Fu Xuan in Honkai Star Rail

Fu Xuan is a 5-star Quantum unit in Honkai Star Rail hailing from the Path of Preservation. As such, here is an in-depth guide about Fu Xuan’s abilities, Eidolons, best Light Cones, and much more.

Fu Xuan is a very different kind of Preservation unit in Honkai Star Rail. Unlike Gepard, who directly applies a shield to the characters in the game, Fu Xuan reduces incoming damage, provides a damage boost, heals herself and the team, and deals damage to enemies.

Fu Xuan’s rerun banner will be featured alongside Boothill from May 29, 2024, to June 18, 2024. Therefore, if you manage to pull Fu Xuan, you should build her as soon as possible.

Here is all you need to know regarding Fu Xuan in the game.

Fu Xuan Light Cones in Honkai Star Rail

Fu Xuan’s best-in-slot Light Cone is a must-have for her

Fu Xuan’s best Light Cone in Honkai Star Rail is She Already Shut Her Eyes. This particular Light Cone increases the HP of the wearer by 24%-40% and the Energy Regeneration Rate by 12%-20%. Additionally, once the HP of the wearer is reduced, the damage output of all allies is enhanced by 9%-15% for 2 turns.

Lastly, all allies have their HP restored equivalent to 80% of the number that is lost. This Light Cone can only be obtained from the Event Wish Warp at Limited Times.

However, if you are looking for a more free-to-play option then Texture of Memories from Herta’s Store is an excellent option for Fu Xuan. Apart from that, Landau’s Choice and Day One of My New Life are pretty powerful 4-star options for Fu Xuan.

Best Relics and Planar Ornament for Fu Xuan in Honkai Star Rail

Fu Xuan is a defensive unit who scales off HP, which means her best-in-slot Relic set is going to be a mix of Longevous Discipline and Guard of Wuthering Snow. The set bonus for both these Relics has been provided below:

2-piece bonus (Longevous Discipline): HP increased by 12%

2-piece bonus (Guard of Wuthering Snow): Damage taken is reduced by 8%

The best Planar ornament set for Fu Xuan in Honkai Star Rail is Broken Keel. This is because it increases the Effect RES of the wearer by 10% and when it crosses the 30% mark, the CRIT DMG of the party is enhanced by 10%.

Best Fu Xuan Team comp in Honkai Star Rail

Fu Xuan is a defensive unit that focuses on damage mitigation. However, she can function in a wide variety of teams on account of her flexibility. In any case, if you are looking for the best team to go for then Fu Xuan pairs exceptionally well alongside Seele, Bronya, and Luocha.

However, you can also run a mono-Quantum team including Fu Xuan, Seele, Sparkle, and Silver Wolf. The damage potential of this team is massive and is quite well-rounded considering the kind of content that is available in the game right now.
