Events in Catch a Monster are usually the best time to upgrade your collection, and the Frost Evolution event is one of the more rewarding ones so far. It’s simple on the surface, but if you understand how everything connects—from farming coins to evolving Frostwyrm—you can get much more out of it. Here’s a full breakdown so you don’t miss anything important. Also check out our Catch a Monster Codes for more rewards!
Frost Evolution Event Overview
The Frost Evolution event revolves around one main mechanic: earning Frost Coins. The good part is that you don’t need to grind actively all the time. You can:
- Stay online in-game
- Passively earn Frost Coins over time
These coins can then be used to claim a variety of rewards, making it one of the easiest events to farm.
Best Rewards from Frost Coins
Frost Coins can be exchanged for several useful items, especially if you’re trying to improve your pets. Some of the notable rewards include:
- Fiery Vial
- Rank upgrade materials (A → S rank)
- Special dungeon rewards
One highlight is the Thunder Room M, which has about a 30% chance to give the pet Fiery. That’s a solid rate compared to most event drops, making it worth prioritizing.
How to Evolve Frostwyrm into Avalanchewyrm
This is the main goal for many players during the event. To evolve your Frostwyrm, you need:
- 25 Refined Ice Gems
- 2 Refined Water Gems
Once you combine these materials, you’ll have about a 17% chance to successfully evolve it into Avalanchewyrm. The success rate is relatively low, so expect multiple attempts. It’s better to farm extra materials instead of relying on a single try. Focus on collecting gems consistently before attempting the evolution.
How to Get Evolution Materials
Refined gems usually come from:
- Event rewards
- Dungeon runs
- Exchange shops
Since the event already gives you Frost Coins passively, use them wisely to grab materials whenever possible.
Nightmare Mode (New Dungeon Difficulty)
The event also introduces Nightmare Mode in dungeons. This mode is:
- Much harder than standard runs
- Designed for late-game players
- Risky without strong pets and upgrades
If your team isn’t ready, it’s better to skip this for now and focus on farming safely.
How to Get Void Monsters
Another addition during this event is the Void Card system.
To use it:
- Go to the Void spawn location
- Interact with the Void Card
- A random monster will appear
Possible outcomes include:
- Octane
- Litter Box
- Dust-type monsters
This is completely RNG-based, so you may need multiple attempts to get what you want.
To make the most out of this event, keep things simple and consistent. Stay online as much as possible to stack Frost Coins passively. Use those coins to prioritize upgrade materials instead of random rewards.
At the same time, run dungeons when you can to gather refined gems for Frostwyrm evolution. If you’re aiming for Avalanchewyrm, patience is key. With only a 17% success rate, you’ll likely need several attempts before getting it.
The Frost Evolution event is one of the more relaxed events in Catch a Monster, since you can progress even while idle. At the same time, it offers strong rewards, especially if you’re targeting high-tier evolutions like Avalanchewyrm. If you stay consistent with farming and manage your resources properly, you’ll walk away from this event with stronger pets and better progression overall.
