Kazuha vs Mizuki

The undisputed support king vs. Inazuma's versatile helper

TL;DR — Quick Pick

Pick Kazuha if…

  • When you want to maximize your Main DPS's elemental damage
  • If you need strong grouping to clear waves quickly
  • For high-end competitive Abyss clears

Pick Mizuki if…

  • If you need an Anemo support who can also heal the team
  • When you want to use Thrilling Tales of Dragon Slayers for ATK buffs
  • If you prefer a simpler, more defensive Anemo slot
Verdict

Kazuha is the clear choice for offensive ceiling and grouping power. Mizuki provides a more comfortable, role-compressed option by adding healing and Catalyst utility to the Anemo support slot.

Strengths & Weaknesses

Kazuha

Strengths
  • A4 passive gives the entire team massive Elemental DMG Bonus — universal buff for every elemental DPS
  • Viridescent Venerer 40% RES shred layers on top of A4 buff
  • Excellent grouping from Skill's Plunge and Burst AoE
Weaknesses
  • Provides little to no benefit for Geo or Physical DPS teams
  • Plunge Skill can send lightweight enemies flying out of range
  • Building him requires EM-heavy artifacts — limited CRIT synergy

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 Kazuha

Kazuha is essential for Neuvillette as he provides both a massive Hydro DMG buff and Viridescent Venerer resistance shred. His grouping capability is vital for lining up enemies so that Neuvillette's Charged Attack beam can hit as many targets as possible. Kazuha also easily triggers one of Neuvillette's Draconic Glories stacks through a Hydro Swirl reaction.

With Mizuki

Mizuki provides the team with consistent healing and Hydro shred, which are key for sustaining Neuvillette and increasing his personal damage. By occupying the Anemo slot, she allows for Viridescent Venerer application while freeing up other slots for defensive or reactive supports. Her grouping abilities help Neuvillette maintain focus on high-priority targets during his Hydro Pump state.

With Kazuha

Kazuha can perform a 'Double Swirl' to shred both Hydro and Pyro resistance, significantly boosting Xiangling's Pyronado damage in Vape teams. His Elemental Burst can be infused with Pyro to provide additional application, ensuring that Hydro units like Childe or Ayato can consistently vaporize. The grouping he provides also ensures Pyronado hits all enemies in a cluster.

With Mizuki

Mizuki provides the necessary Viridescent Venerer shred to maximize Xiangling's Pyro damage while offering healing to keep the team alive. She can use her grouping skills to pull enemies into the path of the rotating Pyronado, increasing its effective hit count. Additionally, her presence allows for Anemo resonance if another Anemo unit is used, reducing cooldowns and stamina consumption.
