The Luna VIII update rewires seven existing Genshin Impact characters around a brand-new elemental reaction called Stellar-Conduct. The upgrades come through a system named Witch’s Revelation, which hands each eligible character an Additional Talent plus reworked Constellations at levels 1, 2, 4, and 6. Wriothesley, Yae Miko, Cyno, Qiqi, Diona, Beidou, and Yumemizuki Mizuki are the ones affected, and the update went live on July 1, 2026.
Quick answer: Own the character at Level 70 or higher, complete the world quest Revelations by Chance to obtain the Witch’s Revelation Case, then finish that character’s Witch’s Revelation quest to permanently apply the new talent and Constellation buffs.
Requirements to unlock a Witch’s Revelation buff
The buffs are not automatic. You have to own the specific character and clear a short quest chain before anything changes. Two conditions gate the process.
Once the case is in your inventory, each eligible character offers their own Witch’s Revelation quest. Finishing it grants the Additional Talent and the Constellation enhancements at once. The quests are fully voice-acted and do not take long to clear.
If you do not own the five-star characters on the list, you can pull them and their signature weapons from the limited Heavenlit Prophecy banner, also called the Lightrace Wish. Keep in mind that the wish guarantee count is shared with the Chronicled Wish, so pity carries between the two.
How Stellar-Conduct and the Polestar Field work
Every buff ties into Stellar-Conduct, which triggers when Cryo makes contact with Electro. When that happens, a Starlight Prism appears and creates a circular Polestar Field on the battlefield. That field is where most of the reworked kits actually come alive.
Inside the Polestar Field, the party gains a Cryo and Electro DMG bonus, the base reaction coefficient of Stellar-Conduct goes up, and enemies inside the field have their Physical RES reduced. Six of the seven characters enter a special Radiance: Stellar-Conduct state while standing in the field, which unlocks their extra effects. Note that, like Lunar reactions, not every character can trigger Stellar-Conduct.
What each character gains
The seven upgrades split roughly into damage dealers who now output Stellar-Conduct damage and supports who feed the reaction for the team. Here is the role each character takes after the rework.
| Character | Rarity / Element | New role after buff |
|---|---|---|
| Wriothesley | 5★ Cryo | On-field DPS with a full Stellar-Conduct attack playbook |
| Yae Miko | 5★ Electro | Off-field Electro enabler and team buffer |
| Cyno | 5★ Electro | DPS with Stellar-Conduct-infused enhanced skills |
| Qiqi | 5★ Cryo | Off-field support boosting party reaction damage |
| Yumemizuki Mizuki | 5★ Anemo | Swirl buffer and Elemental Mastery support |
| Diona | 4★ Cryo | Cryo applier with party-wide reaction support |
| Beidou | 4★ Electro | Energy battery with Cryo RES shred at C6 |
Wriothesley
Inside a Polestar Field, Wriothesley enters the Radiance: Stellar-Conduct state, and part of the damage from his enhanced Normal and Charged Attacks counts as Stellar-Conduct DMG, plus he gains a Stellar-Conduct DMG bonus. His enhanced Charged Attacks lose their cooldown entirely and restore HP on hit, capped at once every two seconds. Constellations layer on more Stellar-Conduct and bonus Cryo damage, damage reduction, party-wide ATK SPD, and CRIT boosts with extra icicle hits. His signature weapon, Cashflow Supervision, adds a further 14% Stellar-Conduct DMG whenever his current HP changes.
Yae Miko
Yae Miko keeps her off-field role but now supports allies as well. Her total Sesshou Sakura duration increases by 10 seconds, and existing totems are no longer destroyed when she casts her Elemental Burst. With three Sesshou Sakura on the field, casting her Elemental Skill triggers an additional lightning strike. Her Constellations raise Elemental Mastery for the team, restore energy, add Burst DMG, and grant teammates an Electro and Stellar-Conduct DMG bonus while sharply increasing her Stellar-Conduct reaction CRIT DMG. Her signature Kagura’s Verity now adds 12% Stellar-Conduct DMG through the Kagura Dance effect.
Cyno
Cyno enters the Radiance: Stellar-Conduct state in a Polestar Field, and when he triggers Judication there, his Duststalker Bolts count as Stellar-Conduct DMG. His Elemental Skill can now be infused at any time, and he can briefly enter the Pactsworn Pathclearer state to deal Electro DMG regardless of timing. His Constellations raise Elemental Mastery in the Pactsworn Pathclearer state, boost his Stellar-Conduct DMG, and restore his energy.
Qiqi
Qiqi becomes a genuine reaction support. In the Polestar Field she boosts Superconduct and Stellar-Conduct DMG for the whole party, and her Elemental Burst can deal an extra hit of Stellar-Conduct DMG. Her Herald of Frost skill cooldown drops to 15 seconds, and the Herald now launches a coordinated Cryo attack whenever the on-field character lands a hit. Her Constellations add extra healing, energy restoration, an ATK boost, and more Stellar-Conduct DMG for the active character.
Yumemizuki Mizuki
Mizuki is the odd one out as an Anemo unit, and she does not enter the Radiance state. Instead, while in her Dreamdrifter state, triggering a Swirl reaction increases her next AoE Anemo DMG and raises the party’s Elemental Mastery. Her Constellations add more Anemo DMG in Dreamdrifter, reduce Pyro, Hydro, Cryo, Electro, and Dendro RES on enemies, restore HP, and grant CRIT Rate and CRIT DMG.
Diona
Diona enters the Radiance: Stellar-Conduct state inside a Polestar Field. For a set window after her Elemental Skill, she fires Icy Paws whenever party members trigger Superconduct or Stellar-Conduct, which keeps Cryo application steady for the reaction. Her Constellations increase her Max HP and, in the Radiance state, make characters inside her Elemental Burst field deal more Superconduct and Stellar-Conduct DMG.
Beidou
Beidou shifts toward a battery role. Holding her Elemental Skill accumulates power, and the more she stores, the more her skill cooldown drops and the more energy she restores. She also enters the Radiance: Stellar-Conduct state in a Polestar Field. At C6, her Elemental Burst lowers the Cryo RES of nearby enemies and raises the on-field character’s Elemental Mastery.
How to confirm the buff is active
Once you finish a character’s Witch’s Revelation quest, the new Additional Talent appears in that character’s talent screen, and the reworked descriptions replace the old Constellation text. If the changes are not showing, the usual cause is a missed requirement. The character is below Level 70, you have not obtained the Witch’s Revelation Case from Revelations by Chance, or you have not completed that specific character’s quest yet.
With the buffs applied, older units that had drifted out of the meta gain a concrete reason to return. Cyno and Wriothesley pick up Stellar-Conduct damage that lets them slot into Cryo and Electro comps, while Qiqi and Diona turn into low-effort reaction supports as the game heads toward Snezhnaya, the home of ice.
