Fu Xuan is a Quantum Element character that follows the Path of Preservation. Her primary role to the team is to mitigate her allies' DMG received through her Skill and Talent.
Her skill's effect called Matrix of Prescience mainly distributes the DMG received of her allies to herself, the percentage of DMG she can mitigate is also fixed. At the same time, her entire team receives an increase percentage of HP and Crit Rate. Whenever Fu Xuan's HP is at 50% and below, her Talent's 2nd passive will activate and then restores her HP. However, she must have at least 1 Trigger Count to activate it, this stack is only obtained from her ULT activation with a max stack of 2.

info
The only thing Fu Xuan needs is to have enormous amount of HP starting from 7000 and 1500 DEF to allow her longer DMG mitigation uptime. At the same time, having high Effect RES activates the Broken Keel's buff and prevents her from getting control debuffs. She might also need a speed stat starting from 135 so she can get faster turns.
Best Light Cones
SourceStellar Convergence, Light Cone Event Warp
Visioscape
Increases the wearer's Max HP by 24~40% and Energy Regeneration Rate by 12~20%. When the wearer's HP is reduced, all allies' DMG dealt increases by 9.0~15.0%, lasting for 2 turn(s).
At the start of every wave, restores HP to all allies by an amount equal to 80~100% of their respective lost HP.This lightcone gives her the best stat increase for durability and ULT uptime, DMG buffing enhancement whenever her HP is reduced, and HP restoration for all at the start of every wave.

Verdict
Increases the wearer's DEF by 24~40% and Effect Hit Rate by 24~40%. Increases the chance for the wearer to be attacked by enemies. When the wearer is attacked, increase their DEF by an extra 24~40% until the end of the wearer's turn.This greatly reduces the DMG she received from her DMG mitigation; however, she doesn't benefit from the EHR it provides because she doesn't cast any debuffs.
Treasure
Increases the wearer's Effect RES by 8~16%. If the wearer is attacked and has no Shield, they gain a Shield equal to 16~32% of their Max HP for 2 turn(s). This effect can only be triggered once every 3 turn(s). If the wearer has a Shield when attacked, the DMG they receive decreases by 12~24%.This is her Best F2P Lightcone that provides Effect Res, and Shield whenever she receives DMG. The shield also reduces the DMG she receives.
SourceStellar Warp, Departure Warp, Character Event Warp, Light Cone Event Warp
A New Round of Shuffling
Increases the wearer's DEF by 16~32%. When the wearer is attacked, there is a 100~120% base chance to Burn the enemy. For each turn, the wearer deals DoT that is equal to 40~80% of the wearer's DEF for 2 turn(s).This lightcone is good for Acheron teams as it inflicts Burn debuff whenever the wearer is targeted but Fu Xuan's mitigation effect cannot trigger it unless she receives a direct hit. Triggering the burn debuff gives1 additional stack for Acheron's ULT, allowing her faster ULT uptime.
SourceStellar Warp, Departure Warp, Character Event Warp, Light Cone Event Warp
Time Fleets Away

At This Very Moment
Increases the wearer's DEF by 16~24%. After entering battle, increases All-Type RES of all allies by 8~12%. Abilities of the same type cannot stack.This enhances her durability and grants DMG RES for the entire team at the start of the battle.
