Fu Xuan is a 5-star Quantum character following the Path of Preservation. Unlike traditional shielders like Gepard or March 7th, Fu Xuan protects her team through damage mitigation and redirection. She is widely considered one of the most “comfy” units in the game, capable of solo-sustaining a team through the hardest content, including Memory of Chaos and Pure Fiction. This guide covers the optimal relic sets, light cones, and team compositions to maximize her potential as the head of the Divination Commission.
Fu Xuan Overview
Fu Xuan is a 5-star Quantum Preservation character who excels at damage redirection and team-wide buffs. Her kit is designed around the “Matrix of Prescience,” a field she creates using her Skill. While this field is active, a significant portion of the damage dealt to her allies is transferred to her instead. This unique mechanic prevents allies from being one-shot by powerful boss attacks, making her more reliable than shielders in scenarios where enemies have high shield-break capabilities.
Unlike traditional tanks, Fu Xuan provides offensive utility. She increases the team’s Max HP and, more importantly, their CRIT Rate. This allows players to build their DPS characters with a higher focus on CRIT DMG, knowing Fu Xuan will fill the gap in their CRIT Rate needs. She is also self-sufficient; her Talent allows her to automatically heal herself when her HP drops below a certain threshold, provided she has charges gained from her Ultimate.
Key points to remember about Fu Xuan’s role:
- She absorbs a portion of the damage dealt to allies, making her unique in the Preservation path.
- She provides a significant CRIT Rate buff and Max HP increase to the entire team through her Skill.
- She possesses a built-in “crowd control” (CC) resist for the whole team, which is invaluable against enemies that freeze or stun.
Fu Xuan Skills and Traces
Understanding Fu Xuan’s skill priority is essential for efficient resource management. Her Matrix of Prescience is the core of her kit, requiring high uptime to ensure the team remains protected. Prioritize leveling her Skill and Talent first for maximum survivability and team buffs. Her Ultimate is essential for refreshing her self-healing charges, which keeps her alive while she absorbs the team’s damage.

Trace Priority
- Skill (Known by Stars, Shown by Hearts): This is your primary source of damage reduction and the CRIT Rate buff. Maximizing this ensures your team takes the least amount of damage possible.
- Talent (Bleak to Bliss): This governs Fu Xuan’s self-healing and the team’s passive damage reduction. Higher levels mean Fu Xuan is harder to kill.
- Ultimate (Woes of Many Purged): While the damage is nice, the primary goal is the HP Restore trigger. Leveling this increases her AoE damage contribution.
- Basic Attack (Novascintilla): This is the lowest priority, used only to generate Skill Points.
Fu Xuan’s Bonus Abilities are also vital. Liuren Oracle allows her to resist Crowd Control debuffs for the entire team once per Skill activation. Dunjia Thaumaturgy heals the rest of the team slightly when she uses her Ultimate, helping to top off chip damage that isn’t redirected. Taiyi Divination provides extra Energy when the Matrix is active, aiding her Ultimate rotation.
Fu Xuan Ascension and Trace Materials
To reach Level 80 and max out her Traces, Fu Xuan requires materials found primarily on the Xianzhou Luofu. You will need to farm the Stagnant Shadow in Scalegorge Waterscape and the Crimson Calyx for Preservation materials.
Ascension Materials
| Level | Materials Required | Credits |
|---|---|---|
| 20 | Artifex’s Module x5 | 4,000 |
| 40 | Artifex’s Cogwheel x6, Nail of the Ape x3 | 16,000 |
| 50 | Artifex’s Cogwheel x9, Nail of the Ape x7 | 40,000 |
| 60 | Artifex’s Gyreheart x7, Nail of the Ape x20 | 60,000 |
| 70 | Artifex’s Gyreheart x20, Nail of the Ape x35 | 128,000 |
Trace Leveling Materials
To fully upgrade Fu Xuan’s abilities, you will need the following totals:
- Artifex’s Module / Cogwheel / Gyreheart: Dropped by Entranced Ingenia enemies on the Xianzhou Luofu.
- Endurance of Bronze / Safeguard of Amber / Safeguard of Amber: Obtained from the Bud of Preservation Crimson Calyx.
- Regret of Infinite Ochema: Dropped by the Echo of War: Divine Seed (Phantylia the Undying).
- Tracks of Destiny: Obtained from weekly Simulated Universe rewards, Nameless Honor, or limited-time events.
Best Relics and Light Cones for Fu Xuan
Building Fu Xuan requires a balance of HP, Speed, and Energy Regeneration. Because she scales almost entirely off her Max HP, traditional DEF-focused Preservation builds are less effective on her. The goal is to make her pool of health as large as possible while ensuring she moves fast enough to generate energy and refresh her Skill.
