Stellar-Swirl is a Version 7.0 reaction that only fires when a character carrying a Stellar Linchpin is in your party: instead of a normal Swirl, Cryo mixing with Anemo drops a Stellar Vortex on the enemy that detonates for Cryo damage after a short delay, and re-triggering the reaction before that detonation levels the vortex up instead of wasting the hit. It sits under an umbrella HoYoverse calls Stellar Glimmer, and it’s the reason team-building in Snezhnaya suddenly looks different from every previous Cryo comp.
Version 7.0 introduces Stellar Glimmer, a new reaction system built around Cryo and specific Snezhnaya characters, changing existing Cryo interactions into Stellar-Conduct and Stellar Swirl when a Stellar Linchpin character is in the party. Players cannot simply combine the correct elements and expect it to activate — the party must first meet its character requirements. That single sentence is why two players running what looks like the same rotation get different numbers: one has the enabling character, the other doesn’t.
TL;DR
- Stellar-Swirl replaces normal Swirl only when a Stellar Linchpin character is in the party
- It spawns a Stellar Vortex that explodes after a delay for Cryo damage instead of hitting instantly
- Triggering it again before the vortex detonates levels the vortex up rather than starting a new one
- Sandrone, Odette, and the Cryo Traveler are the confirmed enablers as of 7.0
- Exact damage multipliers and the vortex’s detonation timer are not officially published yet
| Reaction | Elements | What it replaces | What it does |
|---|---|---|---|
| Stellar-Swirl | Anemo + Cryo | Standard Swirl | Uses Anemo and Cryo with Stellar Glimmer characters to trigger an enhanced Snezhnayan variant of Swirl, spawning a vortex that explodes for Cryo damage |
| Stellar-Conduct | Cryo + Electro | Superconduct | Occurs between Cryo and Electro when a Stellar Glimmer character is present in the party, creating a field that shreds Physical RES and buffs the team |
How Stellar-Swirl Actually Triggers: The Conditions That Matter
Stellar Linchpin is a special type of Vision carried by characters from Snezhnaya, and it’s the actual gatekeeper here — not the element, the character. Stellar-Conduct can only be triggered when the party has a character that enables the reaction by existing, like Sandrone, Odette, and the Cryo Traveler, and the same three names cover Stellar-Swirl too. Players unlock the system after interacting with the Statue of the Seven in Snezhnaya and activating it through the Cryo Traveler, which matters because the Cryo Traveler is completely free from the Snezhnayan Statue of the Seven, so even F2P players can access this team immediately. Anyone chasing the fastest way to unlock stellar swirl without pulling a banner character should start there.
Tip
The instinct from every other reaction is fire-and-forget. Here that habit costs damage — check the section below before you assume faster rotations are automatically better.
| Condition | What happens | If the condition is NOT met |
|---|---|---|
| Stellar Linchpin character in party (Sandrone, Odette, or Cryo Traveler) | The reaction replaces its conventional counterpart rather than triggering alongside it — Cryo+Anemo becomes Stellar-Swirl | Cryo interacts with Electro and Anemo using the standard elemental reactions — you get plain old Swirl, no vortex, no crit |
| Anemo application present on a Cryo target | Spawns a Stellar Vortex at the enemy's position that will detonate later | No vortex forms; nothing to level, nothing to detonate |
| Repeated Stellar-Swirl triggers before the vortex explodes | The vortex's explosion can be triggered with repeated triggers of Stellar-Swirl within its vicinity, leveling it up | Vortex sits at its base level and detonates for its smallest hit |
Step-by-Step: How to Stack and Detonate a Stellar Vortex
Follow this sequence to get it done fast.
-
1
Slot a Stellar Linchpin character
bring Sandrone, Odette, or the Cryo Traveler, since without one of the three you never get Stellar-Swirl at all.
-
2
Apply Cryo to the target
either through the Linchpin's own kit or a teammate, so there's an aura to Swirl.
-
3
Hit it with Anemo
this is the moment a Stellar Vortex spawns at the enemy's location instead of a normal Swirl.
-
4
Re-trigger before it pops
apply the Anemo/Cryo combo again while the vortex is still active to push it up a level rather than wasting the window.
-
5
Let it detonate
the vortex sits on the field for several seconds and then detonates, dealing AoE Cryo damage at whatever level you built it to.
-
6
Watch the 8-second direct damage window
direct Stellar-Swirl DMG can be dealt for 8s after triggering a Stellar-Swirl reaction, so kit effects tied to that damage type only count inside that timer.
How This Changes Team Building: Anemo Is No Longer Just Support
Anemo units used to be pure enablers — apply the Swirl, buff resistance shred, step off-field. Stellar-Swirl changes the math because the Anemo hit is now the trigger for something that scales and detonates later. Sucrose becomes important since she’s the second part of any Swirl reaction the team produces, and beyond just triggering, she reduces enemies’ resistance to both Cryo and Electro while also raising the team’s Elemental Mastery to further enhance every Stellar reaction. That’s an Anemo unit contributing to a damage number directly, not just enabling someone else’s number. It’s also why the two Stellar reactions aren’t mutually exclusive: Stellar-Conduct and Stellar Swirl can entirely co-exist, and you’re able to trigger both with a Cryo/Electro/Anemo mix, though Radiance: Stellar-Conduct will take priority over Radiance: Stellar Swirl for characters that can deal both. Readers already deep into region content should also check what to prioritise in Genshin Impact 7.0 Snezhnaya: What to Do First, since the Statue of the Seven unlock for Stellar reactions sits inside that same early-region checklist.
