Xaihi Build Guide

Last Rite Xaihi Estella Fluorite

Last Rite team that uses Xaihi, Estella and Fluorite to apply extra Cryo Inflictions. Avoid using Fluorite Battle Skill as Last Rite wants as many Cryo Inflictions as possible. You can replace Fluorite with Ardelia for Arts Susceptibility and Corrosion or Perlica for Electrification. Snowshine can also replace Estella for an alternate method of Cryo Infliction.

Yvonne Xaihi Alesh Gilberta

Yvonne team that focuses on increasing Yvonne’s damage as much as possible.

Best Weapons

• Best-in-Slot: Chivalric Virtues
• Alt: Freedom to Proselytize
• Alt: Detonation Unit

Chivalric Virtues is an amazing option for healers that increases the Team ATK. It’s the best option for Xaihi if you want to balance healing and utility.

Freedom to Proselytize is Xaihi’s Signature. It offers amazing stats for her, but it just increases her healing potential, without increasing the team damage.

Detonation Unit focuses on increasing the team's damage. It requires triggering Arts Burst on enemies, which isn’t hard since you’ll have other Cryo Operators with Xaihi.

Gear

• Gear Set: LYNX
• Armor:LYNX Cuirass
• Gloves: LYNX Gloves
• Kit 1: LYNX Aegis Injector
• Kit 2: Eternal Xiranite Auxiliary Arm

LYNX greatly increases Xaihi’s Healing Potential. For better healing, you can swap LYNX Gloves for LYNX Gauntlets

Battle Skill = Ultimate > Combo Skill > Basic Attacks

Leveling her Battle Skill and Ultimate increases the Team Utility, so it’s a high priority for Xaihi. Combo and Basics are just for damage, and they are a low priority compared to your DPS’ skills.

• P1 Agile Execution
• P2 Link Aggregation
• P3 Mapping Node
• P4 Grayscale Release
• P5 Controlled Recursion

Xaihi Potentials focuses on increasing the utility that Xaihi provides to your team. Most of them are just numbers, but Potential 3 allows Xaihi to apply Cryo Infliction to multiple enemies when using her Combo Skill.

Keep in mind that vertically investing in Arknights Endfield is not recommended and you should treat these as a bonus damage/utility for your Operator.

Xaihi is really straightforward, use her Battle Skill and let your Controlled Operator hit enemies with their Final Strike. This heals them or, if their HP is already maxed out, apply Arts Amp to them. So ideally you want your Controlled Operator to be someone that deals Arts Damage.

This also activates Xaihi’s Combo Skill, which deals damage and applies Cryo Infliction to enemies. It has a moderate cooldown, so make sure it’s available before hitting enemies with Final Strikes. Also, try to hit enemies that are already under Cryo Inflictions or Solidification to trigger her Combat Talent and increase the Cryo Damage against them.

Use her Ultimate before spending other units’ Cryo and Nature Skills or, if you unlocked her 2nd Combat Talent, to remove Solidification from your allies and avoid unnecessary deaths.

Xaihi will release on January 22nd, 2026 along with the release of Arknights: Endfield.

Xaihi is a Standard Operator, meaning they are permanently available through the gacha system.
