Skills

Basic Novaburst

Deals Quantum DMG equal to 25% of Fu Xuan's Max HP to a single enemy. Fu Xuan's basic attack uniquely scales off her HP pool rather than ATK, which means heavy HP investment directly boosts even her baseline damage output, though she will rarely use this in practice over her Skill.

25% of Max HP
Skill Known by Stars, Shown by Hearts

Activates Matrix of Prescience for 3 turns. While active, other team members distribute 65% of the damage they receive (before Shield mitigation) to Fu Xuan instead. All team members gain the Knowledge effect: Max HP increases by 3% of Fu Xuan's Max HP and CRIT Rate increases by 6%. If Fu Xuan is knocked down, the Matrix is dispelled, making her survival the team's highest priority.

65% DMG redirected
Ultimate Woes of Many Morphed to One

Deals Quantum DMG equal to 60% of Fu Xuan's Max HP to all enemies, scaling purely off her massive HP pool. Upon using the Ultimate, Fu Xuan also obtains 1 additional trigger count for the HP Restore effect granted by her Talent, effectively storing an extra safety net for surviving burst damage windows.

60% Max HP, AoE
Talent Bleak Breeds Bliss

While Fu Xuan is alive, the entire team receives Misfortune Avoidance: all allies take 10% less DMG at all times. When Fu Xuan's current HP falls to 50% or less of her Max HP, an HP Restore triggers and she recovers 80% of her missing HP. This cannot trigger on a killing blow. The effect starts with 1 trigger count and caps at 2. Extra charges can be gained via her Ultimate.

10% team DMG reduction
Technique Of Fortune Comes Fate

After using the Technique, all team members receive a Barrier lasting 20 seconds in the overworld. This Barrier blocks all enemy attacks and prevents the team from entering battle when attacked. If the team enters battle while the Barrier is active, Fu Xuan automatically activates Matrix of Prescience at the start of combat for 2 turns, getting the protection up before anyone can take a hit.

#1
She Already Shut Her Eyes
She Already Shut Her Eyes
Her signature and best-in-slot. Increases Max HP and Energy Regen Rate, then triggers a team-wide DMG buff whenever Fu Xuan's HP is reduced. Also heals all allies at the start of each wave. Synergizes perfectly with her kit's HP-scaling mechanics and frequent HP drops from absorbing team damage.
Signature
#2
Moment of Victory
Moment of Victory
Strong alternative. Boosts Fu Xuan's DEF significantly and increases her taunt value so enemies prefer to target her. When she is attacked, her DEF increases even further. Excellent for absorbing redirected damage without dying.

#3
Texture of Memories
Texture of Memories
Increases Effect RES (helping to hit the 30% threshold for Broken Keel) and provides a Shield when attacked. While the Shield is active, incoming damage is further reduced. A good option if you already own it.

Landau's Choice
Landau's Choice
4-star accessible option that reduces damage taken and increases taunt. Low investment ceiling but consistent. Great for players who do not yet own a premium 5-star Preservation cone.

Day One of My New Life
Day One of My New Life
Provides DEF% and grants all allies a DMG RES boost, which stacks with Fu Xuan's own 10% team reduction from her Talent. Universally available 4-star budget pick that contributes to team durability.

Longevous Disciple (2pc) + Guard of Wuthering Snow (2pc)
The top cavern combination. Longevous Disciple's 2-piece bonus adds 12% Max HP, directly empowering Fu Xuan's HP-scaling skills, damage absorption, and the HP she shares with allies through Knowledge. Guard of Wuthering Snow's 2-piece adds 8% DMG reduction when HP is 50% or below, creating an extra safety layer during exactly the window when her Talent restore is about to trigger.

