Genshin Melt vs Vaporize Comparison Tool: Which Reaction is Best?
In the high-stakes world of Genshin Impact theorycrafting, one question reigns supreme: Melt vs Vaporize? These are the "Amplifying" reactions—the only reactions in the game that directly multiply your base hit damage (including CRIT and ATK). While other reactions like Hyperbloom have high floors, Melt and Vaporize have the highest ceilings. Our Genshin Melt vs Vaporize Comparison Tool is designed to help you navigate the complex math of multipliers, gauge stability, and team-wide DPS.
The Multiplier Mystery: 1.5x vs 2.0x
It sounds simple: 2.0x is bigger than 1.5x, so Melt (Pyro on Cryo) should always be better than Vaporize (Pyro on Hydro). However, the game implements a balance mechanic often called "Forward" and "Reverse" reactions.
- Forward Melt (2.0x): Pyro hitting a Cryo aura. This is a "Strong" trigger that usually consumes the entire Cryo aura instantly.
- Reverse Melt (1.5x): Cryo hitting a Pyro aura. This is a "Weak" trigger that leaves some Pyro behind, allowing for multiple Cryo hits (e.g., Rosaria's Burst) to all Melt.
- Forward Vaporize (2.0x): Hydro hitting a Pyro aura. Used by characters like Childe (Burst) or Mona.
- Reverse Vaporize (1.5x): Pyro hitting a Hydro aura. The gold standard for characters like Hu Tao, Xiangling, and Yoimiya.
Why Consistency Wins: The "Aura Stability" Factor
The primary reason Vaporize is often favored over Melt for characters like Hu Tao is Aura Stability. Hydro is naturally "Sturdy" in the elemental system. A single application of Hydro from Xingqiu can support two or even three "Reverse Vaporize" hits from a Pyro character. Conversely, Pyro is "Fragile" when hitting Cryo. If you try to Melt every hit of a fast character like Hu Tao, you will quickly run out of Cryo, and your Hydro/Cryo support won't be able to keep up. This results in "Reaction Whiffs," where your damage drops to 1.0x (raw damage). Our comparison tool accounts for this Reaction Frequency % to give you a true DPS average.
The "Gauge Theory" Breakdown Table
| Interaction | Multiplier | Gauge Consumption | Stability Rating | Best Use Case |
|---|---|---|---|---|
| Forward Melt (Pyro > Cryo) | 2.0x | Heavy (2x) | Poor | One-shot nukes, slow big hits. |
| Reverse Melt (Cryo > Pyro) | 1.5x | Light (0.5x) | Excellent | Multi-hit Cryo bursts (Rosaria, Ayaka). |
| Forward Vape (Hydro > Pyro) | 2.0x | Heavy (2x) | Moderate | Fast Hydro application on a Pyronado. |
| Reverse Vape (Pyro > Hydro) | 1.5x | Light (0.5x) | Superior | Fast Pyro carries (Hu Tao, Xiangling). |
Elemental Mastery (EM) Scaling: The Secret Multiplier
EM doesn't just "add" damage; it provides a direct percentage increase to the base 1.5x or 2.0x multiplier. 1. A standard Hu Tao with 100 EM gains ~18% Vaporize damage. 2. Her 1.5x multiplier becomes 1.5 * (1 + 0.18) = 1.77x. 3. If she had 400 EM, that becomes 1.5 * (1 + 0.60) = 2.4x. Notice how the gap between 100 and 400 EM (2.4x vs 1.77x) is a massive increase in total output. The Melt vs Vaporize Optimizer helps you find the exact point where switching your ATK% Sands for an EM Sands results in a massive damage spike.
When Melt Becomes Viable: The "Sunfire" and "Burning" Tech
In the Version 4.x/5.x meta, we've seen new ways to enable Forward Melt (the 2.0x version). * **Sunfire Jean:** By stacking Bennett and Jean's bursts, you generate a Pyro pulse every second that is "Heavy" enough to support Cryo DPS Melts. * **Burning (Dendro + Pyro):** The Burning reaction provides a self-sustaining Pyro aura that is very difficult for Cryo to wash away, allowing characters like Ganyu or Wriothesley to Melt every hit consistently. Use our tool to compare these advanced team setups against standard Vaporize rotations.
Deep Dive: Hu Tao Vaporize vs. Hu Tao Melt
Many players ask: *"Should I run Hu Tao with Xingqiu and Yelan (Double Hydro) or Hu Tao with Xingqiu and Kaeya (Melt-Vape)?"* - **Double Hydro:** Consistent 1.5x Vaporize on 100% of hits. Total DPS is incredibly stable. - **Melt-Vape:** High probability of 2.0x Melt on some hits and 1.5x Vaporize on others. While the high numbers look better, the "Reaction Priority" often shifts. If Kaeya steals a Vaporize trigger, your overall team DPS might actually *drop* compared to the stability of Double Hydro. This tool models these multi-character interactions to find the winner.
Optimizing for "Total Rotation" vs "Critical Hits"
Don't be fooled by "Damage Showcases" on YouTube. A character hitting a 1-million damage Melt burst once every 5 minutes is often worse than a character hitting 50,000 damage Vaporize slashes twice every second. * **Burst-Focused (Melt):** If your character's damage is 80% concentrated in their Burst (e.g., Eula if her physical was Cryo, or Diluc's initial hit), hunt for the Melt. * **Rotation-Focused (Vaporize):** If your damage is spread across 10-20 hits over a 15-second window (e.g., Yoimiya), focus on the consistency of Vaporize.
Formula: How We Calculate the Comparison
We use the standard Genshin damage formula with a focus on the **Reaction Multiplier (RM)**: `Total Damage = Base ATK * Scaling% * (1 + Crit DMG) * RM * Bonus% * Defense% * Resistance%` Our comparison specifically isolates the **RM** variable: `RM = Base Multiplier * [1 + (2.78 * EM / (1400 + EM)) + Artifact_Bonus]` By holding all other variables constant, we can show you exactly how much your "Team Choice" is affecting your final damage output.
Advanced Strategy: "Double Swirling" for Dual Reactions
To truly optimize Melt and Vaporize, you must "Double Swirl" with an Anemo character like Kazuha. This involves reducing the Resistance of *both* the driving element (Pyro) and the reactive element (Hydro/Cryo). If you only shred Pyro, your Vaporize hits might be weaker than if you shred both. This comparison tool allows you to input separate "Res Shred" values for the trigger and the aura elements to model high-level Kazuha or Sucrose setups.
Conclusion: The Math of the Meta
Deciding between Melt and Vaporize isn't just about personal preference; it's a mathematical decision based on your character's hit rate, your support's application speed, and your artifact luck. The Genshin Melt vs Vaporize Comparison Tool gives you the clarity you need to stop guessing and start grinding. Optimize your artifacts, fix your rotations, and achieve the "Perfect Reaction" every time you enter the abyss.
