Xueyi Build
Xueyi is a 4★ Quantum character on the Path of Destruction in Honkai: Star Rail. Below are the character's stats, skills and Eidolons — plus a pity calculator if you plan to pull.
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.
Sub-stat priority: Break Effect > SPD > ATK% > CRIT Rate/DMG
▾
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% 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.
▾
Attacks an enemy, and after entering combat, reduces their Toughness of the corresponding Type.
▾
Immediately attacks the enemy. After entering combat, deals 80% of Xueyi's ATK as Quantum DMG to all enemies.
Increases DMG dealt by this unit by an amount equal to 100% of Break Effect, up to a maximum DMG increase of 240%.
If the enemy target's Toughness is equal to or higher than 50% of their Max Toughness, deals 10% more DMG when using Ultimate.
Xueyi will keep a tally of the number of Karma stacks that exceed the max stack limit, up to 6 stacks in the tally. After Xueyi's Talent is triggered, she will gain a corresponding number of tallied Karma stacks.

3★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.
