• Dive attack: Basic attack performed in mid-air becomes a dive attack that deals Cryo DMG to nearby enemies.
• Finisher: Basic attack performed near a Staggered enemy becomes a finisher that deals massive Cryo DMG and recovers some SP.

Battle skill - Distributed DoS

• Summons an Auxiliary Crystal that orbits the operator for a while. When the controlled operator performs a Final Strike on the enemy, the Auxiliary Crystal restores the said operator's HP. This effect can trigger 2 times. The attribute of Will increases the amount of HP treatment. When the controlled operator is already at Max HP when triggering the HP restoration, grant the said operator a temporary Arts Amp instead. This effect cannot stack.

Team synergy and role

Xaihi is a Supporter who has extremely good synergy with the Cryo team. She has good buffs for this team (Cryo Amp) and can also heal them. She's got good synergy with the following:

• Last Rite (Cryo)
• Yvonne (Cryo)
• Gilberta (Nature)
• Snowshine (Cryo)
• Estella (Cryo)

Is Xaihi worth using?

When you create a Cryo team, you will most likely use Last Rite and Yvonne - therefore, if you want to really have a solid Cryo team, you will use Xaihi. She's worth it - she grants an outstanding amount of Cryo Amp, on top of the healing she already provides.