Best Relic Sets
The 2pc Longevous Disciple and 2pc Guard of Wuthering Snow combo is the gold standard for tanking. This combination provides a direct 12% boost to her Max HP and a flat 8% reduction in damage taken. Since Fu Xuan takes a massive amount of redirected damage, the flat damage reduction from the Guard set is often more valuable than additional HP.
Alternatively, players can use 2pc Messenger Traversing Hackerspace for a 6% Speed boost if they are struggling to hit Speed breakpoints (typically 134 or higher).
Planar Ornaments
- Fleet of the Ageless: Increases Max HP by 12%. If Fu Xuan’s Speed is 120 or higher, all allies receive an 8% ATK boost. This is her most consistent option.
- Broken Keel: Increases Effect RES by 10%. If Effect RES is 30% or higher, all allies receive a 10% CRIT DMG boost. This is excellent for further increasing the team’s offensive output, especially since Fu Xuan already provides CRIT Rate.
Recommended Stats
| Gear Piece | Main Stat | Substat Priority |
|---|---|---|
| Head | HP (Fixed) | HP% > SPD > Effect RES > DEF% |
| Hands | ATK (Fixed) | HP% > SPD > Effect RES > DEF% |
| Body | HP% | SPD > Effect RES > DEF% |
| Feet | SPD | HP% > Effect RES > DEF% |
| Sphere | HP% | SPD > Effect RES > DEF% |
| Link Rope | Energy Regeneration Rate | HP% > SPD > Effect RES |
Energy Regeneration Rate on the Link Rope is critical for maintaining Ultimate frequency. Without an ERR rope, Fu Xuan may struggle to refresh her Talent charges fast enough in aggressive fights, leading to her eventual downfall.
Best Light Cones
- She Already Shut Her Eyes (5-Star Signature): This is her best-in-slot Light Cone. It increases Max HP and Energy Regeneration Rate. Additionally, when the wearer’s HP is reduced, it increases the DMG of all allies. It even restores HP to all allies at the start of every wave.
- Texture of Memories (5-Star F2P): Available in Herta’s Store. It increases Effect RES and provides a shield based on Max HP when the wearer is attacked. If the wearer already has a shield, it reduces damage taken. This is a fantastic free-to-play option that enhances her survivability.
- Landau’s Choice (4-Star): Increases the likelihood of the wearer being attacked and reduces damage taken. This helps Fu Xuan draw single-target aggro away from squishy allies while providing flat damage reduction.
- Day One of My New Life (4-Star): Increases the wearer’s DEF and increases DMG RES for all allies. While DEF is less efficient on Fu Xuan than HP, the team-wide damage resistance stacks with her passive for incredible mitigation.
Top Fu Xuan Team Compositions
Fu Xuan is a versatile unit that fits into almost any team requiring a sustain character. However, she shines brightest in teams that benefit from her CRIT Rate buff or her specific element.
Mono-Quantum Team
Fu Xuan is the cornerstone of the Mono-Quantum team, enabling Silver Wolf’s weakness implant to be 100% consistent against any enemy.
- Main DPS: Seele or Qingque
- Support: Silver Wolf
- Support: Sparkle
- Sustain: Fu Xuan
In this composition, Silver Wolf ensures the enemy always has a Quantum weakness. Sparkle provides Skill Points and massive CRIT DMG buffs, which synergize perfectly with the CRIT Rate Fu Xuan provides. This team is capable of brute-forcing almost any content in the game.
Hypercarry Sustain Team
Fu Xuan is highly effective in Hypercarry teams that need both protection and offensive buffs. Characters like Jing Yuan or Dr. Ratio, who rely heavily on landing critical hits, benefit immensely from her presence.
- Main DPS: Jing Yuan
- Support: Tingyun
- Support: Sparkle or Asta
- Sustain: Fu Xuan
Jing Yuan, in particular, appreciates Fu Xuan’s CC resist. If Jing Yuan is CC’d (frozen or stunned), his Lightning-Lord cannot act. Fu Xuan’s Matrix of Prescience prevents this from happening once per skill use, ensuring the team’s damage output remains consistent.
Dual DPS Compositions
Because Fu Xuan provides team-wide buffs rather than single-target ones, she is an excellent choice for teams running two damage dealers.
- DPS 1: Blade
- DPS 2: Jingliu
- Support: Pela or Ruan Mei
- Sustain: Fu Xuan
Blade benefits from the Max HP increase Fu Xuan provides, as his damage scales with his own HP. While Fu Xuan prevents some of the damage Blade wants to take to build his stacks, the overall stability and CRIT buffs she provides often outweigh this slight anti-synergy.
Fu Xuan remains one of the most impactful pulls a player can make in Honkai: Star Rail. By investing in her HP and Speed, you ensure that your team can weather any storm the Stellaron Hunters or the Antimatter Legion throw your way.
