Fu Xuan Best Relic Build HSR: Best Light Cones, Teams, and Materials
Mastering Fu Xuan requires a deep understanding of her unique damage-mitigation mechanics and HP-scaling capabilities to ensure your team survives the toughest challenges in Honkai: Star Rail. As the Master Diviner of the Xianzhou Luofu’s Divination Commission, she stands as a premier S+ tier Preservation unit capable of solo-sustaining an entire party through damage redirection and significant offensive buffs.

Fu Xuan changed the meta of Honkai: Star Rail upon her release, introducing a “tanking” style that moves away from traditional shielding. Instead of providing a flat shield like Gepard or Aventurine, Fu Xuan utilizes the Matrix of Prescience to absorb a massive portion of the damage her allies would otherwise take. This guide provides the definitive look at her best relic builds, light cones, and team compositions to maximize her potential in the current endgame.
Fu Xuan Overview: The Master Diviner
Fu Xuan is a 5-star Quantum character following the Path of Preservation. Unlike other Preservation units that focus on preventing damage via shields, Fu Xuan excels at damage redirection and mitigation. When her Skill is active, she takes 65% of the damage intended for her teammates, effectively acting as a lightning rod for the party.
One of the primary reasons Fu Xuan is considered a “must-pull” or high-tier unit is her ability to compress multiple roles into a single slot. She is a sustainer who provides:
- Damage Mitigation: Reduces the overall damage the team takes.
- Damage Redirection: Prevents squishy Hunt or Erudition characters from being one-shot.
- Offensive Buffing: Increases the team’s Max HP and, most importantly, their Crit Rate.
- Crowd Control Resistance: Her traces allow the team to ignore a debuff instance, which is vital against bosses like Kafka or the Swarm Disaster.
- Self-Sustain: Her Talent allows her to heal back nearly all her missing health when she drops below 50% HP, provided she has charges available.
Because she scales entirely off Max HP, building her is relatively straightforward but requires hitting specific “breakpoints” for Speed and Energy Regeneration to ensure her Matrix of Prescience never expires.
Fu Xuan Skills & Trace Priority
Understanding Fu Xuan’s kit is essential for managing her “Matrix of Prescience” uptime. Her gameplay loop generally follows a “Skill-Basic-Basic” rotation to remain Skill Point (SP) positive while keeping her buffs active.
Skill Breakdown
- Basic Attack: Novaburst Deals Quantum DMG equal to 25%–55% of Fu Xuan’s Max HP to a single enemy. While not her primary focus, the fact that it scales with HP means Fu Xuan can contribute non-negligible chip damage and help with Quantum Weakness breaking.
- Skill: Known by Stars, Shown by Hearts This is the core of her kit. It activates the Matrix of Prescience for 3 turns. While active, allies distribute 65% of the DMG they receive to Fu Xuan. Furthermore, all allies gain the “Knowledge” effect, which increases their Max HP by 3%–6.6% of Fu Xuan’s Max HP and their Crit Rate by 6%–13.2%.
- Ultimate: Woes of Many Morphed to One Deals Quantum DMG equal to 60%–108% of Fu Xuan’s Max HP to all enemies. More importantly, it grants 1 trigger count for her Talent’s HP Restore effect. Managing these counts is the difference between Fu Xuan surviving a boss’s ultimate or falling in battle.
- Talent: Bleak Breeds Bliss While Fu Xuan is active, she applies “Misfortune Avoidance” to the team, reducing all damage taken by 10%–19.6%. When her own HP falls to 50% or less, she automatically restores 80%–92% of her missing HP. She starts the battle with 1 charge and can hold a maximum of 2 charges (increased via her Ultimate).
Trace Priority and Major Traces
To maximize her efficiency, you should prioritize her traces in the following order:
- Skill: Increases the Crit Rate buff and the HP buff for the team.
- Talent: Increases the team-wide damage reduction and her own self-healing percentage.
- Ultimate: Increases her AoE damage and the minor heal she provides to the team.
- Basic Attack: Lowest priority, as she is not a primary damage dealer.
Major Traces (Bonus Abilities):
- Taiyi, the Macrocosmic (A2): Regenerates 20 extra Energy when using her Skill while the Matrix is active. This is crucial for maintaining her 135 Energy Ultimate.
- Dunjia, the Metamystic (A4): When her Ultimate is used, it heals all other allies by 5% of Fu Xuan’s Max HP plus 133. This helps top off the chip damage allies take that isn’t redirected to Fu Xuan.
- Liuren, the Sexagenary (A6): If an enemy applies Crowd Control debuffs while Matrix of Prescience is active, all allies resist all CC debuffs applied during that action. This can trigger once per Skill activation.
Ascension and Trace Materials
To reach Level 80 and max out her Traces, you will need to farm materials primarily found on the Xianzhou Luofu.
Ascension Materials Table
| Level | Materials Required | Credits |
|---|---|---|
| 20 | Artifex’s Module x5 | 4,000 |
| 40 | Artifex’s Module x10 | 16,000 |
| 50 | Artifex’s Cogwheel x6, Nail of the Ape x3 | 40,000 |
| 60 | Artifex’s Cogwheel x9, Nail of the Ape x7 | 80,000 |
| 70 | Artifex’s Gyreheart x6, Nail of the Ape x20 | 160,000 |
| 80 | Artifex’s Gyreheart x9, Nail of the Ape x35 | 308,000 |
Trace Materials
For her Trace leveling, you will need the Endurance of Bronze, Iron Guard’s Spilled Blood, and Safeguard of Amber series, which are the standard Preservation materials. Additionally, she requires the Regret of Infinite Ochema (dropped by Phantylia the Undying) for high-level Trace nodes and Tracks of Destiny.
