Stellar Glimmer Reaction is the new elemental system Genshin Impact added with the Version 7.0 Snezhnaya update, and it has already changed how players build Cryo teams. If you jumped into Snezhnaya and got confused by a glowing icon you have never seen before, this guide breaks it down in plain terms: what triggers it, which characters make it work, and how to use it without wasting your resin on the wrong team.
TL;DR
- Stellar Glimmer is an umbrella term for two upgraded Cryo reactions: Stellar-Conduct and Stellar Swirl.
- Only a handful of characters can turn a normal reaction into a Stellar Glimmer reaction, including Odette, the Cryo Traveler, and Sandrone.
- Stellar-Conduct needs Cryo and Electro, while Stellar Swirl needs Cryo and Anemo.
- Triggering either reaction puts nearby party members into a Radiance state that boosts their damage or talents.
- Characters like Qiqi, Wriothesley, and Cyno get noticeably stronger once this system is active.
- You will run into this reaction naturally while exploring Snezhnaya, including during quests like the Pioneers quest.
What Is the Stellar Glimmer Reaction in Genshin Impact?
Stellar Glimmer is not a single reaction. It is a category that covers two enhanced versions of reactions you already know: Superconduct and Cryo Swirl. When certain characters are on your team, these two familiar reactions transform into their “Stellar” versions and do a lot more than the originals ever did.
Think of it the same way Dendro reactions changed how Genshin Impact played a few years back. Stellar Glimmer does something similar for Cryo, giving older Cryo and Electro characters a fresh reason to be in your party again. It arrived with the Genshin Impact 7.0 update, alongside the new Snezhnaya region and its local legends like Banje, Furiosa, and Churin.
How Does the Stellar Glimmer Reaction Work?
To trigger a Stellar Glimmer reaction, you need two things at the same time: the right elements colliding, and a character on your team who can convert that collision into its Stellar form. Without one of these “enabler” characters in your party, Cryo and Electro will just give you a normal Superconduct, and Cryo and Anemo will just give you a normal Swirl.
Stellar-Conduct: The Cryo and Electro Stellar Glimmer Reaction
Stellar-Conduct is the upgraded form of Superconduct. When Cryo meets Electro damage while an enabler character is active, it creates a field on the ground instead of a one-time burst. Party members standing inside this field get a boost to their Cryo and Electro damage, and enemies caught inside it take extra Physical damage on top of everything else. This makes Stellar-Conduct a strong pick if your team leans on both elements, since the field keeps working as long as you stay near it.
Stellar Swirl: The Cryo and Anemo Stellar Glimmer Reaction
Stellar Swirl is the upgraded version of a Cryo Swirl. Instead of a single hit of Anemo damage, it spawns a small cluster that first deals Anemo damage and then bursts into a wider area of Cryo damage. Both hits can land as critical hits. If you trigger Stellar Swirl again before the cluster explodes, it grows bigger and hits harder, so chaining it repeatedly is the best way to squeeze extra damage out of it before the final burst goes off.
Characters Who Can Trigger the Stellar Glimmer Reaction
As of the current version, only a few characters can act as the “key” that unlocks Stellar Glimmer reactions:
- Odette can trigger both Stellar-Conduct and Stellar Swirl. Her kit is built around this system, and her passive talent even scales her Stellar Glimmer damage with extra ATK, so gearing her right through her ascension and talent materials matters more than usual.
- The Cryo Traveler can also trigger both reactions, which makes the Traveler a genuinely useful support pick again for players who main this character.
- Sandrone can trigger Stellar-Conduct specifically, giving Electro-heavy teams another way to bring this reaction online.
Without at least one of these three in your party, you simply will not see the Stellar versions show up, no matter how much Cryo and Electro or Cryo and Anemo damage you stack.
Characters Who Benefit From the Stellar Glimmer Reaction
Once Stellar-Conduct or Stellar Swirl goes off, nearby allies enter a Radiance state. This state does not just add flat damage; it often boosts specific talents, so some characters benefit far more than others. A few standouts include:
- Qiqi, whose Stellar-Conduct focused build can lean on Radiance for a strong Attack boost at higher Constellations.
- Wriothesley, whose Cryo-focused kit lines up naturally with both Stellar reactions.
- Cyno, who brings reliable Electro application for Stellar-Conduct teams.
- Yae Miko, an off-field Electro applier that fits neatly into Stellar-Conduct comps without needing to be on-field often.
- Diona and Beidou, both of whom can help sustain or buff a Stellar Glimmer team while it cycles through its rotation.
- Layla, a budget-friendly Cryo applier who still contributes to keeping the reaction active.
Best Team Comps for the Stellar Glimmer Reaction
You do not need every five-star character mentioned above to make this system work. Here is a simple way to think about team building around it.
Stellar-Conduct Team Structure
Pick one enabler (Odette, Cryo Traveler, or Sandrone), pair them with a strong Electro applier like Cyno or Yae Miko, add a reliable Cryo support such as Qiqi or Layla, and round it out with a healer or shielder so your team can keep applying elements without dying to counterattacks in Snezhnaya’s tougher fights.
Stellar Swirl Team Structure
For Stellar Swirl, swap the Electro unit for a solid Anemo character. Keep an enabler on the field, a strong Cryo damage dealer for the follow-up burst, and support characters who can keep the cluster growing before you let it detonate.
Tips to Get the Most Out of the Stellar Glimmer Reaction
- Always check your team for an enabler first. If Odette, the Cryo Traveler, or Sandrone is not in the party, you are just getting normal Superconduct or Swirl.
- With Stellar Swirl, try to trigger it a few times in a row before letting the cluster burst, since the growing size means more damage per hit.
- Stand inside the Stellar-Conduct field rather than fighting at its edge, since the damage bonus only applies to characters standing in range.
- Prioritize ATK and Elemental Mastery on your enabler and main damage dealer, since both stats feed directly into how hard these reactions hit.
- Use downtime between big fights to clear Snezhnaya side content, like the Jack Frost quests or the local legends of Snezhnaya, while your new Cryo characters level up.
Where to Play Genshin Impact
If you want to try the Stellar Glimmer Reaction system for yourself, Genshin Impact is available across most major platforms. You can play on PC through the official Genshin Impact website, on mobile through the Google Play Store or the Apple App Store, or on console through the PlayStation Store and Xbox. PC players who prefer a launcher outside the official site can also grab it from the Epic Games Store.

You need one enabler character plus a source of Electro for Stellar-Conduct, or a source of Anemo for Stellar Swirl. The rest of the team can be flexible.
What is the Radiance state?
Radiance is the buff that party members receive after a Stellar-Conduct or Stellar Swirl reaction goes off. It usually enhances damage or specific talents for a short time.

Final Thoughts on the Stellar Glimmer Reaction
The Stellar Glimmer Reaction gives Genshin Impact’s Cryo characters a genuine reason to shine again, and it rewards players who already invested in Electro and Anemo units too. Start with whichever enabler you own, build around the supporting cast that fits your roster, and you will notice the damage difference the moment Stellar-Conduct or Stellar Swirl lights up on screen.
