Fu Xuan

Preservation sustain who redistributes damage and boosts allied HP and CRIT Rate

Released Sep 20, 2023

Fu Xuan spreads part of allies’ incoming damage to herself, reduces team damage, and raises allies’ Max HP and CRIT Rate while her Matrix of Prescience is active. Use her when you want the team’s incoming damage managed through one durable unit and can keep her Matrix active and Fu Xuan alive.

Fu Xuan GUIDE

Understand Fu Xuan

Useful when…

Reducing team damage and redistributing part of ally damage to Fu Xuan.
Increasing allies’ Max HP and CRIT Rate while Matrix of Prescience is active.
Using her Technique barrier to avoid combat entry from enemy attacks and start battle with Matrix active.

What does the Matrix do?

Her Skill activates Matrix of Prescience for three turns. While it is active, allies distribute 65% of damage they receive to Fu Xuan before that damage is mitigated by Shields. All allies also gain Max HP equal to 3% of Fu Xuan’s Max HP and 6% CRIT Rate. Her Talent separately reduces damage taken by all allies by 10% while Fu Xuan remains active in combat. If she is knocked down, the Matrix is dispelled.

How does her self-recovery work?

When Fu Xuan’s HP falls to 50% of Max HP or lower, she restores 80% of the HP she is currently missing. The effect begins with one trigger count and can hold up to two; her Ultimate grants one trigger count for this HP Restore effect. It cannot activate if the hit is a killing blow. Her Ultimate also deals Quantum damage to all enemies, and her Basic ATK scales with her Max HP.

What investments support her role?

The Skill governs the Matrix’s damage redistribution and team HP and CRIT benefits; the Talent governs both team damage reduction and Fu Xuan’s conditional recovery. Her HP bonus traces complement the HP-scaled Basic ATK and the Matrix’s HP increase. Her CRIT Rate traces are available if personal damage matters, but the central sustain function is in the Skill and Talent. Promotion raises her level and stats.

Where are the limits?

Damage redistribution shifts a substantial share of ally damage to Fu Xuan, so her own survival is central to keeping the Matrix in place. Self-recovery requires her to survive the triggering hit and be at or below half HP. The Technique barrier lasts 20 seconds, blocks enemy attacks, prevents the team from entering combat when attacked, and activates Matrix at battle start only if battle begins while the barrier is active.

Limitations and tradeoffs

Redistributed damage places a large share of ally damage on Fu Xuan.
Her Matrix ends if she is knocked down.
Her self-recovery cannot save her from a killing blow and depends on available trigger counts.

Common mistakes to avoid

Assuming redistributed damage is first reduced by Shields; the description places redistribution before shield mitigation.
Expecting Fu Xuan’s HP Restore to prevent a killing blow.
Letting the Technique barrier expire before battle and expecting its automatic Matrix activation.
