Xaihi

early game support

supporthealerbuffercryo_applicatoramp_support

The source guide lists Xaihi at S+ tier. She excels as a support who buffs Cryo and Nature teams with powerful Amp effects from her Ultimate and Battle Skill, while also providing team-wide healing, Cryo Infliction, and a talent that increases Cryo damage taken. Her low Ultimate energy cost and strong utility make her highly valuable in reaction-focused compositions.

This early game build gives Xaihi a strong foundation using the free Dreams of the Starry Beach weapon and the Mordvolt Resistant gear set. The weapon boosts her Intellect and healing power, while the armor set adds Will and a situational 30% Treatment Effect bonus when HP drops below half. Together they increase her survivability, healing output, and Ultimate Amp value, making her a reliable support for newly formed teams.

Insights

Core Mechanics

Distributed DoS summons an Auxiliary Crystal that heals the controlled operator twice on Final Strike; if the target is already at max HP, the heal converts into a temporary Arts Amp.
Stress Testing becomes available after the crystal's two heals are used and applies Cryo Infliction, enabling Cryo reactions and combos with her first talent.
Stack Overflow grants the entire team Cryo Amp and Nature Amp for 12 seconds, with the bonus scaling off Intellect up to a 30% bonus cap.
Her talent, Execute Process, adds a Cryo Damage Dealt debuff to enemies hit by her Combo Skill when they are afflicted with Cryo Infliction or Solidification.

Scaling

Healing strength scales with Will, so stacking Will improves her sustain.
Ultimate Amp scaling uses Intellect, raising the flat Amp bonus up to a 30% extra cap.
Her support value remains strong throughout the game, though she contributes little personal damage and is best used as a dedicated teammate.

Team Role

Xaihi is designed as a backline support that should be played as a Teammate rather than the Controlled Operator. She rotates between healing the active operator, triggering Cryo Infliction on enemies, and dropping her Ultimate to buff all Cryo and Nature damage dealers. She pairs exceptionally well with Cryo DPS units and teams built around infliction reactions, as her talent amplifies the damage those teams deal. She also offers defensive utility through her second talent, which cleanses Cryo Infliction and Solidification from allies during her Ultimate.

Explanation

Dreams of the Starry Beach is chosen because it is easily obtained for new players and directly improves the two stats Xaihi needs most: Will for healing and Intellect for Ultimate Amp.

Mordvolt Resistant's Will increase supports her base healing, while the below-50% HP healing bonus gives her more reliable sustain during early game encounters.

The set pieces also grant Intellect, so Xaihi's Ultimate will still provide a decent Amp bonus before later gear is available.

Notes

Dreams of the Starry Beach is a free 6-star weapon that increases Xaihi's healing and Intellect, making it excellent for early progression.
Mordvolt Resistant provides a flat Will bonus and an extra 30% Treatment Effect when Xaihi is below 50% HP, letting her heal more effectively in tough fights.
This set's Will and Intellect boosts align perfectly with Xaihi's scaling, helping both her heals and Ultimate Amp from the start.
