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 endgame support build focuses on maximizing Xaihi's team-wide utility. Chivalric Virtues amplifies her Will-based healing and grants an ATK buff to the whole party, while the Eternal Xiranite set turns her constant Amp and status applications into a +16% DMG Dealt buff for allies. The stat priorities on Will, Intellect, and Ultimate Gain Efficiency ensure her heals hit hard, her Ultimate provides stronger Cryo and Nature Amp, and her key buffs are active as often as possible.

Explanation
Chivalric Virtues is the top pick because it scales with Xaihi's Will and adds an ATK buff for the entire team, making her healing and amplifying roles even stronger.
Detonation Unit is a solid alternative because it raises her main and secondary attributes while debuffing enemies to take more Arts damage, which helps reaction-heavy teams.
Dreams of the Starry Beach is a great free-to-play choice thanks to its enhanced Healing and extra Intellect for her Ultimate Amp.
Monaihe is viable for players who want more Ultimate uptime, though it lacks additional supportive effects beyond raw attributes.
Notes
- Chivalric Virtues increases Xaihi's Will and grants a team-wide ATK buff whenever she heals, directly boosting her supportive power.
- Eternal Xiranite's set bonus grants the whole team +16% DMG Dealt for 15s whenever Xaihi applies Amp, Protected, Susceptibility, or Weakened, which her kit does constantly.
- Each gear piece provides Will, Intellect, and Ultimate Gain Efficiency, improving her heals, Ultimate Amp, and overall rotation uptime.
early gamesupportearly_gamef2pfree_weaponhealertreatmentstarter
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.

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.
Build Insights
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.
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.
Character Notes
Xaihi is a 5-star Cryo Supporter who operates best as a teammate rather than the main operator. She combines strong single-target healing with powerful team buffs: her Battle Skill creates an Auxiliary Crystal that heals on Final Strikes and converts overhealing into Arts Amp, her Combo Skill applies Cryo Infliction, and her Ultimate grants the whole party Cryo and Nature Amp based on her Intellect. She shines in Cryo and Nature compositions that rely on reactions and sustained damage output, while also offering utility through cleanse and damage taken debuffs.
Playstyle
- Use the Auxiliary Crystal to heal the controlled operator twice, then trigger the Combo Skill to apply Cryo Infliction to enemies.
- Try to keep allies near max HP so the crystal's heal becomes an Arts Amp instead of a normal heal.
- Pop her Ultimate before a burst window to give Cryo and Nature attackers extra Amp for 12 seconds.
- Position Xaihi as a support Teammate and avoid making her the primary damage dealer.
Strengths
- Excellent team-wide support with heals, Amp buffs, and a global DMG Dealt buff when paired with Eternal Xiranite.
- Strong synergy with Cryo and Nature teams through her Ultimate Amp and Cryo Infliction application.
- Low Ultimate cost allows frequent uptime of her team buffs.
- Her talent increases Cryo damage enemies take, making her valuable in infliction-focused comps.
Weaknesses
- Almost no personal damage potential, so she should not be used as the main operator.
- Her Arts Amp from the Battle Skill only triggers when the target is already at max HP, requiring careful timing.
- Utility is heavily tied to her Ultimate, so she needs Intellect and energy stats to maximize value.
Team Guide
bestcryo_teamsolidification_teamburst_team
A Cryo-focused team that powers Yvonne's Ice damage by keeping enemies Cryo-inflicted. Xaihi sustains the party and boosts Arts, Cryo, and Nature damage, while Gilberta's Nature application and Tangtang's Cryo help trigger Solidification repeatedly.
Explanation
Xaihi's Ultimate and Combo Skill grant Cryo Amp and extra Cryo damage taken, making Yvonne's hits much stronger.
Gilberta applies Nature Infliction; combined with Cryo from Xaihi, Yvonne, and Tangtang, it reliably triggers Solidification for crowd control and bonus damage.
Tangtang adds Arts Susceptibility and helps reapply Cryo, letting Yvonne unload her Ultimate safely.
Strengths
- Extremely high Cryo uptime keeps enemies Solidified, reducing incoming pressure.
- Xaihi's healing keeps the controlled team healthy through long fights.
Weaknesses
- Relies on having Yvonne, a premium Ice carry, to reach full damage potential.