Longevous Disciple (2pc) + Messenger Traversing Hackerspace (2pc)
Alternative pairing. Messenger's 2-piece bonus adds 6% SPD, which helps Fu Xuan act more frequently so she can refresh Matrix of Prescience before it expires. Prioritize this if your Guard of Wuthering Snow pieces have poor substats.
2pc + 2pc

Longevous Disciple (2pc) + Sacerdos' Relived Ordeal (2pc)
Another viable combination. Sacerdos' 2-piece provides 8% SPD, which is the largest speed bonus available from cavern sets. Use if you can hit a meaningful speed breakpoint that allows an extra action cycle within the Matrix duration window.

Broken Keel
Broken Keel
Fu Xuan's best planar set. As long as her Effect RES is 30% or higher (achievable through traces and substats alone), the entire team gains 10% CRIT DMG. This is a free team-wide buff that stacks on top of her Skill's CRIT Rate bonus, making her one of the best CRIT-support sustain characters in the game.
2-piece Best in slot

Fleet of the Ageless
Fleet of the Ageless
Strong alternative. Adds 12% Max HP to Fu Xuan's stat line and, when her Speed reaches 120 or higher, grants all allies 8% ATK. The HP bonus directly benefits all of her HP-scaling mechanics. Slightly worse than Broken Keel in most DPS-focused teams but better for teams that don't benefit from CRIT DMG.

Best Teams for Fu Xuan

Fu Xuan fits into virtually any team as the sustain slot. She contributes more than just survival: her 6% CRIT Rate Knowledge buff and 10% CRIT DMG from Broken Keel passively amplify every DPS on the team.

Jingliu
Main DPS
Bronya
Harmony / Buffer
Pela

Fu Xuan
Sustain / CRIT Buffer
Jingliu consumes the whole team's HP for her Transcendence buffs. Fu Xuan's HP redistribution and large personal HP pool let teammates dip low safely, triggering Jingliu's bonuses without risking knockdowns. Bronya advances Jingliu's actions while Pela shreds DEF for consistent damage.

Blade thrives when his HP is low since it empowers his Hell Blade stacks. Fu Xuan's damage redirection means Blade's teammates naturally drop to lower HP thresholds more often, fueling his kit. Fu Xuan also keeps everyone alive through the controlled HP drain that Blade's synergy demands.

Eidolons

E 1
Dominus Pacis
The Knowledge effect now also increases CRIT DMG by 30% in addition to the base CRIT Rate bonus. This transforms Fu Xuan from a CRIT Rate buffer into a full CRIT buffer, adding meaningful multiplier value for every DPS on the team without any additional investment.
High Pull Value
E 2
Optimus Felix
If any team member is struck by a killing blow while Matrix of Prescience is active, all allies who would have been knocked down during that action will not be knocked down, and 70% of their Max HP is immediately restored. This effect can trigger once per battle. A safety net that effectively prevents wipes in scenarios that would otherwise end a run.
Game Changer
E 3
Apex Nexus
Skill level +2 (up to a maximum of Lv. 15) and Talent level +2 (up to a maximum of Lv. 15). Directly upgrades her two most important abilities: Matrix of Prescience duration and magnitude from Skill, and the DMG reduction and HP restore from Talent.
Solid Upgrade
E 4
Fortuna Stellaris
When other allies under Matrix of Prescience are attacked, Fu Xuan regenerates 5 Energy. In teams that face frequent attacks, this can meaningfully accelerate her Ultimate cycle, granting more trigger count charges for her Talent's HP restore and more AoE Quantum damage windows.
Good Passive
E 5
Arbiter Primus
Ultimate level +2 (up to a maximum of Lv. 15) and Basic ATK level +1 (up to a maximum of Lv. 10). Modest improvements to secondary parts of her kit. The Ultimate level increase raises her HP-scaling AoE damage, though Fu Xuan's role is rarely about damage output.
Incremental
E 6
Omnia Vita
Once Matrix of Prescience is activated, it tallies all HP lost by team members during the current battle. Fu Xuan's Ultimate DMG increases by 200% of this HP loss tally, capped at 120% of her Max HP. The tally resets and re-accumulates after each Ultimate use. In endgame content where her team absorbs massive damage, this makes her Ultimate a meaningful damage contributor on top of her defensive utility.
Massive Upgrade

