Genshin Impact 6.7 Mizuki Buffs - Stellar Superconduct Kit Leaks
Yumemizuki Mizuki is set to be part of the next round of older character adjustments rolling out alongside Sandrone and the new Stellar Superconduct reaction in Genshin Impact 6.7. Unlike the Cryo and Electro units in the same batch, Mizuki stays an Anemo Swirl enabler, but her kit picks up stronger damage scaling, a small party-wide Elemental Mastery share, and a meaningful resistance shred tucked into her constellations.
⚠️
All numbers below come from pre-release leaks tied to the 6.7 beta cycle. Values can shift before the patch ships, and nothing here is officially confirmed by HoYoverse.
Quick answer: Mizuki's Skill state now grants a 1000% EM scaling buff to her Anemo attacks on Swirl trigger and shares 10% of her EM with the party, while C2 adds a 20% resistance shred to Pyro, Hydro, Cryo, Electro, and Anemo.

Where Mizuki fits in the 6.7 buff wave
Patch 6.7 introduces Stellar Superconduct, a Cryo and Electro reaction tied to Sandrone's debut. The reaction creates a field, sometimes referenced as the Stellar Glow Domain, where Cryo and Electro hits grant short DMG bonuses, the base Stellar Superconduct multipliers go up, and enemies inside take reduced Physical RES.
The character adjustments arriving with it cover Yae Miko, Wriothesley, Cyno, Diona, Qiqi, Beidou, and Mizuki. Every unit in that list except Mizuki gains access to a new Radiant state inside the Stellar Superconduct field. Mizuki keeps her Anemo identity and instead receives a straight Swirl-focused upgrade that does not depend on the new reaction to function.
Mizuki's new passive and Skill behavior
The headline change is on her first passive. While she is in the Dreamdrifter state from her Elemental Skill, Swirl triggers no longer extend the duration. Instead, each Swirl increases the damage of her Anemo attacks by 1000% of her Elemental Mastery. On top of that, Mizuki passively shares 10% of her own EM with the rest of the party while the Skill state is active.
That second part is the more quietly important change. It turns Mizuki into a mild EM battery for teammates who care about reaction damage, which lines up with how she is usually played as an on-field Swirl driver in Electro-Charged, Overloaded, and Frozen comps.

Constellation changes
Most of the heavier numbers sit in her constellations. C1 reworks her existing debuff to be cleared on Swirl damage rather than expiring on its own, with a bigger payoff when it triggers. C2 stays the most impactful upgrade for team building, and C6 finally gives her crit value scaled off Elemental Mastery.
| Constellation | Updated effect |
|---|---|
| C1 | The C1 mark on enemies is removed when they take Swirl damage. That Swirl instance deals additional damage equal to 1100% of Mizuki's EM, and enemies take an extra hit of Anemo damage equal to 1000% of her EM. |
| C2 | While Mizuki is in Skill state, enemies take 20% more Pyro, Cryo, Electro, Hydro, and Anemo damage. |
| C4 | The orbs created during her Elemental Burst gain an extra healing effect that targets the ally with the lowest HP. |
| C6 | Mizuki gains up to 20% Crit Rate and 80% Crit DMG, scaling from her Elemental Mastery. |
The C2 resistance shred is the standout. A flat 20% reduction across five elements stacks with Viridescent Venerer's 40% elemental RES shred on the Swirled element, and it covers Anemo damage on top, which VV does not.
What this means for her teams
Mizuki's existing role as a Swirl on-fielder does not change. She still wants Elemental Mastery on every artifact slot, still pairs best with off-field Hydro, Electro, Pyro, or Cryo enablers, and still benefits from Viridescent Venerer as her main 4-piece set. The buffs mostly raise her personal damage ceiling and make her support contribution stronger without changing rotations.
Players running her with characters like Furina, Fischl, Ororon, Xiangling, Raiden Shogun, or Citlali will see the largest gains, since those teammates already scale with reactions and benefit from the shared EM and added resistance shred. The leaked Stellar Swirl interaction, if it ends up reading her Swirl damage as a valid source, would extend her usefulness into Stellar Superconduct comps as well, but that pathway is still unconfirmed.

Limitations to keep in mind
The buffs do not address Mizuki's biggest awkward interaction. Because she attacks automatically during Dreamdrifter, she still cannot trigger the coordinated attacks on units like Xingqiu, Yelan, or Beidou, so those characters remain weaker partners for her than for a more traditional on-field DPS.
The C6 crit conversion also caps fairly low at 20% Crit Rate and 80% Crit DMG, and applies to Mizuki herself rather than party-wide Swirl damage. Swirl reactions still cannot crit on their own without something like her own constellation-based effects in play, so the C6 mostly helps her direct Anemo hits rather than transforming reaction output.
Release context
Version 6.7 is the patch tied to Sandrone's debut as a 5-star Cryo Claymore user and the introduction of Stellar Superconduct as a new reaction. No official next release date for 6.7 has been confirmed by HoYoverse, and the buff details above are still subject to beta adjustments. Expect the final numbers to be locked in closer to the version's official livestream and patch notes.
