Xueyi
Situational—Xueyi Break-scales Quantum Destruction. Ultimate “Divine Castigation” cuts Toughness while ignoring Weakness Type. Best with Fugue / Ruan Mei / Trailblazer • Harmony. Best vs Quantum-weak; Toughness contribution from allies matters. Skip when you have limited Quantum DPS invested.
Xueyi is a 4★ Quantum Destruction Break DPS. Skill “Iniquity Obliteration” is the primary in-combat spend. Ultimate “Divine Castigation” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths
- “Divine Castigation” dumps a huge single-target Quantum multiplier into one elite—boss and Apocalyptic Shadow checks are where this Ultimate earns its trace levels.
- “Iniquity Obliteration” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
- Talent “Karmic Perpetuation” fires Follow-Up ATKs off ally Basics—stack management is the real rotation, not just Skill spam.
- Technique “Summary Execution” opens by hitting the pack on pull-in—use it before every MoC wave, not only in the overworld.
Weaknesses
- “Karmic Perpetuation” Follow-Ups only fire after the Charge/HP conditions are met—wasting Skill or over-healing can strand Xueyi below the Follow-Up threshold for a full cycle.
- Xueyi wants Break Effect supports and Toughness bars that can actually be broken; into awkward weakness line-ups the Complete Combustion / Break loop loses most of its damage.
- As a 4★ Destruction unit, Xueyi is easy to gear for early/mid game but usually loses the niche race to a modern limited option once that banner is built.
- Spamming “Iniquity Obliteration” every turn without watching Skill Points strands the rest of the team—Xueyi is often the SP sink.
Trace Priority
Divine Castigation carries most of the kit’s damage or utility—level this first.
Iniquity Obliteration supports the main rotation—raise after the top priority traces.
Karmic Perpetuation supports the main rotation—raise after the top priority traces.
Mara-Sunder Awl is last priority outside of filling trace materials.
Stat Priority
Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.
Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.
Light Cones
5★ · Path cone
When the wearer attacks, increases their ATK by 0.08% in this battle. This effect can stack up to 4 time(s). After the wearer breaks an enemy's Weakness, increases DMG dealt by 0.12%, lasting for 2 turn(s).
Why it works —Strong Destruction option for Xueyi; use while farming or if signature is unavailable.
5★ · Path cone
Increases the wearer's ATK by 0.24%. When the wearer defeats an enemy or is hit, immediately restores HP equal to 0.08% of the wearer's ATK. At the same time, the wearer's DMG is increased by 0.24% until the end of their next turn. This effect cannot stack and can only trigger 1 time per turn.
Why it works —Flexible alternative on the same path—equip if you already own it at higher superimposition.
4★ · Path cone
Increases DMG dealt by the wearer by 0.2%. The wearer also deals an extra 0.2% of DMG to enemies whose current HP percentage is equal to or higher than the wearer's current HP percentage.
Why it works —Best accessible option for most accounts—raise superimposition when copies drop.
4★ · Path cone
Increases the wearer's ATK by 0.16%. When the wearer defeats an enemy, the wearer's CRIT Rate increases by 0.12% for 3 turn(s).
Why it works —Budget path cone—fine while building the account.
Relics
Team Compositions
Primary Break / Toughness team for Xueyi. Fugue, Ruan Mei, Lingsha are the partners the kit / endgame clears assume first.
Core carry for this shell — owns the damage plan and sets the rotation pace.
Fugue enables Super Break / Toughness pressure rather than a generic CRIT Harmony slot.
Ruan Mei amps Break Effect / action value so Toughness bars die on schedule.
Lingsha keeps Toughness routes alive with heals (and Break-friendly sustain when built that way).
Traces & Eidolons
Traces
Deals 140% of Xueyi's ATK as Quantum DMG to one designated enemy target.
Deals Quantum DMG equal to 175% of Xueyi's ATK to one designated enemy, and Quantum DMG equal to 88% of Xueyi's ATK to any adjacent enemies.
Deals Quantum DMG equal to 300% of Xueyi's ATK to one designated enemy target. This attack ignores Weakness Types and reduces the enemy's Toughness. When the enemy's Weakness is Broken, the Quantum Weakness Break effect is triggered. In this attack, the more Toughness is reduced, the higher the DMG will be dealt, up to a max of 72.0% increase.
When Xueyi reduces enemy Toughness with attacks, "Karma" will be stacked. The more Toughness is reduced, the more stacks of "Karma" are added, up to 8 stacks. When Xueyi's teammates reduce enemy Toughness with attacks, Xueyi gains 1 stack(s) of "Karma." When "Karma" reaches the max number of stacks, consumes all current "Karma" stacks and immediately launches Follow-Up ATK against an enemy target, dealing DMG for 3 times, with each time dealing Quantum DMG equal to 113% of Xueyi's ATK to a single random enemy. This Follow-Up ATK will not add "Karma" stacks.
Immediately attacks the enemy. After entering combat, deals 80% of Xueyi's ATK as Quantum DMG to all enemies.
Eidolons
Increases the DMG dealt by the Talent's Follow-Up ATK by 40%.
Is it worth getting?
Small 4★ bump: Increases the DMG dealt by the Talent's Follow-Up ATK by 40%. Take dupes when they appear on rate-up; never the reason you pull the banner.
Talent's Follow-Up ATK Reduces enemy Toughness regardless of Weakness types. At the same time, restores Xueyi's HP by an amount equal to 5% of her Max HP. When breaking Weakness, triggers the Quantum Break Effect.
Is it worth getting?
Kit add-on: Talent's Follow-Up ATK Reduces enemy Toughness regardless of Weakness types. Evaluate against your supports—pull only if that specific clause solves a problem you actually hit.
Skill Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.
Is it worth getting?
Skill + Basic ATK levels only (+2). Free if you roll into it; never spend currency aiming for E3.
When using Ultimate, increases Break Effect by 40% for 2 turn(s).
Is it worth getting?
Side-grade: When using Ultimate, increases Break Effect by 40% for 2 turn(s). Happy if it drops; not a planned stopping point.
Ultimate Lv. +2, up to a maximum of Lv. 15. Talent Lv. +2, up to a maximum of Lv. 15.
Is it worth getting?
Ultimate + Talent levels only (+2). Skip as a goal—grab it if you overshoot toward E6, never hard-pity for it.
The max stack limit for Karma decreases to 6.
Is it worth getting?
Whale ceiling: The max stack limit for Karma decreases to 6. Only chase if Xueyi is your dedicated Destruction main and E0–E2 already feel finished.
Xueyi is fully usable at E0. Dedicated mains often stop at E2 before chasing higher. First stop: E2. Endgame target: E2.