Major Traces

Taiyi, the Macrocosmic
Ascension 2
When Matrix of Prescience is active, Fu Xuan will regenerate 20 extra Energy when she uses her Skill. This dramatically shortens her Ultimate cycle during extended combat, allowing more frequent AoE Quantum damage and additional trigger count charges for her Talent's HP restore, making sustained fights significantly safer.
Dunjia, the Metamystic
Ascension 4
When Fu Xuan's Ultimate is used, all other allies are healed by an amount equal to 5% of Fu Xuan's Max HP plus 133. This transforms her Ultimate from a pure damage tool into a supplemental team heal, giving her rare hybrid value as a sustain that can top off allies after periods of heavy redirection without using a dedicated healer.
Liuren, the Sexagenary
Ascension 6
If an enemy applies Crowd Control debuffs to allies while Matrix of Prescience is active, all allies will resist all CC debuffs applied by that enemy during the current action. This effect can trigger once, and resets each time Matrix of Prescience is reactivated. Effectively grants pseudo-CC immunity for the team during Matrix windows, invaluable in content with frequent freezes, stuns, or imprisonment.

Frequently Asked Questions

Fu Xuan does neither directly. Her Matrix of Prescience redirects 65% of incoming ally damage to herself before it is applied, so her teammates never take the full hit. Her Talent then auto-restores her own HP when she drops below 50%, keeping her alive through the absorbed damage. Her Ascension 4 trace adds a small heal to all allies when she uses her Ultimate. She does not provide shields at all. Her survivability comes from HP, DEF, and controlled damage absorption.
Fu Xuan's skills scale directly off her Max HP: her Basic ATK deals 25% Max HP damage, her Ultimate deals 60% Max HP AoE damage, the HP bonus she shares with allies via Knowledge is 3% of her Max HP, and the HP Restore from her Talent restores 80% of her missing HP, so a larger pool means more restored. DEF% is still valuable since it reduces the damage she takes from redirected hits, but HP% almost always provides a larger overall benefit and should be prioritized on the Body piece first.
If Fu Xuan is knocked down while Matrix of Prescience is active, the Matrix is immediately dispelled. From that point on, teammates absorb full damage again with no redirection. This is why keeping Fu Xuan alive is the team's top priority. She must survive to maintain the protection that lets everyone else survive. Build her with sufficient HP and DEF, and prioritize leveling her Skill and Talent to maximize her personal durability.
30% or higher. This is the threshold required to activate the Broken Keel planar ornament's team-wide 10% CRIT DMG bonus. Fortunately, Fu Xuan's trace bonuses alone contribute 10% Effect RES, and running Texture of Memories or investing in Effect RES substats makes 30% easy to reach. Hitting this number is almost always worth it since the CRIT DMG buff is a permanent team passive with no ongoing upkeep.
Yes, Fu Xuan is one of the best sustain units for all endgame content modes. In Memory of Chaos her passive CRIT Rate and CRIT DMG buffs increase team damage every cycle with zero action cost. In Apocalyptic Shadow her damage redirection ensures DPS characters survive the massive burst hits that define that mode. Her Ascension 6 CC resistance trace is particularly valuable in Pure Fiction waves that frequently apply freeze or imprisonment effects.
E1 is excellent. Adding 30% CRIT DMG to the Knowledge effect makes her a stronger team buffer than most dedicated support characters. E2 is a true game-changer: the once-per-battle knockdown prevention essentially gives the entire team an extra life, which can rescue failed runs in the most punishing endgame content. E3 upgrades her two most important skills. E4 through E6 are incremental for a sustain character and are generally not worth chasing unless you are a dedicated collector.
