Xaihi

SS

endgame 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 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.

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

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.
