Yukong is a 4★ character available in Honkai: Star Rail. Players receive a free copy of her after completing Stage 1 of Memories of Xianzhou. She is an Imaginary buffer belonging to the Harmony Path with some of the strongest team-wide buffs in the game, and she also has excellent single-target Breaking abilities. However, these are contingent upon careful play and are restricted by low buff uptime.



Yukong’s primary mechanic is her “Roaring Bowstrings” stacks which count down based on collective unit turns rather than individual ones. For example, say that you are running a team with Dan Heng • Imbibitor Lunae, Yukong, and two other teammates. If Yukong activates “Roaring Bowstrings” and the other two teammates act before Imbibitor Lunae, he will not get the “Roaring Bowstrings” buff. 

Yukong’s Skill activates her “Roaring Bowstrings” effect. Her Ultimate deals damage to a single target, and activates a potent CRIT Rate% and CRIT DMG% buff that is tied to the duration of “Roaring Bowstrings.” 

This means a certain amount of Speed tuning (aiming for a certain SPD value on Yukong as well as other teammates) is necessary to ensure she functions smoothly. Do note that extra actions  such as Ultimates and follow-up attacks do not consume stacks.

A secondary mechanic is her Talent, which increases her Basic ATK’s potency, as well as doubling its Toughness damage on every other turn, incentivizing alternating Skills and Basic ATKs. 

Her A6 Bonus Ability, Majestas, restores 2 Energy (affected by ERR%) each time an ally takes an action while “Roaring Bowstrings” is active. This counts all manual actions, i.e., Basic ATK, Skill, or Ultimate, but does not count automatic actions like follow-up attacks or revives.

Trace Priority

> > =
Ultimate > Skill > Basic = Talent

The most powerful part of Yukong’s kit is her Ultimate, followed by her Skill. Her Basic ATK and Talent are always used with each other, and therefore have the same priority.


Basic ATK
Basic ATK | Arrowslinger

Arrowslinger [Single Target]

Deals 50%/100%/110% of Yukong’s ATK as Imaginary DMG to a target enemy.

A standard ATK-scaling Basic ATK. It is buffed by Yukong’s Talent.

Skill | Emboldening Salvo

Emboldening Salvo [Support]

Obtains 2 stack(s) of “Roaring Bowstrings” (to a maximum of 2 stacks). When “Roaring Bowstrings” is active, the ATK of all allies increases by 40%/80%/88%, and every time an ally’s turn ends, Yukong loses 1 stack of “Roaring Bowstrings.”
When it’s the turn where Yukong gains “Roaring Bowstrings” by using Skill, “Roaring Bowstrings” will not be removed.

The main highlight of her kit. Activates “Roaring Bowstrings” effect which provides a potent and unconditional ATK% buff.

Ultimate | Diving Kestrel

Diving Kestrel [Single Target]

If “Roaring Bowstrings” is active on Yukong when her Ultimate is used, additionally increases all allies’ CRIT Rate by 21%/28%/29% and CRIT DMG by 39%/65%/70%. At the same time, deals Imaginary DMG equal to 228%/380%/410% of Yukong’s ATK to a single enemy.

A high-cost Ultimate that increases the effects of “Roaring Bowstrings.” Provides a sizable CRIT buff to the team.

Talent | Seven Layers, One Arrow

Seven Layers, One Arrow [Enhance]

Basic ATK additionally deals Imaginary DMG equal to 40%/80%/88% of Yukong’s ATK, and increases the Toughness-Reducing DMG of this attack by 100%. This effect can be triggered again in 1 turn(s).

Yukong’s Basic ATK becomes twice as effective at Breaking when her Talent is activated. A very interesting mechanic that favors rotations where Basic ATKs are usually used every other turn to aid Weakness Breaking.

Technique | Chasing the Wind

Chasing the Wind [Enhance]

After using her Technique, Yukong enters Sprint mode for 20 seconds. In Sprint mode, her Movement SPD increases by 35%, and Yukong gains 2 stack(s) of “Roaring Bowstrings” when she enters battle by attacking enemies.

A unique mechanic that increases Yukong’s Movement SPD when exploring but the extra stacks of “Roaring Bowstrings” are often redundant, and require her to be the one that attacks the enemy.

A2 Bonus
Ascension 2 Bonus Ability | Archerion


Yukong can resist 1 debuff application for 1 time. This effect can be triggered again in 2 turn(s).

Useful defensive Trace that prevents desync due to Control Effects. Its unconditional activation makes it very powerful and a priority.

A4 Bonus
Ascension 4 Bonus Ability | Bowmaster


When Yukong is on the field, Imaginary DMG dealt by all allies increases by 12%.

