What Combat Type is Xueyi?

Xueyi is a 4-star Quantum character on the Path of Destruction, from The Xianzhou Luofu, released in version 1.6.

What stat does Xueyi scale on?

Xueyi's abilities multiply ATK. That is read from the scaling rows on the Skill and Ultimate, not from the ability description, so it reflects what the game actually multiplies rather than what the text mentions.

What is the best Light Cone for Xueyi?

I Am As You Behold is the closest fit on the data: it is a 5-star Destruction Light Cone with 635 base ATK at level 80, and its passive acts on ATK. A Trail of Bygone Blood is the best 4-star alternative.

Which relic set should Xueyi use?

Poet of Mourning Collapse. Its 2-piece bonus is: Increases Quantum DMG by 10%. Its 4-piece bonus is: Decreases the wearer's SPD by 8%. Before entering battle, if the wearer's SPD is lower than 110/95, increases the wearer's CRIT Rate by 20%/32%. This effect applies to the wearer's memosprite at the same time.

Which Planar Ornament should Xueyi use?

Firmament Frontline: Glamoth. Its 2-piece bonus is: Increases the wearer's ATK by 12%. When the wearer's SPD is equal to or higher than 135/160, the wearer deals 12%/18% more DMG. Planar Ornaments have no 4-piece bonus; the sphere and the rope are the whole set.

How much does it cost to max Xueyi's traces?

Taking one ability from level 1 to 10 costs 522,000 Credits and 1× Tracks of Destiny among other materials. The Materials tab lists every item per level.

What does Xueyi E1 do?

Dvesha, Inhibited: Increases the DMG dealt by the Talent's Follow-Up ATK by 40%.

Break effect is Xueyi's best damage scaling stat when including Quantum Entanglement in the equation. Stacking only Break Effect will not yield the best results though, so aim for a good CRIT and CRIT DMG ratio and as high Break Effect as possible. Pick up ATK% as a bonus and ensure you have enough Speed through your teammates or sub stats to hit your desired Speed breakpoint.
