Fu Xuan is a 5-star Quantum Preservation (Tank/Support) in Honkai: Star Rail. Fu Xuan is the Master Diviner of the Xianzhou Luofu's Astrology Commission and one of the most self-sufficient sustain units in Honkai: Star Rail. She's on the Preservation path, combining HP-redistribution mechanics with team-wide damage reduction to keep her squad alive while still contributing to the fight. Her whole identity is built around proactive survivability: she doesn't just heal after the fact, she restructures how damage lands in the first place. That mix of tanking, damage mitigation, and Quantum presence gives her a utility profile that few sustain characters can match.