Increases Imaginary DMG of all allies. A priority for teams with Imaginary damage dealers such as Welt and Dan Heng • Imbibitor Lunae. Otherwise irrelevant.

A6 Bonus
Ascension 6 Bonus Ability | Majestas


When “Roaring Bowstrings” is active, Yukong regenerates 2 additional Energy every time an ally takes action.

Yukong will regenerate Energy when allies take action while “Roaring Bowstrings” is active. Actions include intentional actions such as standard turns, Ultimates, Seele’s “Resurgence,” and Qingque’s Skill. As in most scenarios, Ultimates are queued one after another, right before the main source of damage, which is advantageous for Yukong’s Energy requirements. 

Note that this also activates on the turn you use her Skill.

Note: Trace levels shown are 1/10/12 (Basic ATK 1/6/7).


Eidolon 1
Eidolon 1 | Aerial Marshal

At the start of battle, increases the SPD of all allies by 10% for 2 turn(s).

Often not the most impactful, although SPD increases are almost always beneficial.

Eidolon 2
Eidolon 2 | Skyward Command

When any ally’s current energy is equal to its energy limit, Yukong regenerates an additional 5 energy. This effect can only be triggered once for each ally. The trigger count is reset after Yukong casts her Ultimate.

Enables greater Ultimate uptime, and can even allow for ATK% Rope usage.

Yukong’s Energy regeneration will only trigger when allies reach maximum Energy after she uses her Ultimate, and will not apply retroactively.

Eidolon 3
Eidolon 3 | Torrential Fusillade

Skill Lv. +2, up to a maximum of Lv. 15.
Basic ATK Lv. +1, up to a maximum of Lv. 10.

Increasing the team-wide ATK buff of Yukong’s Skill is always welcome. The Basic ATK damage increase is nice as well.

Eidolon 4
Eidolon 4 | Zephyrean Echoes

When “Roaring Bowstrings” is active, Yukong deals 30% more DMG to enemies.

Since you want to use your Ultimate only when “Roaring Bowstrings” is active, it is a free damage increase to Yukong’s Ultimate.

Eidolon 5
Eidolon 5 | August Deadshot

Ultimate Lv. +2, up to a maximum of Lv. 15.
Talent Lv. +2, up to a maximum of Lv. 15.

Excellent Eidolon since it grants even more CRIT Rate and CRIT DMG to the team.

Eidolon 6
Eidolon 6 | Bowstring Thunderclap

When Yukong uses her Ultimate, she immediately gains 1 stack(s) of “Roaring Bowstrings.”

Extends “Roaring Bowstrings” by another turn, and allows her buff to be utilized on demand for actions that may not have been buffed otherwise. If “Roaring Bowstrings” is not already active, the effect will last until the following turn. Her most helpful Eidolon.


Slow Yukong

A “Slow” Yukong is built to be just slower than your team’s sustain character, similar to how Bronya is often built. Depending on other characters, this can result in Yukong being the slowest character on the team, or the second-slowest. 

For a slower damage dealer, this playstyle allows you to activate “Roaring Bowstrings” right before their turn, allowing for consistent buff uptime. For a faster damage dealer, a Slow Yukong is unable to buff their first turn, but will have more consistent buffs from the second turn onwards, as she will act before them in the turn order. The buffless first turn can also be mitigated using Yukong’s Technique. 

Although this playstyle is referred to as “Slow” Yukong, Yukong herself may be built with high SPD such as 140 or 150, which should still be just lower than her teammates’ SPD.

Fast Yukong

A “Fast” Yukong is built to be faster than your team’s damage dealer. The main goal of running a Fast Yukong is to get as many chances as possible to buff your units by way of Yukong having more turns. 

Significantly more viable with E6’s increase in buff duration.

General Gameplay Notes

While playing Yukong, the following priorities should be kept in mind: 

  1. Don’t die. 
  2. Apply her buffs to damage dealer(s) during their largest windows of damage. 
  3. Manage Energy so she can get her Ultimate back in a timely manner.
  4. Maintain reasonable Toughness damage.

Based upon those overall goals, the following list describes in which scenarios Yukong should use certain actions. 

  1. Use Ultimate or Basic ATK to contribute to Weakness Break if it will prevent imminent death of your party. 
  2. Use Ultimate if “Roaring Bowstrings” is active and the damage dealer(s) will act before its duration is over.
  3. Use Basic ATK if SP and/or Toughness damage is needed. Alternating Basic ATK and Skill is ideal due to Yukong’s Talent only activating every other turn. 
  4. Use Skill if “Roaring Bowstrings” is not active and damage dealer(s) act within the next two turns, or if Yukong has not used a Skill in two turns.

