Destruction
Quantum4★Released: 19/03/2025 · v3.1 “You are talking to a puppet. The Commission gifted me this body. The real me has already been reduced to ashes.”
Xueyi is a Quantum DPS who scales off Break Effect: the more Break Effect she has, the harder every one of her attacks hits. She gains Karma stacks whenever the team reduces enemy Toughness, and once she hits the max she launches a Follow-up ATK on her own. She is a free character, and she is a solid pick for clearing the story or getting used to how Break teams play.
A good fit if you don't have a Quantum DPS yet, or if you want to try a Break team with Trailblazer (Harmony), Fugue or Ruan Mei. If you need someone to carry hard content long term, think twice, because she is not a top pick in the endgame modes.
Xueyi wants both Break Effect and CRIT stats. Her Trace turns Break Effect into a DMG boost, but she still needs CRIT, so don't pour everything into one stat.

The Link Rope is always Break Effect. Go for SPD Feet first, though if Sparkle is on the team, Xueyi can run slow with ATK% Feet. On the Planar Sphere, ATK% and Quantum DMG Boost both work: Clairvoyant Loom already gives her a lot of DMG boost of the same kind, so Quantum DMG Boost is worth less on her than on other characters, which makes an ATK% Sphere a very sensible choice.
SPD and Break Effect are the two most important substats. For CRIT, keep a ratio of about 1% CRIT Rate to 2% CRIT DMG. ATK% is nice to have, but don't chase it.
Her Talent is where most of her off-turn damage comes from, so it belongs at the top. Leveling her Skill and Ultimate simply raises their damage. Basic ATK goes last because most of her damage comes from the rest of her kit.
Clairvoyant Loom is her most important Trace: it increases her DMG by an amount equal to 100% of her Break Effect, up to 240%. Perspicacious Mainframe keeps a tally of the Karma stacks that go over the limit, so she launches her Follow-up ATK more often. Intrepid Rollerbearings only adds 10% Ultimate DMG when the enemy still has 50% or more of their Toughness, so unlock it last.
Xueyi already works at E0. E1 raises her Follow-up ATK DMG by 40%. E2 lets her Follow-up ATK reduce Toughness regardless of Weakness Type and restores 5% of her Max HP. E4 adds 40% Break Effect for 2 turns after she uses her Ultimate. E6 lowers the Karma she needs to 6, so she launches Follow-up ATKs more often.
Xueyi is the main damage dealer. Trailblazer (Harmony) and Asta give her a range of buffs, such as Break Effect, ATK and SPD. Natasha keeps the whole team healed.
Fugue and Ruan Mei both raise Xueyi's Break Effect and deal a lot of damage to enemies whose Weakness is broken. Trailblazer (Harmony) or Sparkle can take one support slot. Gallagher is a great replacement healer because his healing scales with Break Effect. In this team, Xueyi can wear Iron Cavalry Against the Scourge for extra Super Break DMG.
Here Xueyi deals damage outside her turn with her Follow-up ATK. The other damage dealer only has to break enemy Toughness to help her build Karma. Jade also raises Xueyi's SPD and works well with her Follow-up ATK.
Silver Wolf uses her Skill to implant a Quantum Weakness on enemies that don't have one. If the enemies are already weak to Quantum, swap her for a Harmony character of another Type, or bring Seele to handle Elite enemies. Fu Xuan raises Xueyi's HP and takes some of the damage for her, while Lynx is the cheaper pick, also Quantum and able to heal the team.
Raises Xueyi's Break Effect and lets her break Toughness far more consistently. A teammate well worth having if you like Xueyi.
The most well-rounded buffer for Xueyi, fitting both CRIT teams and Break teams. Her Break Effect turns into a DMG boost for Xueyi and also speeds up Toughness damage for more Follow-up ATKs, and she adds RES PEN on top.
Lets Xueyi build CRIT stats while still having enough Break Effect for her Trace. Xueyi's Ultimate reduces a huge amount of Toughness, which pairs well with the Super Break DMG that Trailblazer (Harmony) enables.
Her CRIT DMG buff carries over between turns, so Xueyi's Follow-up ATKs hit very hard. With Sparkle on the team, Xueyi can also run slow with ATK% Feet.
Implants a Quantum Weakness on enemies and makes Xueyi's Quantum Break hit harder.
Helps Xueyi act more often, so she gets more Energy for her Ultimate and more Karma stacks.
Helps Xueyi act more often, so she uses her Ultimate and builds Karma faster.
Has a SPD buff and attacks every turn, which gives Xueyi more Karma stacks.
Also brings a SPD buff and always attacks on her turns, adding more Karma for Xueyi.
Makes Xueyi's Quantum Break deal more damage.
Her Talent, Karmic Perpetuation, gives Xueyi stacks of Karma whenever she reduces enemy Toughness, 1 stack for every 30 Toughness reduced. When her teammates reduce Toughness, she gains 1 stack too. At 8 stacks, Xueyi launches a Follow-up ATK that hits random enemies 3 times. The Follow-up ATK itself does not add Karma, but her Trace Perspicacious Mainframe keeps a tally of up to 6 stacks that go over the limit and gives them back afterward, so those extra stacks don't go to waste.
Her Ultimate, Divine Castigation, hits one target and reduces its Toughness whether or not it is weak to Quantum, and if that breaks the enemy, it triggers the Quantum Weakness Break effect. The more Toughness it reduces, the more damage it deals. It deals 120 Toughness damage, which adds 4 Karma stacks right away. So use her Ultimate on enemies that are not weak to Quantum to get the most out of it. Her Skill, Iniquity Obliteration, hits one target and also damages the enemies next to it.
Her Trace Clairvoyant Loom increases her DMG by an amount equal to 100% of her Break Effect, up to 240%. Her Minor Traces already give her 37.3% Break Effect, so a Break Effect Link Rope puts her just over 100%, which means a permanent DMG boost of over 100% on everything. She still needs CRIT stats, though, and stacking only Break Effect will not give you the best results.
Her Technique, Summary Execution, lets Xueyi attack an enemy in the overworld, then deal Quantum DMG to all enemies once the battle starts.
