Fu Xuan is one of the safest team-wide sustains, cutting damage for everyone and auto-saving allies from lethal hits. Roll if you keep dying in MoC; skip comfortably if you already own 
Aventurine or 
Huohuo.
Sub-stat priority: HP% > SPD > DEF% > Effect RES
Target SPD 134 (or at least 120 to trigger 
Fleet of the Ageless), 6000-8000 HP with Matrix active, and roughly 1400 DEF. No CRIT or EHR needed.

▾
Deals Quantum DMG equal to 70% of Fu Xuan's Max HP to one designated enemy.
▾
Activates Matrix of Prescience, via which Fu Xuan's teammates will Distribute 65% of the DMG they receive (before this DMG is mitigated by any Shields) to Fu Xuan for 3 turn(s). While affected by Matrix of Prescience, all ally targets gain the Knowledge effect, which increases their respective Max HP by 7.5% of Fu Xuan's Max HP, and increases CRIT Rate by 15%. When Fu Xuan is knocked down, the Matrix of Prescience will be dispelled.
▾
Deals Quantum DMG equal to 120% of Fu Xuan's Max HP to all enemies and obtains 1 trigger count for the HP Restore effect granted by Fu Xuan's Talent.
▾
While Fu Xuan is still active in combat, Misfortune Avoidance is applied to the entire team. With Misfortune Avoidance, allies take 22% less DMG. When Fu Xuan's current HP percentage falls to 50% of her Max HP or less, HP Restore will be triggered for Fu Xuan, restoring her HP by 95% of the amount of HP she is currently missing. This effect cannot be triggered if she receives a killing blow. This effect has 1 trigger count by default and can hold up to a maximum of 2 trigger counts.
▾
Attacks an enemy, and after entering combat, reduces their Toughness of the corresponding Type.
▾
After the Technique is used, all team members receive a Barrier, lasting for 20 seconds. This Barrier can block all enemy attacks, and the team will not enter combat when attacked. Entering battle while the Barrier is active will have Fu Xuan automatically activate Matrix of Prescience at the start of the battle, lasting for 2 turn(s).
When Matrix of Prescience is active, Fu Xuan will regenerate 20 extra Energy when she uses her Skill.
When Fu Xuan's Ultimate is used, heals all other allies by an amount equal to 5% of Fu Xuan's Max HP plus 133.
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 be triggered once. When "Matrix of Prescience" is activated again, the number of times this effect can be triggered will reset.

3★How to read this build page
Every character build page has these parts: recommended Light Cone/Relic sets and stat table, a Trace/skill leveling order, Eidolon milestones worth considering, and a reference SPD threshold. Read them in that order — gear tells you "what to use", Traces tell you "what to level first", Eidolon tells you "is it worth pulling dupes", SPD tells you "how fast you need to be to keep the rotation on time". The section below explains how to read each part and applies the same way to every character on the site — check the exact numbers in the table above this section, since community sources sometimes differ by a few points.
Why the Light Cone and Relic picks make sense
Most characters have a "signature" Light Cone built for their exact role, plus a few cheaper substitutes from the standard banner or easy-to-get 3-4★ cones. Missing the signature isn't a dead end — most characters keep most of their power with a well-matched substitute, typically losing somewhere between a few percent and roughly a fifth of total damage depending on the setup, per most public comparisons.
- Relic sets (2pc+2pc or 4pc) are picked for the set effect that fits that character's role (single-target DPS, AoE, shield/healing support, Break damage, and so on).
- Main stats per slot (Body/Feet/Sphere/Rope) and substats follow a priority that changes by role: DPS roles usually chase CRIT Rate/CRIT DMG before ATK%; Break-focused roles prioritize Break Effect; support/healing roles often value Effect Hit/RES or Outgoing Healing over pure CRIT.
These weights differ per character and can shift slightly between ranking sources — follow the exact priority table above rather than applying one formula to every role.
Trace/skill leveling order by role (a general guideline, not a fixed rule)
There's no single order that's correct for every character, and community sources sometimes disagree depending on the team the character is used in — but the general pattern by role is:
- DPS: level whichever skill (Skill or Ultimate) carries most of the damage for that character first, with Basic ATK usually last if it isn't the main damage source.
- Support/Buffer: prioritize Traces that boost buff strength or the skill that applies the effect over Basic ATK, since this role's value comes from lifting the team rather than personal damage.
- Healer/Shielder: prioritize the main healing or shield skill first, since that is the reason the team runs this character.
- Break/CC: prioritize whichever skill contributes the most Toughness Damage, since the Break/Weakness Break window is where the team dumps damage.
Major Traces unlock at fixed ascension levels in-game, not by choice — but which one to level first (when resources are limited) should follow the role priority above. Since the exact order can differ between ranking sources, check the specific recommendation in the table above for this character.
Eidolons: how far E0 gets you, and which milestone is worth considering
General rule: most characters at E0 (no duplicates) already handle most content, even 5-star characters. Eidolons are a duplicate-fueled upgrade system — higher levels cost more resources for a smaller power gain, and the actual gain varies a lot per character (some barely change role at E0, others shift how they're played at a specific level). The milestones most often cited by the community tend to sit at E1, E2, or E6 depending on the character — but none of these are required to clear the game's content. Check the Eidolon section in the table above for this character's specific milestone and gain; if sources disagree on how to rate a milestone, trust the in-game effect description over a pre-set percentage number.
How to think about SPD breakpoints
SPD (Speed) controls how often a character acts in the turn order — higher SPD means denser actions, and for some roles (especially support/healing that need to buff or heal before the team gets hit) hitting the right SPD "breakpoint" matters more than the raw SPD number. Values like 101 or 134 SPD are often cited as community-common breakpoints (letting a character act again before or after a specific point in certain team setups) — this is crowd-verified action-gauge math, not an official fixed number the game states for every situation. The right breakpoint also depends on the team and allies' SPD, so treat the SPD suggestion in the table above as a starting point to adjust from, not a mandatory target.