Don’t be afraid to hold Yukong’s Ultimate for a turn or two if “Roaring Bowstrings” and/or damage dealer uptimes are not lining up. 


Yukong has rather high-scaling values for her Talent-affected Basic ATK and her Ultimate, allowing for her to be built for damage. However, in order for a damage build to be possible for Yukong, she must be able to survive. Defensive substats are therefore essential.

Although Yukong does have some defensive parts of her kit, such as her A2 Bonus Ability, she is overall very fragile. Her Base HP and DEF values are also some of the lowest in the game. The tank build aims to reduce the chance of Yukong being knocked down and taking her buffs with her.


Relic Sets

2-Pc Combinations
Using cast-offs from farming for other characters is a great way to cobble together a functional set for Yukong. As the name of the game for tank-built supports is functional, this makes 2-Pc “Tank” sets an excellent choice for Yukong. 

Possible 2-Pc sets include Messenger Traversing Hackerspace, Guard of Wuthering Snow, Longevous Disciple, and Knight of Purity Palace. To a lesser extent (as they do not improve survival), Musketeer of WIld Wheat and Wastelander of Banditry Desert can work as well. 

4-Pc Guard of Wuthering Snow
Players farming for the Genius of Brilliant Stars set likely have enough Guard pieces for a 4-Pc, making it a viable option to chip heal and gain an unreliable bonus Energy increase. This Energy should not be relied on in any way; if you see the Set Effect activate, you likely have larger problems to worry about than Energy.

Planar Ornaments

Fleet of the AgelessIncreases HP and boosts ally ATK%. What’s not to like? Even when running Slow Yukong, she will likely still have enough SPD to activate the Set Effect.
Broken KeelUse it if you have enough substat rolls to activate the CRIT DMG% Set Effect, as it is more effective than Fleet of the Ageless for most CRIT-scalers.

Sprightly Vonwacq
The Energy Regeneration Rate is situationally useful to allow usage of ATK% Ropes. However, this is only the case when using But the Battle Isn’t Over or ERR% Ropes that are not maximum level. 

Keep in mind that Vonwacq wearers begin the battle with a 40% Action Advance. For teams that require precise Speed tuning, this set should be avoided.

Light Cones

Memories of the Past
Yukong’s best option for Ultimate uptime at S2+. One of the only ways to enable a 3-turn Ultimate with an E0 Yukong. Check the table below for more details. 

Meshing Cogs
The other way to enable a 3-turn Ultimate with an E0 Yukong. Gives the equivalent amount of Energy that Memories of the Past does at equal superimposition, but also provides Energy upon Yukong being hit.

Carve the Moon, Weave the Clouds
This Light Cone from the Battle Pass is a great general option for teams that do not require the extra energy from Memories of the Past or Meshing Cogs.

But The Battle Isn’t Over
The Energy Regeneration Rate is situationally useful, and just like Past and Future, this Light Cone requires Speed tuning to ensure the primary damage dealer acts immediately after Yukong.

As Yukong’s Ultimate does not target allies, she is unable to trigger the Skill Point restoration portion of this Light Cone’s Ability.

Past and Future
This Light Cone only works if you can Speed tune to ensure the damage dealer immediately follows her. Situationally useful.

Planetary Rendezvous
An excellent option for teams with Imaginary damage dealers. A niche but viable option.

Dance! Dance! Dance!
A niche option for teams that do not care about desyncs, like Jing Yuan or Clara teams. More turns are always useful for Energy and damage.





CRIT or HP% or DEF%SPDImaginary DMG% or ATK% or HP% or DEF%ERR% or ATK%


Substat Priority:
SPD > Effect RES% = HP% = DEF% > CRIT% > ATK%

How much is enough survivability?
The answer varies with content, teammates, and other factors. The only true metric is that your Yukong is able to survive.
ERR% vs. ATK% Rope

The following table shows Energy requirements and rotation options for Yukong. Memories of the Past can be substituted with an equal superimposition Meshing Cogs.

Keep in mind your team’s SP economy and the content you are playing against when choosing how to play Yukong.

