- Stellar Glimmer reaction (Genshin Impact) is the flagship Cryo-linked reaction introduced in the 7.0 Snezhnaya version.
- Two variants exist: Stellar Swirl for AoE spread and Stellar-Conduct for single-target stacking.
- Trigger rule: enemies must carry a Cryo aura or be Frozen before the Stellar-aligned source hits.
- Best budget trigger: the Traveler's Cryo Resonation, unlocked through the Snezhnaya Archon Quest.
- Rotation key: alternate Cryo and Stellar applications every 2-3 seconds to keep reaction uptime above 80%.
Stellar Glimmer Reaction Mechanics in Genshin Impact
The Stellar Glimmer reaction is a Cryo-aligned reaction system added with the Snezhnaya version of Genshin Impact. It activates when a Cryo aura on an enemy is struck by a Stellar-aligned application. The order matters: if the enemy does not already carry Cryo (or a Frozen state), the hit only applies an aura and no reaction occurs.
The damage formula rewards sustained setup. Reaction damage equals Base Reaction Damage multiplied by (1 + Elemental Mastery Bonus + Stellar Glimmer Bonus) and a Level Multiplier. Early on, level scaling dominates; in the late game, Elemental Mastery and dedicated bonus stats define your ceiling.
Do not trigger with your Stellar source first. Always apply Cryo — ideally through a Freeze — before the Stellar-aligned hit, or the reaction will not fire at all.
Variant Comparison
| Variant | Targeting | Strength | Best Use Case |
|---|---|---|---|
| Stellar Swirl | Multiple enemies | Spreads the mark to nearby foes | AoE content, grouped waves |
| Stellar-Conduct | Single enemy | Stacking bonus per consecutive trigger | Boss fights, elite duels |
Stellar Swirl has a slightly lower per-target multiplier but excels when enemies cluster. Stellar-Conduct concentrates the full reaction on one target and rewards consecutive triggers, making it the preferred pick against bosses.
Frozen and Shatter Interaction
Hitting a Frozen enemy with Stellar Glimmer extends the freeze window, and part of the reaction damage converts into a bonus Shatter instance when the freeze breaks. This rewards teams that stack Cryo application before triggering — Hydro enablers like Kamisato Ayato are therefore natural partners.
How to Trigger Stellar Glimmer: Step-by-Step
Follow this sequence in every fight to trigger the reaction reliably and maintain high uptime.
Apply Cryo First
Open with a Cryo skill or burst to place a Cryo aura on the enemy. The Traveler (Cryo), Ganyu, or Ayaka all work as aura sources.
Hold with Freeze
Follow with Hydro application to freeze the target. Frozen enemies extend the reaction window and unlock the bonus Shatter component.
Trigger with Your Stellar Source
Strike the Cryo-carrying enemy with your Stellar-aligned application. In Snezhnaya regions, the Cryo Traveler's kit converts into a reliable trigger.
Respect Internal Cooldown
Alternate Cryo and Stellar applications every 2-3 seconds. This pacing keeps reaction uptime above 80% without wasting applications.
Loop the Rotation
Return to step one and repeat. In AoE fights, use Stellar Swirl; against bosses, chain Stellar-Conduct triggers for the stacking bonus.
Pair the Traveler (Cryo) with free off-field enablers such as Xingqiu or Fischl. Their consistent application lets a low-investment team sustain near-continuous Stellar Glimmer triggers.
