- Stellar Glimmer reaction dmg scales with character level, Elemental Mastery, and dedicated bonus stats.
- Trigger rule: the enemy must carry a Cryo aura (or be Frozen) before the Stellar source hits.
- Stellar Swirl spreads damage in AoE; Stellar-Conduct stacks single-target damage for bosses.
- Best triggers: Cryo Traveler and Ganyu lead the meta; Ayaka and Ayato follow closely.
- Rotation key: alternate Cryo and Stellar applications every 2–3 seconds to keep 80%+ uptime.
How Stellar Glimmer Reaction DMG Works
Stellar Glimmer is the Cryo-aligned reaction system introduced with the Snezhnaya version of Genshin Impact. Its damage output is not a flat number — it is the product of several scaling factors, and understanding each one is the difference between mediocre and meta-defining numbers.
The damage formula breaks down as follows:
Reaction DMG = Base Reaction Damage × (1 + Elemental Mastery Bonus + Stellar Glimmer Bonus) × Level Multiplier
| Scaling Factor | Impact | Priority |
|---|---|---|
| Character Level | Dominant early-game scaling through the Level Multiplier | Highest early |
| Elemental Mastery | Multiplies reaction damage directly; defines the late-game ceiling | Highest late |
| Stellar Glimmer Bonus | Dedicated reaction bonus stats from artifacts and weapons | Situational |
| Cryo Aura Uptime | No aura means no trigger at all | Mandatory |
If the Stellar source hits an enemy without a Cryo aura or Frozen status, the application only attaches the aura and no reaction occurs. Always apply Cryo first, then trigger.
Stellar Swirl vs Stellar-Conduct: Which Variant Deals More
The two variants of Stellar Glimmer serve opposite purposes. Picking the wrong one for the encounter is the most common damage loss players see.
| Variant | Targeting | Per-Target Multiplier | Best Scenario |
|---|---|---|---|
| Stellar Swirl | Spreads the mark to nearby enemies on trigger | Lower | AoE content, grouped waves |
| Stellar-Conduct | Focuses full reaction on one target | Higher, stacks on consecutive triggers | Bosses, elite single-target |
CardGrid comparison of the two playstyles:
Stellar Swirl Playstyle
- AoE spread on every trigger
- Pairs with grouping supports like Sucrose
- Lower per-target multiplier but total team damage climbs in packs
- Ideal for domains and wave-based events
Stellar-Conduct Playstyle
- Stacking damage bonus for consecutive triggers on one target
- Rewards long field time and sustain
- Best against bosses with large HP pools
- Freeze-lock the target to extend the stacking window
Hitting a Frozen enemy with Stellar Glimmer extends the freeze window and converts part of the reaction damage into a bonus Shatter instance when the freeze breaks. Stack Cryo application before triggering to capitalize on this.
Step-by-Step Rotation for Maximum Reaction DMG
Follow this rotation loop to respect the internal cooldown and keep reaction uptime above 80%.
Apply the Cryo Aura
Open with a fast Cryo application — the Traveler's Elemental Skill or Ganyu's charged shot. Confirm the enemy carries the aura before moving on.
Lock with Freeze
If running a Hydro enabler like Ayato or Xingqiu, apply Hydro to freeze the target. This extends the reaction window and unlocks the Shatter bonus component.
Trigger with Your Stellar Source
Hit the Cryo-aura enemy with your Stellar-aligned application to trigger Stellar Glimmer and deal reaction damage.
Alternate Every 2–3 Seconds
Respect the internal cooldown by alternating Cryo and Stellar applications. Spamming one element wastes triggers to ICD.
Loop and Stack
In Stellar-Conduct setups, keep the loop running to build the consecutive-trigger stacking bonus; in Swirl setups, re-group enemies between loops.
A well-run rotation maintains above 80% reaction uptime. If your damage logs show long gaps between Stellar Glimmer instances, your application frequency — not your stats — is the bottleneck.
Best Characters and Teams for Reaction DMG
Trigger fit depends on elemental application frequency. These ratings reflect how reliably each character sustains the 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 |
| Ayato | Hydro | Enabler | Fast | A |
| Charlotte | Cryo | Support | Moderate | B |
| Mika | Cryo | Support | Moderate | B |
Two proven archetypes for maximizing Stellar Glimmer reaction dmg:
| Comp | Members | Strategy | Rotation Loop |
|---|---|---|---|
| Double Cryo Freeze Core | Ganyu / Ayaka / Ayato / Charlotte | Freeze-lock, trigger Stellar Swirl for AoE spreads | Ayato skill → Ganyu burst → Ayaka combo → repeat |
| Traveler Stellar-Conduct Boss Killer | Traveler (Cryo) / Ganyu / Mika / Ayato | Single-target stacking against bosses | Ganyu skill → Traveler skill → Ayato burst → Traveler burst → Mika buffs → loop |
The Cryo Traveler's skill applies Cryo on a short cooldown and converts to Stellar-aligned damage in Snezhnaya regions, making them the most accessible trigger unit — no five-star pulls required for a functional Stellar-Conduct core.

Build Checklist for Reaction DMG Optimization
Damage Optimization Milestones:
- Level your trigger character to 90 for the Level Multiplier
- Stack Elemental Mastery on the reaction trigger (sands EM/ATK%)
- Equip Blizzard Strayer 4-piece on on-field Cryo carries
- Alternate Cryo and Stellar applications every 2-3 seconds
- Maintain 80%+ reaction uptime across the rotation loop
FAQ
Q: What stats increase Stellar Glimmer reaction dmg the most?
Early on, character level dominates through the Level Multiplier. In late game, Elemental Mastery and dedicated Stellar Glimmer bonus stats define the damage ceiling. Reaction DMG = Base Reaction Damage × (1 + EM Bonus + Stellar Glimmer Bonus) × Level Multiplier.
Q: Why is my Stellar Glimmer not triggering?
The enemy must carry a Cryo aura or be Frozen before the Stellar source hits. If the Stellar application lands first, it only attaches the aura without triggering the reaction. Apply Cryo first, then trigger.
Q: Stellar Swirl or Stellar-Conduct for bosses?
Stellar-Conduct. It focuses the full reaction on a single target and adds a stacking damage bonus for consecutive triggers, making it the preferred variant for boss fights and elite single-target rotations. Stellar Swirl's spread has a lower per-target multiplier.
Q: Does Freeze improve Stellar Glimmer damage?
Yes. Hitting a Frozen enemy with Stellar Glimmer extends the freeze window and converts part of the reaction damage into a bonus Shatter instance when the freeze breaks. Pairing a Hydro enabler like Ayato with your Cryo core significantly raises total damage.
