exact requirements for your team and rotation.

Artifact Stats

Main Stats

Sands ― DEF% / ER%	DEF% is recommended so that the Bonus Flat DMG from her Elemental Burst is maximized. ER% is only recommended to reach her requirement in the case that you have below par substat rolls.
Goblet ― DEF%	DEF% is recommended as it furthers your total DEF to increase her Bonus Flat DMG. This option is generally best even when prioritizing her Elemental Skill damage, since both her Skill and Burst benefit from DEF%. Geo DMG Bonus% is only recommended for niche builds that prioritizes her Elemental Skill damage or her initial Burst damage. Otherwise DEF% is strictly better since Yun Jin only deals Geo damage 2-3 times per rotation and you generally get higher team DPS with DEF%.
Circlet ― DEF%	DEF% is recommended to maximize Yun Jin’s Elemental Burst Bonus Flat DMG. If using Favonius Lance, DEF% is also the better option whether or not you already have enough CRIT Rate from Substats to reliably trigger Favonius Lance’s Passive. CRIT Rate% is situationally recommended when you are using Favonius Lance to more reliably activate its Passive.

Substats

Substat Priority
ER% = DEF% = CRIT Rate% > Flat DEF

Artifact Sets

4pc Husk of Opulent Dreams (Husk)	Providing a total set bonus of 54% DEF and 24% Geo DMG. This artifact set is currently her best set for support builds due to its reliability and ease of use. Pre-stacking Husk is simple (wait 6 seconds at the beginning of a chamber while not in the first slot of a team), and maintaining stacks is similarly easy, as Yun Jin usually yields field time to the on-field DPS.
2pc Husk + 2pc Emblem of Severed Fate	Best used for balancing ER% and DEF% Substats on Yun Jin. This is a great option especially if you have great Substats on your Emblem pieces.
4pc Noblesse Oblige	While providing an ATK% bonus for the entire team is beneficial, Yun Jin should not prioritize this set as her first choice since other characters may utilize the set with a lower opportunity cost. However, if no one else in the team can use the artifact set, it is generally equivalent to 4pc Husk for team DPS.
4pc Archaic Petra	Providing a large Elemental DMG Bonus% for your team makes this set have high potential for some teams (higher than Husk in all team comps). Performing Yun Jin’s Skill -> Burst combo allows her to pick up the Crystallized shard semi-consistently: Using Archaic Petra Example However, there are many caveats that should be considered when using 4pc Archaic Petra: Crystallizing the correct Elemental Shard may be challenging in certain rotations, especially in reaction teams. Sometimes Yun Jin may not collect the Shard immediately. Dashing to collect a Shard can be difficult depending on enemy size and other factors, which costs field time and may result in either a DPS loss from the extra time spent or a DPS loss from just not being able to pick up the Shard at all. Once you acknowledge these caveats and can account for them when using Archaic Petra, you will see high returns in team comps that can utilize the buff.

For a more detailed analysis on artifact comparisons, see kol#1593’s Yoimiya Yun Jin artifact comparisons sheet.

Many characters make use of their Normal Attacks for damage as such, Yun Jin can be placed in a wide variety of team comps. Since there is a lot to cover, we will be focusing on some of Yun Jin’s key synergies and team comps.

Yoimiya

Yoimiya relies on her NAs to do the majority of her damage. Therefore, Yun Jin is naturally one of her best supports. In most cases, Yun Jin’s Burst is comparable to or greater than Bennett’s Burst for overall team DPS, at similar Constellations.

Here is a generalized example of a Yoimiya team with Yun Jin as a support:

Because Yun Jin’s Burst does not interfere with reactions, Yoimiya is free to run many team variations, such as pure Pyro, Vaporize, Double Geo, or Overload. Additionally, unlike Bennett, Yun Jin does not restrict gameplay to within a small circle, allowing Yoimiya to fully utilize her mobility.

In many cases, Yun Jin can replace Bennett, freeing him up for the other team in the Spiral Abyss.

Hu Tao

Since Hu Tao's release, her Double Geo team (Xingqiu Zhongli Albedo) has always been one of the most popular end-game team comps, combining her unrivaled Single-Target damage output with strong shields and simple, flexible rotations. However, while incredibly powerful, this team requires three limited 5 stars, making the team inaccessible to many players.

With enough practice using Hu Tao's N2C combo (2 NAs into a CA), Yun Jin serves as a good alternative to Albedo in this team. Compared to a similarly invested Albedo, Yun Jin will perform very slightly worse at C0 and similarly at C3 or higher.

Here is the best Hu Tao team with Yun Jin as a support:

Ayato

Ayato is another character that relies on their NAs to provide a considerable amount of damage. Yun Jin can be slotted in several team compositions and raises Ayato’s personal damage by a considerable amount. However, keep in mind that Yun Jin can be outshined by other characters that provide more team damage and utility.

Here is a generalized Ayato team with Yun Jin as a support:

Unlike most other On-field Normal Attack DPS, Ayato bypasses the caveats of attack sequence reliance, auto-locking hell, and chasing after enemies when using his Elemental Skill. Which means that Yun Jin herself improves in the team in comparison to other DPS variants as she is able to provide more Bonus Flat Damage for the team through continuous attacks.

Noelle

Although Noelle does not have very high attack speed, the large AoE of her swings allows her to easily hit multiple enemies per NA. This allows her to make good use of Yun Jin’s Bonus Flat DMG.

Noelle’s teams are very flexible beyond this two-unit core and can be tailored to content; with GMC, Albedo, Gorou, Fischl and Beidou all being examples of viable options.

Visit the Noelle guide for more information!

Ningguang

Both Ningguang’s N1C and N2C combos allow her to benefit from Yun Jin's Elemental Burst, making Yun Jin a decent fit for her teams. Each of Ningguang’s Normal Attacks hits twice, and each individual hit benefits from Yun Jin’s Burst. The two can also help by batterying each other and activate Geo Resonance, creating decent synergy between them.

However, Ningguang generally does not have extended field time in her teams, making her unable to capitalize on Yun Jin’s Burst very effectively. When possible, she often prefers other Geo teammates such as Albedo or Zhongli over Yun Jin.

Here is a generalized example of a Ningguang team with Yun Jin as a support:

Visit the Ningguang guide for more information!

Zhongli

Because Zhongli’s NA string has many fast multi-hits, he makes very good use of Yun Jin’s Burst. Combined with his extra HP scaling on his A4 talent and additional damage from Crescent Pike, Yun Jin works well with an on-field Physical DPS Zhongli build, often more than doubling his Physical damage output.

Here is a generalized example of a Zhongli team comp with Yun Jin as a support:

Note: Replacing the Cryo character with Beidou is also a viable team and may yield higher DPS in AoE scenarios.
