Tingyun Gameplay
Fu Xuan is a 5-star Quantum Preservation character who excels as a premium defensive support, protecting the team through damage mitigation, survivability buffs, and reliable self-sustain. Her kit revolves around activating Matrix of Prescience, allowing allies to redirect a large portion of incoming damage to Fu Xuan while gaining increased Max HP, CRIT Rate, and overall damage reduction. This playstyle allows her to provide exceptional team stability, especially during difficult boss fights and prolonged endgame battles.
Her combat performance heavily depends on properly maintaining Matrix of Prescience uptime. Once Fu Xuan activates her Skill, allies gain the Knowledge effect and benefit from her powerful defensive utility, significantly reducing the risk of sudden knockouts from high enemy burst damage. At the same time, Fu Xuan absorbs a large portion of the team’s incoming damage and relies on her Talent’s automatic self-healing to sustain herself throughout combat. This makes her one of the most reliable sustain units for Memory of Chaos and other high-difficulty content.
Fu Xuan’s Ultimate further improves her performance by dealing Quantum AoE damage while granting 1 additional trigger count for her Talent’s HP Restore effect, increasing her survivability even more. Her kit encourages a playstyle focused on timing, defensive consistency, and proper Ultimate management. She synergizes best with hypercarry teams and fragile DPS units that benefit from strong protection, allowing them to focus entirely on maximizing damage while Fu Xuan handles the team’s survival.
Fu Xuan Trace Priority
| Trace | Priority |
| Talent | ★★★★★ (Top) |
| Skill | ★★★★★ (Top) |
| Ultimate | ★★★ (Medium) |
| Basic Attack | ★ (Low) |
Fu Xuan’s Skill is her highest priority because it activates Matrix of Prescience, the core of her entire kit. This ability allows allies to redirect a large portion of incoming damage to Fu Xuan while also granting increased Max HP, CRIT Rate, and powerful team survivability through the Knowledge effect. Leveling this trace significantly improves her overall defensive utility and support value, making it essential for maximizing her effectiveness.
Her Talent is the second priority. It provides global damage reduction for the team through Misfortune Avoidance and allows Fu Xuan to automatically restore her own HP when her health falls below a certain threshold. Upgrading this trace greatly improves her consistency as a premium sustain unit, making it a key part of her defensive utility in prolonged endgame battles.
Fu Xuan’s Ultimate should be leveled next, as it deals Quantum AoE damage while granting 1 additional trigger count for her Talent’s HP Restore effect. This improves her survivability and helps maintain her defensive consistency during extended fights. While useful, its overall impact is slightly lower compared to her Skill and Talent, since it is not the primary source of her team protection.
Her Basic Attack is the lowest priority. It contributes minimal damage compared to her other abilities and is rarely important in optimized rotations. Since Fu Xuan’s kit revolves around team protection, sustain, and defensive utility, investing resources here provides the least benefit.
Fu Xuan Best Light Cones
To select the ideal Light Cone for Fu Xuan, evaluate your build against these three tactical needs rather than simply choosing by rarity:
- Maximizing HP-Based Survivability: A large portion of Fu Xuan’s effectiveness comes from her Max HP scaling, since her Skill, Ultimate, and Talent all rely heavily on HP to improve both her personal sustain and overall team protection. Because of this, Light Cones that increase HP, improve survivability, or strengthen her defensive consistency will significantly enhance her overall performance.
- Improving Team Sustain and Damage Mitigation: Fu Xuan’s main role is protecting the team through damage redistribution, damage reduction, and reliable self-healing. Light Cones that provide additional healing, improve incoming damage control, or strengthen her ability to stay alive while absorbing team damage greatly improve her value as a premium Preservation support and one of the strongest sustain units in the game.
- Enhancing Utility and Long Fight Consistency: As a sustain-focused character, Fu Xuan performs best in prolonged battles where maintaining consistent protection is essential. Light Cones that improve Energy Regeneration, defensive uptime, or provide stable utility across extended fights help maximize her impact in Memory of Chaos, Pure Fiction, and other difficult endgame content.

Fu Xuan Relics, Ornaments & Stats Priority
1. Relics
The 2-piece Longevous Disciple + 2-piece Guard of Wuthering Snow set is the best choice for Fu Xuan, as it improves her Max HP scaling and overall survivability. Since her kit revolves around protecting the team through damage redistribution, self-sustain, and defensive utility, this set perfectly enhances her overall support value and consistency in battle. As alternative options, the 2-piece Longevous Disciple + 2-piece Messenger Traversing Hackerspace and 4-piece Longevous Disciple are also strong choices, as they improve her Speed, rotation consistency, and overall sustain performance, allowing her to maintain stronger team protection in extended fights.

2. Planar Ornaments
Broken Keel is the best Planar Ornament for Fu Xuan, as it directly improves her Effect RES while also increasing the entire team’s CRIT DMG, perfectly matching her role as a premium defensive support. Since Fu Xuan’s kit revolves around survivability, team protection, and supporting hypercarry DPS units, this set provides the most reliable and efficient performance in extended fights. However, depending on your build and stat needs, you may also choose Fleet of the Ageless. Fleet of the Ageless increases Max HP and also buffs the entire team’s ATK, making it a strong alternative for improving both her personal sustain and overall team utility while maintaining stable performance across different scenarios.
