endgame support

supporthealerbuffer
Xaihi excels as a Cryo support, providing strong heals and team-wide buffs. Her Ultimate and Battle Skill grant Amp to Cryo and Nature allies, while her Combo Skill applies Cryo Infliction. She is highly valuable in Infliction-centric team comps.
This endgame build maximizes Xaihi's healing and team buffing capabilities. Chivalric Virtues provides a team-wide ATK buff on heal, while the Eternal Xiranite set amplifies party damage when she applies Amp or status effects. Focus on Will, Intellect, and Ultimate Gain Efficiency to ensure frequent Ultimate uptime and strong heals. This build is optimal for Infliction-centric team compositions.

Insights

Core Mechanics

  • Battle Skill Distributed DoS summons an Auxiliary Crystal that heals the controlled operator on Final Strikes, scaling with Will. If at full HP, it grants an Arts Amp instead.
  • Combo Skill Stress Testing becomes available after two heals, dealing Cryo DMG and applying Cryo Infliction.
  • Ultimate Stack Overflow provides temporary Cryo and Nature Amp to the whole team, with additional scaling from Intellect (capped at 30%).
  • Talent Execute Process boosts Cryo DMG taken by enemies hit with Cryo Infliction or Solidification from her Combo Skill.

Scaling

  • Healing scales with Will, while Ultimate Amp scales with Intellect. Prioritizing both stats maximizes her support output.
  • Early game she functions well as a pure healer; late game her buffing and debuffing become more impactful in team rotations.
  • Her effectiveness increases significantly with team synergy, especially with Cryo and Nature DPS characters.

Team Role

Xaihi is best used as a support teammate, not the main operator. She provides consistent healing via her Auxiliary Crystal and boosts team damage through her Ultimate's Cryo and Nature Amp. Her Combo Skill applies Cryo Infliction, enabling reactions and boosting Cryo DMG via her talent. She fits well in teams focusing on Cryo and Nature elements, especially those that can capitalize on Infliction mechanics. Her low ultimate cost (80) allows frequent uptime. As a Support class character, she excels when paired with a strong controlled operator who can trigger her healing and benefit from the Amp.

Explanation

Chivalric Virtues is chosen because its Medicant essence boosts treatment efficiency, and after healing, it grants the entire team an ATK buff, synergizing with Xaihi's role.
Eternal Xiranite set provides Will and Intellect for better healing and Amp, plus Ultimate Gain Efficiency for faster ultimate rotation.
Alternatives like Detonation Unit or Dreams of the Starry Beach can be used if Chivalric Virtues is unavailable, prioritizing debuffing or healing respectively.

Notes

  • The Eternal Xiranite set's bonus increases team DMG dealt when Xaihi applies Amp or other effects, amplifying her support role.
  • Redeemer Armor is recommended as the armor piece for its Intellect and Ultimate Gain Efficiency substats.
