• Xaihi Overview

Xaihi is a Cryo support who specializes in damage amplification, healing, and Cryo stack application. Her kit revolves around her Battle Skill, which creates a crystal with charges that heal allies and trigger elemental damage amplification when they reach full HP, and her Combo, which activates after consuming both charges to deal Cryo damage and apply Cryo stacks.

Xaihi enables her passive by applying Cryo stacks on enemies that are already affected, increasing the Cryo damage they take and strengthening her role as a Cryo-focused amplifier. Her Ultimate provides teamwide Cryo and Nature damage amplification that scales with Intellect, making stat optimization important to reach its cap.

Xaihi performs best in teams that can consistently apply and consume Cryo stacks, allowing her to maximize amplification during burst windows. She is especially effective in Cryo and Cryo + Nature compositions where her buffs, healing, and stack application directly increase overall team damage.

Xaihi Skill Priority

Xaihi Best Weapons and Essence Priority

Xaihi scales primarily with Intellect and Will, as Intellect increases her damage amplification while Will improves her healing consistency, which is required to reliably trigger her buffs. Weapons that provide Intellect, energy regeneration, or team utility effects pair best with her kit, since her value comes from amplifying team damage rather than dealing it herself.

Her best-in-slot option is Detonation Unit, which helps reach Intellect thresholds while increasing elemental damage taken by enemies, directly enhancing her amplification role. Chivalric Virtues is a strong alternative once Intellect requirements are met, providing additional healing and a teamwide attack buff when healing allies. Lower rarity options such as Freedom to Proselytize or Stanza of Memorials can also be used, though they are more situational and offer less overall team damage value.

Recommended Essence

Xaihi Best Gear Set

In the early game, she can use any gear that provides Intellect or Will, as both improve her amplification and healing consistency. In the late game, the Eternal Xiranite set is her best option, as it increases team damage whenever she applies amplification, reinforcing her role as a dedicated support.

Xaihi Best Teams

Xaihi works best in Cryo teams that can consistently apply and consume Cryo stacks to maximize her amplification. She pairs especially well with main DPS operators like Last Rite and Yvonne, who benefit from her Cryo stacks, healing, and strong damage buffs.

Xaihi prefers coordinated burst rotations where teammates apply Cryo stacks before her Combo triggers, allowing her passive to activate and increase Cryo damage taken. During these windows, she can use her Ultimate to provide teamwide Cryo and Nature amplification, enabling high burst damage and making her a core support in both pure Cryo and Cryo + Nature compositions.
