As a seasoned Honkai: Star Rail player, I've always been drawn to characters who redefine their role. Fu Xuan, the 5-star Quantum Preservation unit from the Xianzhou Luofu, is one such character. She isn't a traditional shielder like Gepard or March 7th. Instead, she uses her Matrix of Prescience to absorb a portion of the damage her allies take, while also boosting their Max HP and CRIT Rate. It's a unique support kit that makes her invaluable in tough fights. In this guide, I'll share my personal build for Fu Xuan, covering light cones, relics, team comps, and skill priorities. Even in 2026, with many new characters and light cones added to the game, Fu Xuan remains a top-tier preservation unit. Let's dive in.

Best Light Cones for Fu Xuan
When choosing a light cone for Fu Xuan, remember that her damage and team HP boost scale off her Max HP. So HP is the priority stat. Her signature 5-star light cone, She Already Shut Her Eyes, is far and away the best option. At level 80, it provides a base HP of 1,270, and its skill increases her Max HP by 24% and Energy Regeneration Rate by 12%. Moreover, when she loses HP, all allies deal 9% more damage for two turns. Finally, at the start of each wave, it restores HP to all allies equal to 80% of the difference between their Max HP and current HP. This light cone perfectly complements her kit.

If you don't have her signature, here are some alternatives I've tested:
| Light Cone | Rarity | Key Benefits |
|---|---|---|
| Texture of Memories | 5-star (F2P) | Base HP 1,058; +8% Effect RES; shield equal to 16% Max HP when attacked without shield; 12% DMG reduction with shield. |
| We Are Wildfire | 4-star | Base HP 740; on battle start, allies take 8% less DMG for 5 turns; restores HP equal to 30% of HP difference. |
| Landau's Choice | 4-star | Base HP 952; increases chance to be attacked but reduces DMG taken by 16%. |
Most Preservation light cones give DEF, which isn't ideal for Fu Xuan. As the game evolves, I hope more HP-scaling Preservation light cones will be released, but for now, these are your best bets.
Best Relics, Ornaments, and Stats for Fu Xuan

For relics, the Longevous Disciple set is my go-to. A 4-piece set gives 12% Max HP and, when Fu Xuan is hit or loses HP, increases her CRIT Rate by 8% for two turns, stacking up to two times. This synergizes with her Traces that also boost CRIT Rate. Alternatively, you can run 2-piece Longevous Disciple and 2-piece Genius of Brilliant Star for a 10% Quantum DMG boost, if your CRIT stats are already solid.
For Planar Ornaments, I prefer Fleet of the Ageless: 12% HP and, if SPD is 120+, all allies get 8% ATK. Another option is Broken Keel: 10% Effect RES and, if Effect RES is 30%+, all allies get 10% CRIT DMG. Choose based on your team's needs.
| Stat Type | Priority |
|---|---|
| Main Stats | HP%, Effect RES, Energy Regeneration Rate |
| Sub-Stats | HP%, Effect RES, CRIT DMG/CRIT Rate, Quantum DMG |
When farming, aim for HP, Effect RES, and Energy Regeneration first. CRIT and Quantum DMG are nice bonuses since she can deal decent damage with her HP scaling.
Best Team Comps for Fu Xuan

Fu Xuan isn't a team centerpiece; she's a flexible support who fits into many compositions. Her damage reduction and offensive buffs make her a great addition to any team. I typically run her with a main DPS, a healer, and a sub-DPS or damage-boosting support. For example: Seele (DPS), Fu Xuan (support), Bronya (support), and Luocha (healer). In easier content, you can drop the healer and run a hypercarry team for maximum damage, but it's risky. A mono-Quantum team with Seele, Silver Wolf, Fu Xuan, and a healer is also viable. Mono-Quantum teams are particularly strong because Fu Xuan's Quantum element synergizes with Silver Wolf's weakness implant, and Seele can capitalize on the debuffs. However, this comp requires careful speed tuning.
Skill Priority for Fu Xuan

When leveling Fu Xuan's Traces, prioritize the minor nodes that increase HP. Then focus on her Skill, which is the core of her kit, followed by her Talent. Her Ultimate is next, as it contributes decent damage. Finally, level her Basic Attack last. Her Basic Attack is rarely used, so you can leave it at level 1 if resources are tight. Here's my recommended order:
-
Skill
-
Talent
-
Ultimate
-
Basic Attack
Fu Xuan is a unique and powerful Preservation character. With an HP-focused build, she can protect her team while boosting their offense. Even in 2026, she remains a solid choice for any account. I hope this guide helps you get the most out of her. Happy trailblazing! 🚂