Energy Requirements

Light Cone +15 ERR Rope 2-Pc Vonwacq Rotation (Actions per Ultimate) Notes
Any Yes No 2 Skill 2 Basic
Yes No 3 Skill
Yes No 2 Skill 1 Basic Requires two E2 procs
S1 Memories/Cogs No No 2 Skill 2 Basic
S2 Memories/Cogs Yes No 2 Skill 1 Basic
S5 Memories/Cogs Yes No 1 Skill 2 Basic Requires one ally to use Ultimate while buffed by “Roaring Bowstrings” OR one E2 proc
S1 But the Battle Isn’t Over No Yes 3 Skill Requires one ally to use Ultimate while buffed by “Roaring Bowstrings” OR one E2 proc

A6 is assumed to proc three times per Skill and once per Yukong Ultimate.
When an ERR% Rope is not suggested, other Ropes such as ATK% can be used instead.

Character Comparisons

Yukong vs. Other Harmonies

Yukong’s raw buff numbers are very high. At Trace Level 10, her Skill provides 80% ATK, and her Ultimate provides both 28% CRIT Rate% and 65% CRIT DMG% for the whole party, a whopping 121% Crit Value. Let’s compare that to other characters in a similar buffing niche:

T10, E0 ATK% CRIT Rate% CRIT DMG% DMG% Break Values
Yukong 80% 28% 65% +12% Imaginary DMG Basic: 60U
Ultimate: 90U
Bronya 55% ~10.4%* + 20% 66% Basic: 30U
Tingyun <=50%** 50% (+50 Energy) Basic: 30U
Asta 14%-70% +18% Fire DMG Skill: 60U
E1 Skill: 75U
*Assumed CRIT DMG Body (64.8%) as the only CRIT DMG source on Bronya
**Tingyun’s ATK buff will vary based on build, but will likely be less than 50%.

Looking at the above table, Yukong competes with Bronya for the highest buff modifiers in the category. In addition, she provides a significant amount of Toughness damage as well as a fair amount of personal damage at higher investment.

However, her Ultimate is more expensive than any other Harmony unit, and her SP usage is greedier than most.

Notable Synergies

Damage Dealers

Yukong can be run with most damage dealers, but synergizes best with units with short damage windows and Imaginary damage dealers who can take advantage of her A4.

Welt makes great use of Yukong’s ATK% and CRIT buffs, A4 Bonus Ability, and potential to hold Planetary Rendezvous. He also generally appreciates the additional Imaginary break she provides. Additionally, due to Welt’s strong Crowd Control and the lack of any SPD buffs in his kit, he is one of the most predictable targets for Yukong’s buffs.
Dan Heng Sticker - Second Closed BetaArlan Sticker - Even Immortality EndsYanqing Sticker 01 - Final Closed Beta
Ult-Based Damage Dealers (Civilian Dan Heng, Arlan, Yanqing)
Characters with the majority of their damage focused on their Ultimate can easily be played with Yukong by queuing her Ultimate while “Roaring Bowstrings” is active and then the damage dealer’s Ultimate. 

Being able to control when to insert both Ultimates means that Speed tuning becomes less of an issue.

Dan Heng • Imbibitor Lunae Sticker 01 - Celestial Eyes Above Mortal Ruins
Dan Heng • Imbibitor Lunae
Dan Heng • Imbibitor Lunae enjoys Yukong’s ATK and CRIT buffs, and is one of the few units that can take advantage of her A4. 

Each instance of his Skill enhancement also activates Yukong’s A6, resulting in a minor Energy increase for Yukong’s expensive Ultimate. 

However, Yukong does use a lot of SP to maintain uptime for her buffs, which may result in more difficult SP management if the fight takes more than two cycles. This makes this pairing very efficient in burst scenarios where the content can be cleared quickly.

If run with Imbibitor Lunae, Yukong is likely to be run SP-neutral with one Skill for every Basic ATK.

Sushang Sticker - Even Immortality Ends
Sushang has the same advantage of Ult-based characters in that her damage is condensed into a small window and can be fully affected by Yukong’s buff. 

She can use her Ultimate to advance herself immediately after Yukong’s buffs, or to resync herself SPD-wise. She also can be SP-neutral in some scenarios with E1+, allowing for more frequent use of Yukong’s Skill. 

However, due to Sushang’s damage being spread out during two turns, this requires Yukong to always act directly before her Skill-Ultimate-Skill combo to buff the whole sequence.

Seele’s “Resurgence” can be abused to make sure that up to four of Seele’s actions will all benefit from Yukong’s buffs, but she does have some major downsides. 

She can easily desync from Yukong due to variable SPD and extra turns, resulting in less consistent gameplay and more difficulty Speed tuning. Unlike Sushang, Seele does not have a way to manually realign her Speed, so a desync is rather difficult to fix. 

Seele also is very greedy with SP in some situations, which could result in issues with not having enough SP for either one. This can however be mitigated using careful SP management.

