Xaihi

endgame support

support healer buffer cryo

Xaihi excels as a versatile support who heals the entire party and amplifies Arts-centric teams, especially Cryo and Nature compositions. Her Battle Skill and Ultimate provide consistent buffs and healing, while her Combo Skill applies Cryo Infliction for extra team synergy. She is rated S-tier because of her strong team-wide buffs, reliable sustain, and the ability to boost both damage output and survival in high-end content.

This endgame build maximizes Xaihi’s role as a defensive buffer. Chivalric Virtues enhances her healing and adds an ATK team buff, while the Eternal Xiranite gear set further boosts team damage through consistent Amp application. Stat priorities emphasize Will for stronger heals, Intellect for higher Ultimate Amp scaling, and Ultimate Gain Efficiency to ensure consistent buff uptime. The result is a build that keeps the team healthy and significantly increases the damage output of Cryo and Nature allies.

Insights

Core Mechanics

Xaihi’s Battle Skill Distributed DoS summons an Auxiliary Crystal that heals the controlled operator twice on Final Strike and grants an Arts Amp if the target is already at full HP.
Her Ultimate Stack Overflow provides a temporary Cryo Amp and Nature Amp to the entire team, scaling with Intellect up to a 30% bonus.
Once the Auxiliary Crystal exhausts its heals, her Combo Skill Stress Testing becomes available, dealing Cryo damage and applying Cryo Infliction.
Her first talent Execute Process further increases the Cryo damage taken by enemies afflicted with Cryo Infliction or Solidification.

Scaling

Xaihi’s healing scales with Will, making Will a top priority stat to boost her sustain and trigger the healing-to-Amp conversion reliably.
Her Ultimate Amp bonus scales with Intellect, so stacking Intellect directly improves her team buffing capabilities in the late game.
Early game investments focus on healing throughput and Energy regeneration to maintain Ultimate uptime, while late game builds prioritize maximizing Intellect and Amp potency.

Team Role

Xaihi operates as a dedicated background support. She is almost never used as the controlled operator; instead, she enables the main DPS by providing frequent heals, team-wide ATK or DMG buffs, and Cryo application. Her kit synergizes perfectly with Arts-heavy squads, particularly those relying on Cryo or Nature reactions. In a typical rotation, she deploys her Battle Skill to heal and potentially Amp the main carry, then triggers her Ultimate to grant additional elemental Amps. Her low cooldown Combo Skill helps maintain Cryo Infliction uptime, which further amplifies damage from Cryo DPS units. Because her healing and buffs scale with Will and Intellect, she fits smoothly into teams that need a sustain‑capable buffer without demanding on‑field presence.

Explanation

Chivalric Virtues is the ideal weapon because it directly boosts Will, increases treatment efficiency, and grants a team‑wide ATK buff on heal—perfect for a support who aims to both sustain and amplify.

The Eternal Xiranite gear set synergizes with her Amp‑centric kit; the additional DMG Dealt for teammates complements her existing buffs, and each piece contributes to faster Ultimate rotations and higher Intellect.

Detonation Unit serves as a strong alternative, trading some healing support for enemy debuffs, while Monaihe and Freedom to Proselytize are solid options if the best weapon is unavailable, especially to improve Energy economy.

Notes

The Eternal Xiranite set’s team-wide 16% DMG Dealt bonus triggers each time Xaihi applies Amp through her skills, providing near‑constant uptime.
Prioritize Will and Intellect pieces to simultaneously improve her healing potency and the strength of her Ultimate’s Amp.
