Xaihi Best Team Compositions

Yvonne is arguably the best DPS for Xaihi. Yvonne is unable to apply her own Cryo Infliction. Xaihi can fill this role instead, enabling Yvonne to get more Solidification application off on enemies. As a Cryo and Nature Amplifier, Xaihi is poised to maximize Yvonne's DPS output, making her one of the best DPS options in the game with a pocket-Xaihi.

Last Rite is a Cryo Striker Operator who wants to consume large amounts of Cryo Infliction as much as possible. Whenever there are 3 Cryo Infliction stacks present, she will Shatter them for massive damage, while restoring Ultimate Energy for herself. One of the limiting factors for Last Rite's DPS potential is the amount of Cryo Inflictions the rest of the team can provide for her, which Xaihi does quite handily. Not only that, but Xaihi also provides additional Amp bonuses to further boos Last Rite's DPS, leading to many triggers of her Combo Skill for maximum damage.

Snowshine can apply emergency HP Treatment to the Controlled Operator when their HP drops below a specifc threshold, and with the LYNX armor set, she can also provide a sizable damage reduction. In addition to this, she acts as a Cryo Infliction enabler, and even applies Solidification through the zone of her Ultimate. She works well on Mono-Cryo teams featuring Yvonne in particular, due to the aforementioned issues Yvonne faces by not being able to apply her own Cryo Inflictions.
As a fellow HP Treatment and Cryo Infliction enabler, it may seem counter-intuitive at first to play them both together, but Xaihi wants to overheal with her battle skill to grant the Arts Amplification, so Snowshine really pairs well with Xaihi. Double-y so in endgame content where survivability is important.
