Sayu vs Xianyun

The rolling ninja vs. the Adeptus of Cloud Retainer

TL;DR — Quick Pick

Pick Sayu if…

  • When you need a healer and VV shredder on a budget
  • When you enjoy horizontal travel and speed in the overworld
  • When you need a Claymore for ores

Pick Xianyun if…

  • When you want to enable Plunge Attack gameplay for any character
  • When you need superior teamwide healing and VV shred
  • When you have Furina (Xianyun is one of her best partners)
Verdict

Xianyun is a direct upgrade in terms of combat utility, offering unique plunge mechanics and better healing. Sayu remains a fun overworld explorer but cannot compete with Xianyun's specialized combat buffs.

Shared Team Members

With Sayu

Sayu's Burst provides periodic team-wide healing, but her slow application makes it difficult to fully maximize Furina's Fanfare stacks compared to dedicated healers. She can sustain the team, but the player must carefully time rotations to keep HP high enough for Furina's drain.

With Xianyun

Xianyun's high-volume team-wide healing instantly stacks Furina's Fanfare, providing a massive DMG buff to the entire team. Her Anemo element allows for VV shred while her Skill enables Furina to participate in high-damage Plunge Attack rotations.

With Sayu

Sayu acts as a budget Anemo battery and healer for Xiao, using her Burst to keep him healthy during his HP-draining Bane of All Evil state. While she provides basic utility, she lacks the specialized buffs that higher-tier Anemo supports offer for Xiao's specific playstyle.

With Xianyun

Xianyun is Xiao's best-in-slot support, providing massive Plunge DMG buffs that scale with her ATK and enabling his core mechanic without energy issues. Her team-wide healing effortlessly counters Xiao's self-drain and enables the use of Furina for even higher damage ceilings.
