Fushuan Honkai Star Rail Guide: Talents, Eidolons & Synergies ~ Haplo Gaming Cook

How to Optimize Fushuan’s Kit – Best Relics, Cones & TeamsCharacter Overview

Fushuan is a Quantum-type support unit introduced in version 3.2 of Honkai: Star Rail. As a Preservation path character, her primary role is to protect the team through damage mitigation, survivability buffs, and HP restoration. Unlike traditional shielders, her toolkit revolves around redirection of incoming damage and self-healing mechanisms that make her a robust and self-sustaining tank, ideal for extended combat and multi-wave encounters.

Talents & Abilities Breakdown

Basic Attack: Quantum Strike

Fushuan's basic attack inflicts Quantum damage to a single enemy, scaling off 50% of her max HP.
Ideal for energy generation and triggering supportive effects.

Skill: Matrix of Precience

Redirects 65% of incoming damage (pre-shield calculation) from allies to Fushuan for 3 turns.
Allies under this effect gain:
- +6% of Fushuan’s max HP as additional HP.
- +12% Crit Rate.
Matrix dispels if Fushuan is knocked out.

Ultimate: Full-Spectrum Assault

Deals Quantum damage equal to 100% of Fushuan’s max HP to all enemies.
Activates a trigger count for her healing passive (linked to her Talent).

Talent: Misfortune Avoidance

While active, the team receives 18% less damage.
If Fushuan’s HP drops to 50% or below, she restores 90% of the HP she’s missing. This passive:
- Can’t trigger if she receives a fatal hit.
- Comes with 1 base charge, up to 2 max.

Technique: Tactical Barrier

Activates a 20-second team-wide shield before combat.
Prevents entry into battle when attacked.
Initiates the Matrix effect for 2 turns when battle begins.

Bonus Abilities (Traces)

A2 – Tactical Restoration: Using her skill while Matrix is active generates 20 energy.
A4 – Coordinated Healing: Her Ultimate heals allies by 5% of Fushuan's max HP + 133 flat.
A6 – Debuff Immunity: While Matrix is active, all allies resist crowd-control debuffs during the activation turn (once per Matrix use).

Eidolons: Strategic Enhancements

Fushuan's Eidolons offer powerful upgrades that reinforce her tanking role and expand her team support functions.

E1: Increases allies' Crit DMG by 30% while under the Knowledge effect.
E2: If an ally receives a fatal blow during Matrix, they are revived with 70% HP (1 use per battle).
E4: Fushuan generates 5 energy whenever an ally is attacked under Matrix.
E6: Tallies total HP lost by allies during Matrix. Her next Ultimate increases in damage by 200% of that tally (capped at 120% of her max HP). Tally resets post-Ultimate.

F2P Option: Heropyone

Boosts Effect Resistance and max HP scaling for added sustainability

Utility Pick: Landau’s Choice

+16% damage mitigation (+24% at S5)
Increases the chance of being targeted
Keeps Fushuan in the damage path and out of risk for DPS units

Optimal Relic Setups

Fushuan doesn’t benefit from a dedicated 4-piece set, so 2-piece combinations are optimal.

Best Combos:

2pc Longevous Disciple (Max HP +12%)
2pc Guard of Wuthering Snow (Damage Taken -8%)
2pc Messenger Traversing Hackerspace / Sprightly Vonwacq (Speed +6%)

Main Stats Recommendation:

Body: HP%
Feet: Speed (aim for at least 134 Speed)
Orb: HP%
Link Rope: Energy Regen Rate

Substats Priority:

Speed (minimum 134)
HP%
DEF%
Effect RES (especially for Broken Keel users aiming for 30%)

Best Planetary Ornament Sets

Choose based on team composition and Fushuan’s role in your lineup.

Broken Keel: +10% Effect RES, grants +10% Crit DMG to the team at 30% Effect RES
Fleet of the Ageless: +12% Max HP, teamwide +8% ATK at 120+ Speed
Sprightly Vonwacq: +5% Energy Regen Rate, +12% ATK to first position unit
Pan-Galactic Commercial Enterprise: +5% Energy Regen Rate, +10% buff to same-element allies

Team Synergy Recommendations

Fushuan works well across a range of teams due to her sustain role.

Ideal Team Compositions:

Crit-Based Teams: Leverages her Crit Rate and Crit DMG buffs
Multi-Wave Encounters: Matrix uptime and team HP regen at wave starts boost long-term fights
Non-HP-Draining DPS: Works better with characters who don’t excessively drain HP (unlike Blade or Xueyi)

Avoid Using Fushuan With:

HP-draining DPS as primary heal output may not keep up

Playstyle Tips & Advanced Strategy

Always open with Matrix before taking heavy AoE turns.
Time your Ultimate usage when HP tally is high to maximize AOE damage via E6.
Use speed boots to hit energy regen breakpoints for continuous healing uptime.
Focus substat upgrades on Speed, HP%, then DEF%.

Conclusion

Fushuan is a top-tier sustain character that fits seamlessly into most team compositions in Honkai: Star Rail. With her flexible damage redirection, strong scaling from max HP, and multi-purpose talents and eidolons, she enhances both team durability and consistency in combat. Whether you're engaging in tough Simulated Universe floors or prolonged Forgotten Hall battles, Fushuan ensures your team stays alive while contributing meaningfully to overall output.
