- Stellar Glimmer damage formula: Base Reaction Damage × (1 + EM Bonus + Stellar Glimmer Bonus) × Level Multiplier
- Two variants: Stellar Swirl spreads to nearby enemies; Stellar-Conduct stacks on a single target
- Trigger order matters: the enemy must carry a Cryo aura or be Frozen before the Stellar source hits
- Level scaling dominates early game; Elemental Mastery and dedicated bonuses define the late-game ceiling
- Target 80%+ reaction uptime by alternating Cryo and Stellar applications every 2–3 seconds
The Stellar Glimmer Damage Formula Explained
The Stellar Glimmer damage formula is the core calculation behind Genshin Impact 7.0's flagship Snezhnaya reaction. Every instance of damage follows this structure:
Reaction Damage = Base Reaction Damage × (1 + Elemental Mastery Bonus + Stellar Glimmer Bonus) × Level Multiplier
Each variable in the formula weights differently depending on your progression stage:
| Formula Variable | What It Represents | When It Matters Most |
|---|---|---|
| Base Reaction Damage | Flat reaction base value | All stages, scales with character level |
| Elemental Mastery Bonus | EM-derived multiplier | Mid to late game builds |
| Stellar Glimmer Bonus | Dedicated reaction bonus stats | Late game ceiling, artifact/set sources |
| Level Multiplier | Character level scaling | Dominant factor in early game |
The reaction triggers only when a Cryo aura (or a Frozen state) is already on the enemy before the Stellar-aligned application lands. If the Stellar source hits first, it only applies aura without triggering the reaction — making application order the single most common damage loss players encounter.
Reversing the application order does not trigger Stellar Glimmer. Always apply Cryo or Freeze first, then hit with your Stellar source to actually fire the reaction.
Stellar Swirl vs Stellar-Conduct Damage Differences
The two variants of the reaction use the same base formula but distribute damage differently. Choosing the wrong variant for the content is the fastest way to lose total damage output.
| Variant | Damage Distribution | Best Use Case | Multiplier Profile |
|---|---|---|---|
| Stellar Swirl | Spreads mark to nearby enemies | AoE content, grouped waves | Lower per-target multiplier |
| Stellar-Conduct | Focuses full reaction on one target | Bosses, elite single-target | Stacking bonus for consecutive triggers |
Stellar-Conduct rewards consecutive triggers on the same enemy with a stacking damage bonus, which is why sustained single-target rotations — like the Traveler (Cryo) boss-killer loop — extract far more value than scattered applications. Stellar Swirl instead trades per-target damage for coverage, making it the default pick whenever three or more enemies are grouped.
Stellar Swirl Setup
- Group enemies first with Anemo crowd control
- Maintain Cryo aura across the pack
- Trigger once and let the mark spread
- Best with Ganyu burst coverage
Stellar-Conduct Setup
- Freeze-lock a single elite or boss
- Trigger repeatedly on the same target
- Stack the consecutive-trigger bonus
- Best with Traveler (Cryo) and Ayaka
A practical rule: one to two enemies favors Stellar-Conduct stacking; three or more favors Stellar Swirl spreads. Re-check the encounter before committing your rotation.
Frozen and Shatter Interaction With the Formula
Hitting a Frozen enemy with Stellar Glimmer modifies the damage outcome in two ways: it extends the freeze window, and it converts part of the reaction damage into a bonus Shatter instance when the freeze breaks.
| Interaction | Effect on Damage | Team Benefit |
|---|---|---|
| Cryo aura only | Standard formula result | Baseline reaction damage |
| Frozen enemy | Extended freeze window | More time for stacking triggers |
| Freeze breaks after trigger | Partial conversion to bonus Shatter | Extra damage instance |
This is why teams that stack Cryo application before triggering — such as the double Cryo Freeze core with Ayato maintaining Hydro — consistently outperform teams that trigger on a bare aura. The Shatter conversion component effectively gives you a second, free damage instance on top of the base formula output.
Treat Freeze as part of your damage calculation, not just crowd control. The extended window plus bonus Shatter conversion can meaningfully raise total reaction output per rotation.
Step-by-Step Rotation for Maximum Formula Value
To actually convert the formula's theoretical damage into real numbers, follow this tested rotation structure:
Apply Cryo Aura First
Open with a fast Cryo application — the Traveler's skill or Ganyu's charged shot — so the enemy carries the aura before any Stellar-aligned hit lands.
Lock With Freeze
Follow with Hydro application (Ayato, Xingqiu) to freeze the target, extending the reaction window and unlocking the bonus Shatter component.
Trigger With Your Stellar Source
Hit the frozen target with your Stellar-aligned application to fire Stellar Glimmer at full formula value.
Respect the Internal Cooldown
Alternate Cryo and Stellar applications every 2–3 seconds. Triggering inside the internal cooldown wastes the application and drops your uptime.
Loop and Maintain 80%+ Uptime
Repeat the cycle with sustain supports (Charlotte, Mika) keeping the team alive through longer field time needed for stacking Stellar-Conduct triggers.
Aim to keep Stellar Glimmer uptime above 80% across a rotation. Sustain-heavy lineups with two healers are specifically built to enable this longer field time.
Scaling Checklist and Stat Priorities
Because level scaling dominates early and EM plus dedicated bonuses dominate late, your investment plan should shift as you progress. Use this checklist to audit your build:
Damage Formula Optimization Goals:
- Level the trigger character to 90 for maximum Level Multiplier
- Stack Elemental Mastery on reaction-focused drivers
- Secure a dedicated Stellar Glimmer damage bonus source
- Build sustain supports for 80%+ reaction uptime
- Practice Cryo-first application order until consistent
Stat priority by build role:
| Role | Priority Stats | Recommended Set Direction |
|---|---|---|
| Cryo on-field carry | CRIT Rate, CRIT DMG, ATK%, EM | Blizzard Strayer (40% CRIT swing vs Frozen) |
| Off-field trigger | ER%, CRIT, Elemental DMG | Emblem of Severed Fate / Golden Troupe |
| Anemo support | Elemental Mastery, ER | Viridescent Venerer (40% Cryo RES shred) |
| Budget support | ER%, EM | Instructor (party-wide +120 EM) |
Elemental Mastery appears directly inside the formula's multiplier, so a single Viridescent Venerer Swirl or an Instructor 4-piece buff raises every subsequent Stellar Glimmer instance — not just the wielder's damage.
FAQ
Q: What is the Stellar Glimmer damage formula?
Reaction Damage = Base Reaction Damage × (1 + Elemental Mastery Bonus + Stellar Glimmer Bonus) × Level Multiplier. Level scaling is the dominant factor early on, while Elemental Mastery and dedicated Stellar Glimmer bonuses define the late-game ceiling.
Q: Why is my Stellar Glimmer not triggering?
The enemy must carry a Cryo aura or be Frozen before the Stellar-aligned application hits. If the Stellar source lands first, it only applies aura without triggering the reaction. Apply Cryo first, then trigger.
Q: Which variant deals more damage, Stellar Swirl or Stellar-Conduct?
Stellar-Conduct has the higher single-target potential thanks to its stacking bonus for consecutive triggers, making it best for bosses. Stellar Swirl has a lower per-target multiplier but spreads the mark to nearby enemies, making it better for grouped AoE content.
Q: Does Freeze change the damage formula result?
Yes. Hitting a Frozen enemy extends the freeze window and converts part of the reaction damage into a bonus Shatter instance when the freeze breaks, effectively adding a second damage instance on top of the standard formula output.
