What’s the best Honkai Star Rail Fu Xuan build?

Fu Xuan is a five-star character who deals quantum damage and treads the path of The Preservation. Characters from The Preservation path have powerful defensive capabilities and excel at protecting their allies, so despite her small stature, Lady Fu is a tank character.

Her abilities all scale based on her max HP, so that’s something to consider when building her. As well as max HP, we recommend investing in defense and quantum damage bonus.

What’s the best light cone for Fu Xuan?

All Honkai Star Rail characters have their own light cone that compliments their personal skills, and Fu Xuan is no different. Her signature light cone is She Already Shut Her Eyes is the perfect pick as it boosts her max HP and energy regeneration, as well as her team’s damage output.

As this is a limited five-star light cone, it can be pretty hard to get your hands on. In this case, We Are Wildfire is a good four-star option, as well as any other Preservation light cones that you have lying around.

Light code Effect How to obtain
She Already Shut Her Eyes Increases Fu Xuan’s max HP by 24% and her energy regeneration rate by 12%. When Fu Xuan’s HP is decreased, increases the damage of all allies by 9% for two turns. At the beginning of each wave, restores HP equal to 80% of HP already lost by Fu Xuan herself for team Event warp
We Are Wildfire At the start of the battle, the damage dealt to all allies decreases by 8% for five turns. At the same time, immediately restores HP to all allies equal to 30% of the respective HP difference between Fu Xuan’s max HP and current HP Echo of War rewards, Forgotten Hall light cone store
Defense When Fu Xuan unleashes her ultimate, she restores HP by 18% of her max HP Stellar warp

What are the best relics for Fu Xuan?

Currently, Genius of Brilliant Stars is the only relic set that boosts quantum damage. It also bypasses enemy defense when your target is weak to quantum damage. As such, this is the best way to boost Fu Xuan’s personal damage.

Alternatively, Guard of Wuthering Snow helps with damage reduction, HP restoration, and energy restoration, which are all great assets to Fu Xuan’s tanky kit. Longevous Disciple also has potential, either as a two-piece set for increased max HP, or a full four-piece set to boost Fu Xuan’s crit rate whenever she loses HP (which is a lot).

Fleet of the Ageless is the best set of planar ornaments for Fu Xuan as it increases her ever-important max HP.

What are Honkai Star Rail Fu Xuan’s abilities?

As a walker of the path of Preservation, Fu Xuan’s abilities are built to protect her fellow teammates, but she also has the ability to deal significant quantum damage of her own.

Active skills:

Skill Effect
Basic attack: Novaburst Fu Xuan deals quantum damage equal to 25% of her max HP to a single enemy
Skill: Known by Stars, Shown by Hearts Fu Xuan activates the Matrix of Prescience, via which other team members distribute 65% of the damage they receive (before it is mitigated by shields) to Fu Xuan for three turns. While affected by the Matrix of Prescience, all team members gain the knowledge effect, which increases their crit rate by 6% and their max HP by 3% of Fu Xuan’s max HP. The Matrix of Prescience dispells when Fu Xuan is knocked down.
Ultimate: Woes of Many Morphed to One Fu Xuan deals quantum damage equal to 60% of her max HP to all enemies and obtains one trigger count for her talent’s HP restore effect

Passive skill:

Skill Effect
Talent: Bleak Breeds Bliss While Fu Xuan is still active in battle, she applies Misfortune Avoidance to the entire team. This means that allies take 10% less damage. When Fu Xuan’s current HP falls to 50% of her max HP or less, this triggers HP restore, restoring her HP by 80% of the amount of HP she is currently missing. This effect doesn’t trigger if she receives a killing blow. This effect possesses one trigger count by default and can have a maximum of two trigger counts


Technique Effect
Of Fortune Comes Fate Fu Xuan grants a barrier for her whole team lasting for 20 seconds. This barrier can block all enemy attacks, and the team won’t enter battle when attacked. Fu Xuan automatically activates the Matrix of Prescience when entering battle while the barrier is active, which lasts for two turns


Trace Effect
Taiyi, the Macrocosmic When Matrix of Prescience is active, Fu Xuan regenerates 20 extra energy when she uses her skill
Dunjia, the Metamystic When Fu Xuan uses her ultimate, she heals all other allies by an amount equal to 5% of her max HP plus 133
Liuren, the Sexagenary If a target enemy applies crowd control debuffs to allies while the Matrix of Prescience is active, all allies will resist all crowd control debuffs applied by the enemy target during the current action. This effect can only trigger once. When Matrix of Prescience is activated again, the number of times this effect can trigger will reset
