Honkai: Star Rail Xueyi Character Guide

Introduction

Xueyi is a DPS character who strongly focuses on depleting Toughness. Her Ultimate can deplete enemy Toughness while ignoring Weakness Type, and she gains Charges whenever an ally reduces an enemy's Toughness. When her Charges are stacked to their maximum capacity, her follow-up attack can be triggered.

Skills Overview

Basic Attack - Mara-Sunder Awl

Deals 50%—110% of Xueyi's ATK as Quantum DMG to a single target enemy.

Skill - Iniquity Obliteration

Deals Quantum DMG equal to 70%—154% of Xueyi's ATK to a single enemy, and Quantum DMG equal to 35%—77% of Xueyi's ATK to any adjacent enemies.

Ultimate - Divine Castigation

Deals Quantum DMG equal to 150%—270% of Xueyi's ATK to a single target enemy. 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 36%—64.8% increase.

Talent - Karmic Perpetuation

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 allies reduce enemy Toughness with attacks, Xueyi gains 1 stacks of Karma.

When Karma reaches the max number of stacks, consumes all current Karma stacks and immediately launches a follow-up attack against an enemy target, dealing DMG for 3 times, with each time dealing Quantum DMG equal to 45%—99% of Xueyi's ATK to a single random enemy. This follow-up attack will not add Karma stacks.

Technique - Summary Execution

Immediately attacks the enemy. After entering combat, deals 80% of Xueyi's ATK as Quantum DMG to all enemies.

Ascension 2 - Clairvoyant Loom

Increases DMG dealt by this unit by an amount equal to 100% of Break Effect, up to a maximum DMG increase of 240%.

Ascension 4 - Intrepid Rollerbearings

If the enemy target's Toughness is equal to or higher than 50% of their Max Toughness, deals 10% more DMG when using Ultimate.

Ascension 6 - Perspicacious Mainframe

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.

TLDR

With Xueyi, everything is about Karma. Every time Xueyi reduces the enemy's Toughness, she'll get Karma, every time an ally reduces the enemy's Toughness, Xueyi gains another Karma. Once she gains enough Karma (8 stacks at E0, 6 stacks at E6), she will activate her Talent to deal a follow-up attack, which is one of her best damage outputs. The only downside is this attack will target random opponents.

Another of her damage output is from her Ultimate. Xueyi will deal damage that ignores Weakness Types and reduces the enemy's Toughness, which indirectly helps her to stack Karma.
