Best Teams

Last Rite Last Rite Xaihi

Xaihi Xaihi Fluorite

Fluorite Fluorite Ardelia

Ardelia Ardelia Last Rite team that uses Xaihi and Fluorite to apply extra Cryo Inflictions. Avoid using Fluorite Battle Skill as Last Rite wants as many Cryo Inflictions as possible. Ardelia

Ardelia Ardelia can be replaced with other buffers like Perlica

Perlica Perlica or Gilberta

Gilberta Gilberta as well. Yvonne

Yvonne Yvonne Last Rite

Last Rite Last Rite Xaihi

Xaihi Xaihi Fluorite

Fluorite Fluorite Yvonne team that focuses on increasing Yvonne’s damage as much as possible. Note: Last Rite helps enable Yvonne, but Yvonne does not enable Last Rite. Xaihi is the main buffer for the team, so focusing her build on Intellect and Ultimate Gain is key.

Hypernova Auto Hypernova Auto (Some Intellect)

Chivalric Virtues 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. If healing becomes less important, Xaihi's Bi S may change to an alternative that maximizes her buffing potential. Detonation Unit

Detonation Unit Detonation Unit provides Main Stat Boost (not Intellect), but the passive effect grants Secondary Attribute (Intellect for Xaihi). This along with a passive effect that debuffs enemies with Arts Damage Taken makes this a very strong option for buffing. Dreams of the Starry Beach

Dreams of the Starry Beach Dreams of the Starry Beach is simply an option because it grants the most Intellect, which will increase Xaihi's Ultimate Amp. Freedom to Proselytize

Freedom to Proselytize 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. Monaihe

Monaihe Monaihe just grants some Ultimate Gain Efficient and Hypernova Auto

Hypernova Auto Hypernova Auto is just a Purple Weapon with Intellect. There aren't great options in the Purple/Gold category if your focus is to buff your team.

Eternal Xiranite is used for increasing the damage of the team after Xaihi

Xaihi Xaihi uses her Ultimate (which provides Cryo and Nature Amp). Since we want to optimize the Amp of her Ultimate, this build prioritizes building Intellect and Ultimate Gain Efficiency. Eternal Xiranite Auxiliary Arm

Eternal Xiranite Auxiliary Arm Eternal Xiranite Auxiliary Arm sacrifices a little bit of Intellect for more Will (Main Stat), but we want to prioritize Intellect. Note: You only need one

Eternal Xiranite Eternal Xiranite set per team, so if you run a team with multiple buffers ( Gilberta

Gilberta Gilberta / Ardelia

Ardelia Ardelia / Perlica

Perlica Perlica ), you can use a healing set on Xaihi. However, even running multiple sets can improve the buff uptime, so it's not a complete waste to overlap the Gear Set Effect.

How to Play

Xaihi is a straightforward support character who enhances the Controlled Operator's performance, particularly those who deal Arts Damage.

Core Loop

Use Xaihi's **Battle Skill**.

Switch to your Controlled Operator and hit enemies with their **Final Strike**.

This triggers healing (or applies Arts Amp if HP is full) and activates Xaihi's **Combo Skill**.

Combo Skill Management

Her Combo Skill deals damage and applies Cryo Infliction. It has a moderate cooldown, so ensure it is available before executing Final Strikes. To maximize effectiveness, try to hit enemies already affected by Cryo Infliction or Solidification; this triggers her Combat Talent, increasing Cryo Damage against them.

Ultimate Utility

Use her Ultimate before spending other units' Cryo and Nature Skills to maximize their impact. If you have unlocked her 2nd Combat Talent, her Ultimate can also remove Solidification from allies, serving as a crucial cleanse to prevent unnecessary deaths.

Release Date

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.
