Seven existing characters are getting reworked talents in the Luna VIII update, all tied to the new Stellar-Conduct reaction. The system handing out these upgrades is called Witch’s Revelation, and it touches Wriothesley, Yae Miko, Cyno, Qiqi, Diona, Beidou, and Yumemizuki Mizuki. Two of them also see their signature weapons buffed. The update lands on July 1, 2026.
Quick answer: Finish the world quest Revelations by Chance to obtain the Witch’s Revelation Case, then complete the Witch’s Revelation quest for each character you own who is at least Level 70. Once done, that character keeps an extra Additional Talent plus upgraded Constellations at C1, C2, C4, and C6.
How to unlock the Witch’s Revelation buffs
The buffs are not automatic. Each one is gated behind a short quest, and you only get the option for characters you actually own and have leveled high enough.
How the Stellar-Conduct reaction works
Every one of these buffs is built around Stellar-Conduct, a new reaction that fires when Cryo meets Electro under the right conditions. When it triggers, a Starlight Prism drops onto the field and forms a circular Polestar Field around it.
Inside that field, several things happen at once. Cryo and Electro damage both get a bonus for characters standing in the zone, the base reaction coefficient of Stellar-Conduct itself goes up, and the Physical RES of enemies caught inside is reduced. The field stores elemental energy on the battlefield and converts it into these party-wide buffs.
One important catch carries over from the Lunar reactions: not every character can set off Stellar-Conduct, and most of the new talents below only activate while a Polestar Field is present. In practice that means the field, and usually a character who can create it, is what switches these upgrades on.
Wriothesley buffs
Wriothesley becomes a strong on-field Stellar-Conduct option, with changes to his talents, Constellations, and his signature weapon Cashflow Supervision.
| Type | Effect |
|---|---|
| General | Enters the Radiance: Stellar-Conduct state inside a Polestar Field. Part of his enhanced Charged Attacks and enhanced Normal Attacks (during his Skill state) counts as Stellar-Conduct DMG, and he gains a Stellar-Conduct DMG bonus. |
| General | Enhanced Charged Attacks lose their cooldown completely and restore HP on hit, limited to once every two seconds. |
| Constellation | Raises Stellar-Conduct DMG, adds bonus Cryo DMG that counts as a Stellar-Conduct reaction, reduces damage he takes, grants party-wide ATK SPD, boosts CRIT Rate and CRIT DMG with extra icicle DMG, and increases his enhanced Normal and Charged Attack damage. |
| Signature weapon | Cashflow Supervision: when current HP rises or falls, Stellar-Conduct DMG increases by 14%. |
Yae Miko buffs
Yae Miko’s rework directly fixes her long-standing weakness: her Sesshou Sakura no longer vanish when she casts her Burst. Her signature catalyst Kagura’s Verity is upgraded too.
| Type | Effect |
|---|---|
| General | Enters Radiance: Stellar-Conduct inside a Polestar Field, where part of her damage counts as Stellar-Conduct reaction DMG, and she gains a damage bonus plus extra lightning strike damage. |
| General | Total Sesshou Sakura duration increases by 10 seconds, and existing totems are no longer destroyed when she casts her Elemental Burst. With 3 Sesshou Sakura active, casting her Skill triggers an extra lightning strike. |
| Constellation | Raises Elemental Mastery for her and the party, restores extra Elemental Energy, adds an Elemental Burst DMG bonus, grants teammates an Electro and Stellar-Conduct DMG bonus, and greatly increases her Stellar-Conduct reaction CRIT DMG. |
| Signature weapon | Kagura’s Verity: the Kagura Dance effect also raises Stellar-Conduct DMG by 12%. |
Cyno buffs
| Type | Effect |
|---|---|
| General | Enters Radiance: Stellar-Conduct inside a Polestar Field. When he triggers Judication in this state, Duststalker Bolts deal Stellar-Conduct DMG. |
| General | His Elemental Skill can be infused at any time, and he can briefly enter the Pactsworn Pathclearer state to deal Electro DMG regardless of timing. |
| Constellation | While in Pactsworn Pathclearer, raises Elemental Mastery for Cyno or the party, increases his Stellar-Conduct DMG, and restores his Elemental Energy. |
Qiqi buffs
| Type | Effect |
|---|---|
| General | Enters Radiance: Stellar-Conduct inside a Polestar Field, boosting Superconduct and Stellar-Conduct DMG for the whole party. Her Elemental Burst can deal extra Stellar-Conduct DMG. |
| General | Herald of Frost Skill cooldown drops to 15 seconds, and whenever the on-field character lands a hit, Herald of Frost fires its own coordinated Cryo attack. |
| Constellation | Restores extra HP, restores Elemental Energy, raises ATK, and increases the on-field character’s Stellar-Conduct DMG while in the Stellar-Conduct state. |
Diona buffs
| Type | Effect |
|---|---|
| General | Enters Radiance: Stellar-Conduct inside a Polestar Field. For a short time after using her Elemental Skill, she fires Icy Paws whenever party members trigger Superconduct or Stellar-Conduct. |
| Constellation | Raises her Max HP, and while in Radiance: Stellar-Conduct, characters inside her Burst field deal increased Superconduct and Stellar-Conduct DMG. |
Beidou buffs
| Type | Effect |
|---|---|
| General | Enters Radiance: Stellar-Conduct inside a Polestar Field. Holding her Elemental Skill stores power, and the more she stores, the more her Skill cooldown is reduced and Elemental Energy is restored. |
| Constellation | While in Radiance: Stellar-Conduct during her Elemental Burst, she lowers nearby enemies’ Cryo RES and raises the on-field character’s Elemental Mastery. |
Yumemizuki Mizuki buffs
Mizuki’s upgrade leans on her Anemo and Swirl identity rather than a Cryo-Electro core, so her changes center on the Dreamdrifter state.
| Type | Effect |
|---|---|
| General | While in Dreamdrifter, triggering a Swirl reaction increases her next instance of AoE Anemo DMG and raises the party’s Elemental Mastery. |
| Constellation | While in Dreamdrifter, she deals extra Anemo DMG, reduces enemies’ Pyro, Hydro, Cryo, Electro, and Dendro RES, restores additional HP, and raises CRIT Rate and CRIT DMG. |
Because almost every general buff above keys off the Polestar Field, these characters lean heavily on having a Stellar-Conduct enabler in the team to reach their full output. If you already own Yae Miko, Wriothesley, or any of the others on this list, the Witch’s Revelation quests are worth running as soon as you have the Witch’s Revelation Case in hand and your character at Level 70.
