Honkai Star Rail: Best build for Fu Xuan – Relics, Light Cones, Eidolons, and Abilities

The Master Diviner of the Divination Commission in the Xianzhou Luofu is one of many characters available for Honkai: Star Rail players to unlock. At level five rarity, Fu Xuan is the Preservation Path and uses the Quantum combat type. This is an incredible support character who can tank allies’ hits and still deal decent damage. Here’s the best build for Fu Xuan in Honkai: Star Rail, including the best Relics, Light Cones, Eidolons, and Abilities.

How to build the best Fu Xuan in Honkai: Star Rail

Light Cones

There are a few decent Light Cones for Fu Xuan, but one that’s especially perfect for her. A good four-star Light Cone would be Landau’s Choice, which makes her more likely to get attacked, but the damage she takes is reduced. Fu Xuan is a great defensive support player, so she needs to stay alive while tanking hits for the party.

For a five-star Light Cone, you could try Texture of Memories, which increases her Effect RES, and if attacked with no Shield, she gains Shield equal to a minimum of 16% of her max HP for two turns. But by far, Fu Xuan’s best Light Cone is She Already Shut Her Eyes. It’ll increase her max HP by 24-40% and Energy Regeneration Rate by 12-20%. When HP is reduced, all her allies’ damage increases for two turns, and at the start of each wave, allies’ HP restores by a decent amount.

Relics

Fu Xuan can work with a few different Relic Sets, but I highly recommend you mix two of these three sets:

• Longevous Disciple: Increases max HP by 12%.
• Messenger Traversing Hackerspace: Increases SPD by 6%.
• Guard of Wuthering Snow: Reduces DMG taken by 8%.

I believe at least having two Guard of Wuthering Snow, alongside a double set of either Longevous Disciple or Messenger Traversing Hackerspace, will work best. You want to make sure Fu Xuan takes the least amount of damage, while also either having better HP or SPD. You’ll find all these Relic Sets at their designated Cavern of Corrosion.

Abilities

The most important ability in Fu Xuan’s arsenal is her Skill Known by Stars, Shown by Hearts. Using this Skill allows damage done to other team members to be distributed mostly toward Fu Xuan, making her a great tank. This Skill lasts for three turns, so you’ll want to focus on upgrading this in the Traces screen.

The two other most important Abilities Fu Xuan has is her Talent and Ultimate. The former allows allies to take less damage whenever she’s not knocked down, and Fu Xuan will restore some HP when she reaches 50% health or less. The latter deals an enormous amount of Quantum damage equal to her HP to all enemies. Fu Xuan’s Basic ATK is the last thing you should be focusing on when looking to upgrade her Traces.

Eidolons

Gaining Eidolons is really up to chance, and whether you get Fu Xuan multiple times in future banners, but they can still provide great benefits. I’d say that the best Eidolons have to be Optimus Felix (level 2) and Omia Vita (level 6).

Optimus Felix is easier to achieve. When Matrix of Prescience is active (done by her Skill), and a team member is struck by a killing blow, they won’t be knocked down, and 70% of their max HP is restored. This can save your life and is an incredible Eidolon.

If you manage to reach level 6 with Omia Vita, this also has to do with Matrix of Prescience. When active, it’ll accumulate the total HP lost by your team members during battle. Fu Xuan’s Ultimate damage will increase by 200% of the total HP lost, which is a wild ability to have.
