Xaihi’s Role Explained
Xaihi is designed as a hybrid support character who combines three important functions:
Healing Support
Xaihi provides consistent healing that helps teams survive longer battles, especially in difficult encounters where enemy damage pressure is high. Unlike burst-only healers, Xaihi can maintain team stability while continuing to provide offensive support.
Cryo Application
As a Cryo Supporter, Xaihi can apply Cryo effects during combat. This makes her especially effective in teams that rely on Cryo damage dealers, elemental reactions, and Arts-based damage strategies.
Team Damage Enhancement
The biggest reason to build Xaihi is her ability to increase the team's overall damage output. By combining Cryo application and support effects, she creates stronger damage windows for the main DPS.

Xaihi Skills Breakdown
Basic Attack
Upgrade Priority: Low
Xaihi’s Basic Attack is not the main focus of her kit. Since she functions primarily as a support character, most of her value comes from skill effects rather than direct damage output.
Resources should be invested into her support abilities first.
Combat Skill
Xaihi’s Combat Skill is one of the key parts of her gameplay. It allows her to provide consistent team support while contributing to Cryo-based strategies.
Main functions:
- Applies Cryo effects
- Supports team rotations
- Improves combat consistency
This skill should be upgraded early because it directly affects Xaihi’s contribution during normal combat.
Ultimate Skill
Xaihi’s Ultimate is the centerpiece of her kit. It provides the strongest support effect and should be prioritized when building her.
The Ultimate is especially valuable during:
- Boss fights
- Enemy break windows
- Main DPS burst phases
*Recommended usage: Activate Xaihi’s Ultimate before switching to your main damage dealer to maximize the team's damage window.
Xaihi Skill Priority
Xaihi’s main purpose is supporting the team rather than dealing direct damage. Her upgrade priority should focus on skills that improve healing consistency, Cryo application, and team-wide utility.
Recommended upgrade order:
| Priority | Skill | Reason |
|---|---|---|
| 1 | Ultimate Skill | Provides the strongest support effect and improves team damage windows |
| 2 | Combat Skill | Core ability for Cryo application and consistent support |
| 3 | Passive Talents | Improves overall performance and skill efficiency |
| 4 | Basic Attack | Lowest priority because Xaihi is not a main DPS |
For most players, upgrading Xaihi’s Ultimate and Combat Skill first provides the biggest improvement in real combat situations.
Xaihi Build Guide
Xaihi is not designed to stay on the field for extended periods. Her ideal playstyle is a quick-support rotation:
- Enter the battlefield
- Apply Cryo effects and activate support abilities
- Trigger her Ultimate when the team is ready to deal damage
- Switch back to the main DPS
Because of this, Xaihi’s build should focus on improving her support uptime rather than maximizing personal damage.
Recommended Weapons for Xaihi
Signature Weapon
Xaihi’s signature weapon is the ideal choice because it is designed around her support-focused kit.
Benefits:
- Improves her support performance
- Helps maintain skill rotations
- Maximizes her value in Cryo teams
Alternative Weapons
For players without her signature weapon, prioritize weapons that provide:
- Energy regeneration
- Support bonuses
- Utility effects
| Weapon Type | Recommended Use |
|---|---|
| Signature Weapon | Maximum support performance |
| Energy-focused Weapon | Faster Ultimate rotation |
| F2P Support Weapon | Budget-friendly option |

Common Mistakes When Playing Xaihi
1. Keeping Xaihi on Field Too Long
Xaihi’s damage is not her main value. Avoid spending too much field time on basic attacks.
2. Using Ultimate Without DPS Setup
Her Ultimate provides the most value when combined with your team's damage window. Save it for important moments instead of using it immediately.
3. Ignoring Energy Recovery
Without enough energy regeneration, Xaihi may struggle to maintain consistent support uptime.

Her combination of:

makes her a valuable addition to many team compositions. Players who enjoy Cryo teams or need a strong support character will find Xaihi worth investing in.