- Needs careful sequencing of Combo Skills to maintain Solidification uptime.
Rotation
- 1Open with Xaihi's Battle Skill to apply party buffs, then use Gilberta's Battle Skill to apply Nature Infliction.
- 2Use Yvonne's Final Strike, then her Battle Skill to trigger Solidification and begin charging her Ultimate.
- 3If Solidification triggers, follow with a basic attack to skip to Final Strike; cast Xaihi's Ultimate when available.
- 4Cast Yvonne's Combo Skill to reapply Solidification, then Xaihi's Combo Skill for Cryo Infliction.
- 5Use Tangtang's Combo Skill, then her Battle Skill to apply Arts Susceptibility onto enemies.
- 6Fire Tangtang's Ultimate for crowd control, then Yvonne's Ultimate; finish with a Dive Attack to proc Tangtang's Riot Bringer Talent.
Buff with Xaihi and Gilberta, trigger Solidification with Yvonne, then rotate through Combo Skills before Yvonne's Ultimate.
bestcryo_teamcryo_inflictionburst_team
Xaihi anchors a Cryo Infliction core for Last Rite, providing healing, Cryo Amp, and the extra Cryo stacks needed to reach the three-stack threshold. Tangtang and Fluorite add more Cryo and debuffs, letting Last Rite's Ultimate hit for massive damage.
Explanation
Xaihi's Ultimate buffs the team with Cryo Amp and her Combo Skill debuffs enemies while adding Cryo Infliction.
Tangtang spreads Cryo and Arts Susceptibility, while Fluorite adds another stack of Cryo Infliction to support Last Rite.
The guide also shows variants swapping in Ardelia or Perlica as extra support when facing different content.
Strengths
- Consistently reaches at least three Cryo Infliction stacks, enabling Last Rite's biggest damage windows.
- Xaihi's healing makes the team self-sufficient in long encounters.
Weaknesses
- Needs Last Rite for the main DPS role.
- Rotation is tight; mistiming Tangtang's or Fluorite's Combo Skills can delay Cryo stacks.
Rotation
- 1Start with Xaihi's Battle Skill, then Last Rite's Battle Skill.
- 2Use Tangtang's Final Strike to apply Cryo Infliction, then cast Last Rite's Battle Skill again without triggering Tangtang's Combo.
- 3Do another Final Strike with Tangtang for a second Cryo stack; cast Xaihi's Ultimate when it becomes available.
- 4Trigger Tangtang's Combo Skill for Whirlpool, Xaihi's Combo Skill for Cryo, and Fluorite's Combo Skill; follow with Tangtang's Battle Skill.
- 5Use Last Rite's Combo Skill to add Cryo Susceptibility, then her Ultimate; end with a Dive Attack to activate Tangtang's Riot Bringer Talent.
Apply Cryo Infliction with Xaihi, Tangtang, and Fluorite, then unleash Last Rite's Ultimate after stacking debuffs.
Team Insights
Xaihi works best as a sustain/support in Cryo-oriented compositions, where her healing, Cryo Infliction, and damage amplifiers directly feed the main carry. Pair her with Cryo DPS characters such as Yvonne or Last Rite, and add supports who can either provide Nature Infliction for Solidification or extra Cryo stacks. Her Combo Skill is also a reliable way to hit the three-stack Cryo Infliction requirement against tougher enemies.
Synergy Patterns
- Xaihi + Yvonne: Xaihi's Cryo Amp and healing let Yvonne stay aggressive, while Gilberta's Nature triggers Solidification.
- Xaihi + Last Rite: Xaihi's Combo Skill supplies crucial Cryo Infliction stacks and debuffs for Last Rite's burst.
- Xaihi + Tangtang: Tangtang's Arts Susceptibility and crowd control make Xaihi's DPS partner safer to deal damage.
- Xaihi + Fluorite: Fluorite adds another Cryo stack, easing the team's reaction requirements.
Tips
- Keep Xaihi's Ultimate handy for the carry's burst phase to maximize Cryo Amp uptime.
- Use Xaihi as the flexible sustain when the controlled operator needs healing.
- Line up Xaihi's Combo Skill before your carry's big damage window to add Cryo Infliction and debuffs.