Best Relic and Planar Ornament Build
The goal for a Fu Xuan build is to reach a high enough HP pool to survive redirected damage while maintaining enough Speed to refresh her Skill and Ultimate.
Recommended Relic Sets
The most consistent build for Fu Xuan is a combination of 2-piece sets rather than a full 4-piece set.
-
2pc Longevous Disciple + 2pc Guard of Wuthering Snow (Best Overall)
- 2pc Longevous: Increases Max HP by 12%.
- 2pc Guard: Reduces DMG taken by 8%.
- Why it works: This combo provides the perfect balance of raw HP (which scales her buffs and damage) and damage reduction (which makes her “Effective HP” much higher).
-
2pc Messenger Traversing Hackerspace + 2pc Longevous Disciple
- 2pc Messenger: Increases Speed by 6%.
- Why it works: If you are struggling to hit the 134 Speed breakpoint through sub-stats alone, the Messenger set provides a necessary boost.
Planar Ornaments
- Broken Keel (Best for Support)
- Increases the wearer’s Effect RES by 10%. When Effect RES is 30% or higher, all allies’ CRIT DMG increases by 10%.
- Fu Xuan already gains Effect RES from her minor traces, making it very easy to hit the 30% requirement. This adds more offensive value to her kit.
- Fleet of the Ageless (Best for HP/ATK Buffing)
- Increases Max HP by 12%. When Speed is 120 or higher, all allies’ ATK increases by 8%.
- This is a great alternative if your DPS scales better with ATK than Crit DMG (e.g., Kafka or Black Swan, though Fu Xuan is less ideal for DoT teams).
Main Stat and Sub-stat Priorities
| Gear Piece | Main Stat |
|---|---|
| Chest | HP% |
| Feet | Speed |
| Planar Sphere | HP% |
| Link Rope | Energy Regeneration Rate |
Sub-stat Priority:
- Speed: Aim for at least 134 to act twice in the first cycle of Memory of Chaos.
- HP%: The higher her HP, the more damage she can soak. 8,000+ HP is the “safe” zone for endgame content.
- Effect RES: Essential for avoiding debuffs that might prevent her from using her Ultimate or refreshing her Skill.
- DEF%: While she scales with HP, having around 1,500–2,000 DEF significantly reduces the damage she takes from redirected hits.
Top Light Cones for Fu Xuan
Fu Xuan’s Light Cone options vary significantly between premium and F2P choices.
- She Already Shut Her Eyes (5-star Signature) This is her Best-in-Slot (BiS) by a wide margin. It increases Max HP by 24% and Energy Regeneration Rate by 12%. Furthermore, when the wearer’s HP is reduced, it increases the DMG of all allies by 9% for 2 turns. It also restores HP to all allies at the start of every wave.
- Texture of Memories (5-star F2P) Available in Herta’s Store, this is the best F2P option. 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 the damage they take. It significantly increases Fu Xuan’s personal survivability.
- Landau’s Choice (4-star) This Light Cone increases the likelihood of the wearer being attacked (aggro) and reduces the damage they take by 16%–24%. This is excellent for keeping damage away from your teammates, though it puts more strain on Fu Xuan’s self-healing.
- Day One of My New Life (4-star) Increases the wearer’s DEF by 16%–24% and increases All-Type RES for all allies by 8%–12%. This is a solid “set it and forget it” support option that buffs the whole team’s bulk.
Best Team Compositions
Fu Xuan is a universal sustain unit, but she shines in specific archetypes that benefit from her Crit Rate buff and Quantum element.
1. Mono-Quantum Team
This is arguably Fu Xuan’s strongest team. By using only Quantum characters, you guarantee that Silver Wolf’s Skill will always implant a Quantum Weakness on the enemy.
- Sustain: Fu Xuan
- Main DPS: Seele or Qingque
- Support: Silver Wolf
- Support: Sparkle
In this composition, Fu Xuan provides the survivability and Crit Rate, Sparkle provides Crit DMG and Skill Points, and Silver Wolf handles debuffs and weakness implants.
2. Blade Hypercarry
Blade is a unique DPS because he wants to take damage to trigger his follow-up attacks, but he needs to stay alive. Fu Xuan is perfect for him because she allows him to take “reduced” damage (which still counts as a hit for his stacks) while increasing his Max HP, which he scales with.
- Sustain: Fu Xuan
- Main DPS: Blade
- Support: Bronya
- Support: Pela or Ruan Mei
Fu Xuan’s HP buff directly increases Blade’s damage output, making her a better choice for him than traditional shielders who might prevent him from losing HP.
3. F2P Friendly Sustain
Fu Xuan is powerful enough to carry even basic teams through difficult content. She can be slotted into any team that needs a defensive anchor.
- Sustain: Fu Xuan
- Main DPS: Dan Heng or Serval
- Sub-DPS: Trailblazer (Destruction)
- Support: Asta
In this F2P setup, Fu Xuan ensures the squishier 4-star characters can survive high-damage AoE attacks from bosses. Asta’s speed buff also helps Fu Xuan take more turns, which generates more energy for her healing Ultimate.
Summary of Fu Xuan’s Role
Fu Xuan remains one of the most valuable pulls in Honkai: Star Rail due to her ability to negate one-shot mechanics. By focusing on a build that emphasizes HP%, Speed, and Energy Regeneration, you ensure that the Master Diviner can foresee every threat and keep your team standing through the most grueling battles the Xianzhou Luofu and beyond have to offer.
