Should you pull Xueyi?

Xueyi is a dirt-cheap Quantum Super Break DPS since she's a 4-star everyone owns. Build her if you enjoy break playstyles and have Fugue/Ruan Mei/Harmony MC; skip if you already run a strong 5-star DPS and dislike break teams.

Pros
  • 4-star, easy to own, E6 farmable from banners
  • Shines in Super Break teams and Apocalyptic Shadow
  • Follow-ups ignore Weakness type and self-heal
  • Cheap investment, no 5-star cone required
Cons
  • Energy-hungry, needs a regen source
  • Mediocre outside dedicated Super Break teams
  • 4-star ceiling below true 5-star DPS
  • Heavily reliant on Fugue/Ruan Mei/HMC to break Weakness

How to play

Each turn: use Basic/Skill to stack Karma; at 8 stacks her follow-up auto-triggers and helps break Weakness.

Fire the Ultimate as soon as you have energy since it ignores RES and has its own Weakness-Break rules. Focus already-broken targets so Super Break hits hardest.

Eidolons

How far to invest, which milestones matter

E0 plays fine. As a 4-star her copies farm from banners, so aim for E6 (fewer Karma stacks needed, faster follow-ups). E1 (+40% follow-up DMG) is the best stopping point before E6.

E1
Dvesha, Inhibited★★★☆☆
Increases the DMG dealt by the Talent's Follow-Up ATK by 40%.
Boosts the Talent's Follow-Up ATK damage by a flat 40%, a solid but single-number buff to her main damage source.
Xueyi's Eidolon×1 Xueyi's Eidolon
E2
Klesha, Breached★★★★★
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.
Lets the Follow-Up ATK reduce Toughness regardless of enemy weakness, heals 5% Max HP, and can trigger Quantum Weakness Break, fundamentally changing how her kit functions.

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

Karma, Severed★★★★☆
When using Ultimate, increases Break Effect by 40% for 2 turn(s).
Using the Ultimate grants +40% Break Effect for 2 turns, a strong buff since her damage scales heavily with Break Effect.

Saṃsāra, Mastered★★★★★
The max stack limit for Karma decreases to 6.
Lowers the Karma stack cap to 6, letting the Follow-Up ATK trigger noticeably faster and boosting her damage cadence, a major E6 power spike.

Skills & Traces

What to level first — tap each skill for details

Skill Leveling Priority

Talent ★★★★★ The Talent stacks Karma and unleashes the Follow-Up ATK that serves as Xueyi's core damage source, so it should be leveled first.
Ultimate ★★★★☆ The Ultimate deals heavy damage, ignores Weakness Types and scales higher the more Toughness it removes, directly supporting her Break-focused kit.
Skill ★★★★☆ The Skill is her main tool to whittle enemy Toughness, build Karma quickly, and splash damage to adjacent foes, so it should be leveled close behind Talent and Ultimate.
Basic ATK ★★☆☆☆ The Basic ATK only deals modest single-target damage and isn't a core damage pillar, so it stays lowest priority as usual.
Trace priority: A2 > A6 > A4 Eidolon priority: E1 > E2 > E4 > E6 > E3 = E5

Xueyi FAQ

What is the best Light Cone for Xueyi?

The best Light Cone for Xueyi is Indelible Promise (top pick). See F2P options in the Light Cones section above.

Is Xueyi worth pulling?

Xueyi is a dirt-cheap Quantum Super Break DPS since she's a 4-star everyone owns. Build her if you enjoy break playstyles and have Fugue/Ruan Mei/Harmony MC; skip if you already run a strong 5-star DPS and dislike break teams.

What is the best team for Xueyi?

Core Super Break: Xueyi + Fugue + Ruan Mei + Lingsha (or Gallagher) — Fugue and Harmony MC turn Break Effect into real damage. F2P swaps Fugue for Harmony Trailblazer. Lingsha/Gallagher heal and add extra breaking.

How much Energy does Xueyi's Ultimate cost?

Xueyi's Ultimate costs 120 Energy. See the Skills section above for the Energy gain and Break DMG of every skill.

What materials does Xueyi need to reach max Ascension?

How to read this build page

Every character build page has these parts: recommended Light Cone/Relic sets and stat table, a Trace/skill leveling order, Eidolon milestones worth considering, and a reference SPD threshold. Read them in that order — gear tells you "what to use", Traces tell you "what to level first", Eidolon tells you "is it worth pulling dupes", SPD tells you "how fast you need to be to keep the rotation on time". The section below explains how to read each part and applies the same way to every character on the site — check the exact numbers in the table above this section, since community sources sometimes differ by a few points.

Why the Light Cone and Relic picks make sense

Most characters have a "signature" Light Cone built for their exact role, plus a few cheaper substitutes from the standard banner or easy-to-get 3-4★ cones. Missing the signature isn't a dead end — most characters keep most of their power with a well-matched substitute, typically losing somewhere between a few percent and roughly a fifth of total damage depending on the setup, per most public comparisons.

  • Relic sets (2pc+2pc or 4pc) are picked for the set effect that fits that character's role (single-target DPS, AoE, shield/healing support, Break damage, and so on).
  • Main stats per slot (Body/Feet/Sphere/Rope) and substats follow a priority that changes by role: DPS roles usually chase CRIT Rate/CRIT DMG before ATK%; Break-focused roles prioritize Break Effect; support/healing roles often value Effect Hit/RES or Outgoing Healing over pure CRIT.

These weights differ per character and can shift slightly between ranking sources — follow the exact priority table above rather than applying one formula to every role.

Trace/skill leveling order by role (a general guideline, not a fixed rule)

There's no single order that's correct for every character, and community sources sometimes disagree depending on the team the character is used in — but the general pattern by role is:

  • DPS: level whichever skill (Skill or Ultimate) carries most of the damage for that character first, with Basic ATK usually last if it isn't the main damage source.
  • Support/Buffer: prioritize Traces that boost buff strength or the skill that applies the effect over Basic ATK, since this role's value comes from lifting the team rather than personal damage.
  • Healer/Shielder: prioritize the main healing or shield skill first, since that is the reason the team runs this character.
  • Break/CC: prioritize whichever skill contributes the most Toughness Damage, since the Break/Weakness Break window is where the team dumps damage.

Major Traces unlock at fixed ascension levels in-game, not by choice — but which one to level first (when resources are limited) should follow the role priority above. Since the exact order can differ between ranking sources, check the specific recommendation in the table above for this character.

Eidolons: how far E0 gets you, and which milestone is worth considering

General rule: most characters at E0 (no duplicates) already handle most content, even 5-star characters. Eidolons are a duplicate-fueled upgrade system — higher levels cost more resources for a smaller power gain, and the actual gain varies a lot per character (some barely change role at E0, others shift how they're played at a specific level). The milestones most often cited by the community tend to sit at E1, E2, or E6 depending on the character — but none of these are required to clear the game's content. Check the Eidolon section in the table above for this character's specific milestone and gain; if sources disagree on how to rate a milestone, trust the in-game effect description over a pre-set percentage number.

How to think about SPD breakpoints

SPD (Speed) controls how often a character acts in the turn order — higher SPD means denser actions, and for some roles (especially support/healing that need to buff or heal before the team gets hit) hitting the right SPD "breakpoint" matters more than the raw SPD number. Values like 101 or 134 SPD are often cited as community-common breakpoints (letting a character act again before or after a specific point in certain team setups) — this is crowd-verified action-gauge math, not an official fixed number the game states for every situation. The right breakpoint also depends on the team and allies' SPD, so treat the SPD suggestion in the table above as a starting point to adjust from, not a mandatory target.