Notable Anti-Synergies

Kafka Sticker 04 - Even Immortality EndsSampo Sticker - Second Closed BetaLuka Sticker 03 - Even Immortality Ends
Damage Over Time (DoT) Units
(Kafka, Sampo, Luka)
Weakness Breaking with Imaginary will delay enemies, resulting in less DoT damage. Also, no DoT units currently CRIT-scale, making Yukong’s CRIT buffs completely worthless.
Blade Sticker 05 - Even Immortality Ends
As an HP-scaler, Blade only benefits from the CRIT buff that has uptime every three turns. You might as well put him on a different team.

Due to how Bronya interferes with turn orders, she can easily interfere with Yukong’s buff time. 

Technically, Bronya can realign desyncs between Yukong, damage dealers, or anyone else by Advancing units to the right places or using her Basic ATKs.

However, this can spiral out of control in terms of SP, Speed tuning, and turn order. Due to this, playing Yukong and Bronya together will likely result in large amounts of emotional pain and frustration.


The main limitation of Yukong is that her buff window is very short and must be timed well.

Standard Hypercarry

Yukong — Damage Dealer — Flex Support — Sustain

Yukong does very well as a support for a standard ATK- and CRIT-scaling hypercarry. All damage dealers mentioned above work in the damage dealer slot, and any SP-positive unit should work for the flex support.

Example Teams

Dan Heng — Yukong — Asta — Defensive Flex

Yukong can be Speed tuned to align her Ultimate’s buff with Dan Heng’s Ultimate. Favors a “Slow” Yukong build as well as all characters having very similar Speed to prevent misalignment of Dan Heng’s Talent being activated as well as Yukong’s Ultimate. SP is somewhat tight due to both Harmony units benefiting from using their Skill, so an SP-positive Asta (two Basic ATKs and one Skill per Ultimate) and an SP-neutral Yukong (alternating Skill and Basic ATK) is suggested.

Yanqing Hypercarry
Yanqing — Yukong — Pela — Gepard

Speed requirements should be flexible for this team, as Yanqing’s Soulsteel Sync lasts until the next turn, allowing his Ultimate (the majority of his damage) to be used at any point in time. Due to Pela and Gepard being highly SP-positive, it’s quite possible that Yukong may be able to get away with only using her Skill. 

Welt Hypercarry
Welt — Yukong — Silver Wolf — Defensive Flex

A team that can be Speed tuned to be either a “Slow” Yukong team or a “Fast” Yukong team. Silver Wolf brings the possibility of Imaginary-Type Weakness application, DEF Shred, and some secondary damage to the team. Welt benefits from all aspects of Yukong’s kit, and is able to take advantage of Yukong’s A4.

Imbibitor Lunae Hypercarry
Imbibitor Lunae — Yukong — Pela — Luocha

A fairly standard Imbibitor Lunae team with Yukong. Can either use a “Slow” or “Fast” Yukong, although Slow is suggested for SP consumption. Yukong should ideally be run SP-neutral (Skill and Basic ATK on alternating turns) unless your Pela and Luocha are speedy enough that you have an immense SP surplus. 

Clara Hypercarry
Yukong — Tingyun — Natasha — Clara

In this case, Yukong should ideally be Speed tuned to match the enemies’ SPD, as most of Clara’s damage happens during that time period. Both “Slow” and “Fast” builds work as long as they match enemy SPD. Both Tingyun A2 and E1’s SPD increase should not be an issue, as Clara and Tingyun’s Speeds do not matter as much as Yukong herself.

Light Cones such as Dance! Dance! Dance! can be used in this scenario, as Yukong Advancing her teammates to desync with herself is not a problem. 

Dual Damage Dealer Comp

Yukong — Damage Dealer — Damage Dealer — Sustain

Multiple damage dealers allow for more flexible Yukong Speed tuning requirements, as her buffs are more likely to run on a damage dealing unit’s turn. 

Example Teams

 Dan Heng — Serval — Yukong — Defensive Flex

As Dan Heng’s Ultimate can be queued right after Yukong’s, it’s very easy to control when his Ultimate is buffed. Serval’s damage is more spread out through her turns, allowing for a higher chance of her damage being buffed by Yukong.

Sushang and Clara
 Sushang — Yukong — Defensive Flex — Clara

In this team, Yukong should be Speed Tuned to go directly before Sushang, and if her buff happens to align with Clara’s damage window, then so be it. Sushang’s SP neutrality with E1+ can be very useful in running more aggressive buff uptime on Yukong. Keep in mind that Sushang and Clara do conflict in terms of game plan (Sushang wants to Break enemies, while Clara wants enemies to attack).
