Xueyi is a Quantum character who follows the Path of Destruction, specializing in Follow-Up Attacks and damage that scales with both ATK and Break Effect. Her unique mechanic centers around Karma stacks, which she gains by hitting enemies or when allies trigger a Weakness Break. Upon reaching 8 stacks, Xueyi automatically unleashes a powerful Follow-Up attack that ignores enemy Toughness, allowing her to remain effective even against enemies without a Quantum Weakness. Her Ultimate also scales with Break Effect and generates additional Karma, while her Talent enables her to quickly regain stacks during combat. This makes her a hybrid unit who excels in both Break-focused teams and traditional DPS roles, particularly in battles where frequent Weakness Breaks and follow-up attacks can be consistently triggered.
Best Cavern Relics
(2) Increases Quantum DMG by 10%.
(4) When the wearer deals DMG to the target enemy, ignores 10% DEF. If the target enemy has Quantum Weakness, the wearer additionally ignores 10% DEF.
The Genius of Brilliant Stars set is the best relic choice for Xueyi, as it enhances her Quantum DMG and allows her to ignore enemy DEF—a valuable stat, since her Follow-Up attacks and Ultimate benefit greatly from it. The set’s 4-piece effect becomes especially effective when enemies are afflicted with Quantum Weakness, making it ideal for maximizing her damage in Break-oriented and Quantum-focused teams.
(2) Increases Break Effect by 16%.
(4) If the wearer's Break Effect is 150% or higher, the Break DMG dealt to the enemy target ignores 10% of their DEF. If the wearer's Break Effect is 250% or higher, the Super Break DMG dealt to the enemy target additionally ignores 15% of their DEF.
A great alternative relic set for Xueyi, especially in Super Break Teams. This set allows her to ignore enemy DEF once her Break Effect reaches a certain threshold, making it highly effective for maximizing her Follow-Up and Break DMG. When properly built, it synergizes well with her kit, which revolves around frequent Toughness breaks and Follow-Up Attacks.
Best Planar Ornaments
(2) Increases the wearer's Break Effect by 16%. When the wearer's SPD reaches 145 or higher, the wearer's Break Effect increases by an extra 20%.
Xueyi’s best Planar Ornament set, as it provides a significant Break Effect boost that directly enhances her overall damage output.
(2) Increases the wearer's ATK by 12%. When the wearer's SPD reaches 120 or higher, the wearer's ATK increases by an extra 12%.
A solid alternative for Xueyi, as it provides a bonus ATK stat that helps boost her damage—provided she reaches the speed threshold, typically 120 SPD.

Another viable alternative for Xueyi is Firmament Frontline: Glamoth, which increases both ATK and overall DMG, making it a strong option for general damage amplification. However, it requires Xueyi to reach at least 135 SPD to activate its minimum DMG boost, which may require some SPD investment depending on your build.

info
Xueyi's main stat priority is Break Effect, as most of her damage scales with it. After that, ATK% and Crit Rate/DMG contribute to boosting her overall output. Speed is also important—especially when using sets like Firmament Frontline: Glamoth or Space Sealing Station, which require meeting specific SPD thresholds to activate their buffs.
Best Light Cones
SourceLight Cone Event Warp

Moth To Flames
When the wearer attacks, increases their ATK by 8~16% in this battle. This effect can stack up to 4 time(s). After the wearer breaks an enemy's Weakness, increases DMG dealt by 12~24%, lasting for 2 turn(s).A strong Light Cone for Xueyi, it offers a stacking ATK boost and an additional DMG bonus when she inflicts Weakness Break—making it especially effective in Break-oriented teams where she can consistently trigger its effects.

SourceStellar Warp, Departure Warp, Character Event Warp, Light Cone Event Warp
Rye Under the Sun
Increases the wearer's ATK by 16~32%. When the wearer defeats an enemy, the wearer's CRIT Rate increases by 12~24% for 3 turn(s).A great Light Cone for Xueyi since it increases her ATK and boosts her CRIT Rate when she defeats an enemy.

Fantastic Adventure
When the wearer uses Basic ATK, Skill, or Ultimate to attack enemies, the wearer gains one stack of Mischievous. Each stack increases the wearer's ATK by 12~24%.Since the ATK buff is gained through three separate conditions, this Light Cone’s effect is less appealing due to the time it takes to fully activate. This makes it a suboptimal choice for fast-paced battles or against enemies that don’t consistently meet all the required conditions.
