Xaihi

early game support

supporthealerbufferampcryo

Xaihi is a premier support thanks to the strong Amp buffs her Ultimate and Battle Skill hand out, especially to Cryo and Nature allies. On top of that she keeps the whole party topped up with heals and can apply Cryo Infliction, which sets up powerful elemental reactions for her teammates.

A budget-friendly starting point for new players. Dreams of the Starry Beach is a free 6-star weapon that boosts Xaihi's healing and Intellect, while the Mordvolt Resistant set raises her Will and her healing throughput. It gives a usable healer and support core without needing any hard-to-find gear.

Insights

Core Mechanics

Auxiliary Crystal: her Battle Skill summons a crystal that heals the controlled operator whenever a Final Strike lands, up to two triggers, scaled by Will.
If the crystal's heal would push the operator past max HP, the excess becomes an Arts Amp instead, so keeping the active unit healthy converts healing into extra damage.
Once the crystal's two heals are spent, her Combo Skill becomes available and deals Cryo damage while applying Cryo Infliction.
Her Ultimate gives party-wide Cryo and Nature Amp, combining a flat base with a bonus that scales off Intellect and caps at 30%.
Her Execute Process talent makes Combo Skill hits raise the Cryo damage taken by enemies affected by Cryo Infliction or Solidification.

Scaling

Healing strength grows with Will, while the extra Amp provided by her Ultimate grows with Intellect, so both stats drive her support value.
She shines most in dedicated Cryo or Nature teams where her Amps land on damage dealers who can use them.
Her late-game value climbs further when allies reliably apply Cryo Infliction, letting her Execute Process talent amplify team damage.

Team Role

Xaihi is a backline support who is best left as a teammate rather than the controlled operator. Her Battle Skill sends out an Auxiliary Crystal that heals the active unit after Final Strikes and converts overflow healing into an Arts Amp, so she passively boosts whoever is on the field. When those heals are used up, her Combo Skill fires Cryo damage and Cryo Infliction, opening reaction windows for the team. Her Ultimate layers Cryo and Nature Amp on the entire squad, with the bonus portion scaling off Intellect, making her a natural fit beside Cryo or Nature damage dealers. She pairs especially well with supports who already run the Eternal Xiranite set, since she can then invest everything into Intellect and Ultimate Gain for bigger Amps and faster Ultimate cycles. Teams built around Infliction benefit most from her Execute Process talent, while Freeze Protocol adds a defensive cleanse against Solidification and Cryo Infliction.

Explanation

Mordvolt Resistant's Will boost and low-HP healing bonus keep her effective while players are still progressing.

Move toward the Chivalric Virtues build once stronger weapons and gear become available.

Notes

Dreams of the Starry Beach is free for newer players, which makes this setup very accessible.
Mordvolt Resistant raises Will and adds a healing bonus when the wearer drops below half HP.
Infliction and Treatment Efficiency take priority on the weapon's essence.
