Sayu vs Mizuki

Rolling healing ninja vs. Inazuma's refined Anemo support

TL;DR — Quick Pick

Pick Sayu if…

  • When you need a healer who can move quickly across the field
  • When you need a Claymore user for environmental puzzles
  • When you prefer the 'Sonic' style of play

Pick Mizuki if…

  • When you need more consistent Anemo application from a distance
  • When building a team that benefits from Catalyst-specific weapons (TTDS)
  • When you want a more traditional, stable Anemo support
Verdict

Mizuki offers more traditional and stable support as a Catalyst healer, while Sayu provides unique mobility. Mizuki is generally easier to slot into serious combat teams for VV shred and healing.

Strengths & Weaknesses

Sayu

Strengths
  • Strong Anemo damage
  • Versatile team options
Weaknesses
  • Requires investment
  • Best teams use limited 5-stars

Mizuki

Strengths
  • Extremely simple to play mechanically, all you need to do is float around.
  • Has healing built into her kit so no need to worry about sustain.
  • Offers a unique playstyle as the first dedicated Swirl DPS and on-field PHEC buffer.
Weaknesses
  • Very static playstyle; she spends her Skill duration floating around with nearly no player input needed.
  • Inability to use Normal Attacks in her Skill state means she can’t drive many of the best off-field PHEC damage dealers — significantly limiting both her teammate options and team damage ceiling.
  • Overall a poor Swirl trigger; her Anemo application is too limited to maximize her potential as a Swirl DPS.

Shared Team Members

With Sayu

Sayu can trigger Fischl's A4 passive frequently by Swirling Electro while in her Yoohoo Art: Fuuin Dash state. This combination creates a mobile Electro-swirl machine that deals consistent chip damage while Sayu maneuvers around the battlefield.

With Mizuki

Fischl provides the consistent off-field Electro application Mizuki needs to trigger Electro-Charged or Swirl reactions from range. Oz acts as a reliable battery and damage source, allowing Mizuki to focus on providing healing and Anemo utility to the team.