Best Characters and Team Comps
Character value in this system is measured by elemental application frequency — how reliably a unit sustains Cryo aura or delivers Stellar triggers.
| Character | Element | Role | Application | Fit |
|---|---|---|---|---|
| Traveler (Cryo) | Cryo | Trigger / Enabler | Fast | S |
| Ganyu | Cryo | Main DPS | Moderate | S |
| Ayaka | Cryo | Main DPS | Fast | A |
| Kamisato Ayato | Hydro | Enabler | Fast | A |
| Charlotte | Cryo | Support | Moderate | B |
| Mika | Cryo | Support | Moderate | B |
Double Cryo Freeze Core
- Members: Ganyu / Ayaka / Ayato / Charlotte
- Freeze-lock enemies, trigger Stellar Swirl for AoE spreads
- Substitute Mona for Ayato
Traveler Boss Killer
- Members: Traveler (Cryo) / Ganyu / Mika / Ayato
- Single-target Stellar-Conduct stacking against bosses
- Substitute Ayaka for Ganyu
Sustain-Heavy Stellar Loop
- Members: Traveler (Cryo) / Charlotte / Ayato / Mika
- Long field time with healers enabling 80%+ uptime
- Substitute Ganyu for the Traveler
Prioritize one fast Cryo applicator, one Hydro or off-field enabler, and one sustain unit. Double Cryo resonance adds crit rate and energy, which directly improves trigger frequency.
Artifacts and Weapons for Stellar Glimmer Builds
Artifacts and weapons are the biggest multipliers you control. Build around Cryo damage, crit, and Elemental Mastery depending on each unit's role.
| Set | Best For | Key Effect |
|---|---|---|
| Blizzard Strayer | Cryo on-field carry, Traveler (Cryo) | Up to 40% CRIT Rate vs Frozen enemies (4pc) |
| Golden Troupe | Off-field skill sub-DPS | +25% Skill DMG, further +25% off-field |
| Viridescent Venerer | Anemo support | 40% Cryo RES shred on Swirl |
| Emblem of Severed Fate | Burst-reliant sub-DPS | Burst DMG scales with Energy Recharge |
| Instructor (4-Star) | Budget support | +120 party Elemental Mastery on Skill |
Main stats for Cryo carries: ATK% or EM sands, Cryo DMG goblet, CRIT circlet. Substats prioritize CRIT Rate, CRIT DMG, ATK%, and Elemental Mastery.
Craftable options like Amenoma Kageuchi and Iron Sting cover Burst uptime and Elemental Mastery without any pulls. Harbinger of Dawn remains a legendary budget crit stick for safe, shielded teams.
Beginner Goals and Checklist
New to Snezhnaya? Work through these milestones to get a functioning Stellar Glimmer team on a budget.
Stellar Glimmer Starter Milestones:
- Progress the Snezhnaya Archon Quest to unlock Cryo Resonation
- Resonate with a Statue of The Seven to gain the Cryo element
- Raise Traveler talents to 6/6/6 (Burst first, then Skill)
- Pair with free enablers: Xingqiu, Fischl, or Lisa
- Farm a Blizzard Strayer set after Adventure Rank 45
Snezhnaya zones feature harsh cold mechanics that drain party HP. Stay near torches and warming objects, upgrade Statues of The Seven early, and always bring a healer.
FAQ
Q: What is the Stellar Glimmer reaction in Genshin Impact?
Stellar Glimmer is the flagship Cryo-linked elemental reaction introduced with the 7.0 Snezhnaya version. It triggers when a Cryo aura (or Frozen state) on an enemy is struck by a Stellar-aligned application, with Stellar Swirl and Stellar-Conduct as its two variants.
Q: What is the difference between Stellar Swirl and Stellar-Conduct?
Stellar Swirl spreads the reaction mark to nearby enemies, making it ideal for AoE and grouped waves. Stellar-Conduct focuses the full reaction on one target with a stacking damage bonus for consecutive triggers, making it the boss-fight variant.
Q: How does the Cryo Traveler trigger Stellar Glimmer?
After resonating with a Statue of The Seven in Snezhnaya, the Traveler gains a Cryo skill set tuned for frequent application. Their skill and burst both apply Cryo reliably, and their kit converts to Stellar-aligned damage in Snezhnaya regions.
Q: Which characters are best for Stellar Glimmer teams?
Ganyu and the Cryo Traveler sit at S-tier for application frequency and reaction scaling. Ayaka and Ayato are excellent A-tier picks, while Charlotte and Mika provide solid off-field support for longer trigger windows.