For general roster planning beyond this one reaction, the Genshin Impact Artifact Guide 2026 covers the crit and Elemental Mastery sets these Stellar-Swirl teams actually want on their carries.
| Method | Role fit | Effort | Best for |
|---|---|---|---|
| Cryo Traveler + Sucrose core | F2P enabler, no pulls needed | Low | New or free-to-play accounts testing the reaction |
| Odette off-field + on-field Stellar DPS | Off-field sub-DPS scaling off ATK and EM whose skill delivers periodic AoE Cryo hits while buffing the team's Stellar Glimmer reactions | Medium | Players building around a dedicated Stellar carry |
| Sandrone-driven Stellar-Conduct/Swirl hybrid | Needs a team of Electro and Cryo characters to trigger as many Stellar-Conduct reactions as possible | High | Established Sandrone owners chasing max reaction uptime |
| Mizuki + Odette or Cryo Traveler | Mizuki does not enable Stellar Swirl reactions herself, so she needs either Odette or the Cryo Traveler to enable it | Medium | Elemental Mastery/crit hybrid on-field DPS teams |
What Stellar-Swirl Rewards You With
Why the crit part is the actual headline
Standard Swirl is a transformative reaction that deals Anemo-infused elemental damage but cannot crit. Stellar-Swirl breaking that rule is the part that reshapes gear priorities, since it means a reaction can now benefit from CRIT Rate and CRIT DMG substats the same way a normal attack does, alongside Elemental Mastery.
Vortex leveling is the real skill expression
Instead of one clean number, the reward scales with how disciplined your rotation is. The key mechanic is Vortex leveling — the reaction rewards patience over speed, which is the opposite of how every other transformative reaction in the game has worked since launch.
| Reward | How you get it | Why it matters |
|---|---|---|
| Vortex Cryo detonation | Trigger Anemo into Cryo (or vice versa) with a Linchpin in party | Delayed AoE Cryo hit instead of an instant, weaker Swirl tick |
| Crit-capable reaction damage | Vortex leveling through repeated triggers before detonation | Stellar Swirl can critically hit, making it one of the most damage-dense reactions in the game when played correctly |
| Direct Stellar-Swirl DMG window | Certain kit effects that key off the reaction | Lasts for 8s after triggering the reaction, a hard timing constraint for rotation planning |
Stellar-Conduct and the Numbers Nobody Has Confirmed Yet
Stellar-Conduct: the other reaction in the family
Stellar-Conduct is the Cryo/Electro sibling reaction, and it actually predates Stellar-Swirl: it came out alongside Sandrone and the Witch’s Revelation buffs in Patch 6.7. When it triggers, the surrounding area turns into a Polestar Field where characters receive a Cryo and Electro DMG bonus, and the field also shreds Physical Resistance of enemies. The field records Cryo or Electro hits on the enemy as stacks, and the more stacks stored, the greater the buffs. That’s the confirmed shape of it. What isn’t confirmed, at least not from anything official this early into 7.0, is the exact stack cap, the per-stack buff value, or how those numbers interact with specific character kits beyond the broad strokes fan sites have datamined.
What we still don’t know
- The exact detonation timer for the Stellar Vortex, beyond “a short delay after the reaction”
- The precise damage multiplier per vortex level, or the hard cap on how many times it can level
- The full damage coefficients behind Direct Stellar DMG — a general formula shape has circulated, but the actual numbers inside it aren’t officially published
- Whether more Snezhnaya characters beyond Sandrone, Odette, and the Cryo Traveler will carry a Stellar Linchpin in future patches
Warning
The mechanic is only days old at the time of writing. Treat any tier list or “best team” ranking you see right now as an early guess, not a settled meta call — the underlying multipliers haven’t been laid out officially yet.
Common Misconceptions About Stellar-Swirl
Myth: any Anemo character instantly gives you Stellar-Swirl
No. The Anemo half is just one ingredient. Only teams containing a Stellar Linchpin character can activate Stellar-Conduct or Stellar Swirl; without one, Cryo interacts with Electro and Anemo using the standard elemental reactions. Bring Sucrose without Sandrone, Odette, or the Cryo Traveler and you’re still just Swirling normally.
Myth: spamming the reaction as fast as possible is optimal
This is the habit that breaks under the new rule. Since the vortex’s explosion can be triggered with repeated triggers of Stellar-Swirl within its vicinity and that re-triggering is what levels it up, rushing to detonate the instant it appears skips the entire point of the mechanic. The reaction rewards holding it, not clearing it fast.
Myth: Stellar-Swirl and Stellar-Conduct are the same thing
They share a family name and overlapping enablers, but they’re built on different element pairs and different payoffs — one is a delayed Cryo vortex with crit potential, the other is a stacking field that buffs Cryo and Electro DMG over time. Stellar-Conduct and Stellar Swirl can entirely co-exist as reactions, which is exactly why confusing them leads to misreading damage logs.
Our Take: Is Stellar-Swirl Worth Building Around
Our Take
Worth learning the rule now, too early to rank the teams.
The mechanic itself is a genuine departure — a transformative reaction that crits and rewards holding your trigger instead of spamming it hasn’t existed in this game before, and that alone makes it worth understanding rather than skipping. But the exact numbers behind vortex levels and Polestar stacks aren’t public yet, and anyone telling you a definitive best team three days into a patch is guessing with confidence, not reporting a settled meta. If you already own Sandrone, Odette, or built Cryo Traveler artifacts, testing the rotation costs nothing. If you don’t, there’s no rush — the Statue of the Seven unlock and the Cryo Traveler enabler aren’t going anywhere.
For where this reaction actually gets tested under pressure, the Genshin Impact Endgame Guide: Spiral Abyss vs Imaginarium Theater is a reasonable next stop once a Stellar team is built.
