Honkai: Star Rail – Xueyi build and ascension guide

Become an undying arbitrator of life and death with the best Honkai: Star Rail Xueyi build and deliver judgment without limitation. A 4-Star character following The Destruction and dealing Quantum DMG, Xueyi is a judge of the Ten-Lords Commission on the Xianzhou Luofu who has been granted an artificial body to continue serving her cause even in death. Pretty metal.

Xueyi’s Skill, Iniquity Obliteration, deals Quantum DMG based on her ATK to a single target as well as a reduced amount of damage to adjacent targets.

Her Ultimate, Divine Castigation, causes Quantum DMG based on her ATK to a single foe, ignoring the enemy’s Weakness Type when depleting their Toughness. Should the move cause Weakness Break, Quantum Weakness Break is inflicted. The more Toughness this attack is depleting, the higher its damage is going to be.

Xueyi’s Talent, Karmic Perpetuation, stacks Karma whenever one of her attacks depletes an enemy’s Toughness -– the more Toughness she destroys, the higher the Karma gain is. She additionally gains Karma whenever allies deplete the Toughness of enemies. Once a maximum amount of eight stacks is reached, Xueyi consumes all Karma to unleash a Follow-Up Attack, which deals Quantum DMG based on her ATK three times against random targets.

You can further enhance Xueyi’s power by pulling additional copies of her to boost her Eidolon Level. Eidolon 1 increases the damage of her talent’s Follow-Up Attack by 40%, Eidolon 2 allows that Follow-Up Attack to ignore Weakness Types when depleting Toughness. In addition, they’ll heal Xueyi for 5% of her Max HP. Eidolon 4 increases her Break Effect by 40% for two turns when using her Ultimate and Eidolon 6 decreases the maximum possible stacks of Karma to six, allowing Xueyi to use her Follow-Up Attack earlier.

Honkai: Star Rail – Xueyi: best teams

Xueyi is a very solid single-target damage dealer and will be quite useful against a variety of enemies thanks to her special power of ignoring Weakness Types with some attacks — she could be great at getting rid of Yanqing’s floating swords, for example.

• Xueyi (Main DPS), Trailblazer (Harmony) (Support), Ruan Mei (Support), Lingsha (Support)

Xueyi benefits a lot from the presence of Ruan Mei, since she can buff Weakness Break, and from that of Trailblazer (Harmony), as they can enable Xueyi to deal Super Break DMG. The team is rounded out by Lingsha or Gallagher, who keep everyone healthy and add their own substantial Break DMG capabilities to the party’s offensive output.
