Catch a Monster Dungeon & Frostwyrm EVO Update Guide (April 2026)

If you have been grinding through Catch a Monster on Roblox, the Dungeon and Frostwyrm EVO update is the biggest content drop the game has seen in a while. This update brings an entirely new dungeon system, Nightmare mode for hardcore players, and the Frost Evolution event that lets you transform Frostwyrm into the devastating Avalanchewyrm. Our team has spent hours testing every mechanic, farming every material, and running dungeons on both difficulties to put together this guide.

Whether you are hunting for Pokemon alternatives on Roblox or just want to know how to get Avalanchewyrm, this guide covers everything from finding Frostwyrm to beating Nightmare mode. The Frost Evolution event is time-sensitive, so understanding the mechanics fast will save you hours of grinding.

What Is the Dungeon and Frostwyrm EVO Update in Catch a Monster?

The Dungeon and Frostwyrm EVO update is a major content patch for Catch a Monster (Roblox) that introduces three core features: a new dungeon system with multiple difficulty tiers, the Frost Evolution event, and void pets. The dungeon system gives players repeatable PvE challenges with escalating difficulty and better rewards at each tier. Nightmare mode sits at the top, offering the best drops but requiring a well-built team.

The Frost Evolution event is the star of the update. It centers on Frostwyrm, an ice-type boss monster that can be caught and evolved into Avalanchewyrm. This evolution is one of the most powerful transformations in the game right now, making the grind absolutely worth it for players pushing into endgame content.

Void pets are a new category of monsters introduced alongside this update. They have unique abilities and can be obtained through dungeon rewards and special encounters. The gear event running alongside the update also gives players a chance to pick up exclusive equipment that boosts ice-type monsters specifically.

How the Evolution System Works in Catch a Monster

Before jumping into Frostwyrm specifically, you need to understand how evolution works in Catch a Monster. The evolution system lets you transform pets into more powerful forms by consuming specific materials at the Pet Evolution Kiosk. This kiosk is located on Skyheart Isle, which serves as the hub for all evolution activities.

Every evolution requires a combination of raw gems, refined gems, and special monster-specific materials. Raw gems drop from defeating monsters in the wild and inside dungeons. You refine raw gems into refined gems at the same kiosk, though this process takes time and can be done while AFK. Each monster has an EM value (Evolution Material value) that determines the quality and quantity of materials needed.

Here is the general process for evolving any monster in Catch a Monster:

Step 1: Catch or obtain the base monster you want to evolve. Make sure it is at or near max level for the best results.

Step 2: Gather the required materials. Check the evolution recipe at the Pet Evolution Kiosk on Skyheart Isle to see exactly what you need. Recipes vary by monster.

Step 3: Collect raw gems from battles and dungeons. Convert them to refined gems at the kiosk. This step takes the longest and is where most players get stuck.

Step 4: Gather any special materials specific to that monster (like Frostfeather Shards for Frostwyrm). These typically drop from the boss version of that monster.

Step 5: Return to the Pet Evolution Kiosk with all materials and initiate the evolution. There is an RNG element to the result, so you may get different stat rolls on the evolved form.

The chaos potion and mutation system add another layer. Some evolutions have a chance to trigger a mutation, producing a variant with different stats or abilities. This is separate from the standard evolution and is not something you can control directly.

How to Evolve Frostwyrm into Avalanchewyrm

Evolving Frostwyrm into Avalanchewyrm is the main goal of the Frost Evolution event. Avalanchewyrm is one of the most powerful ice-type monsters in the game right now, and players on Reddit and TikTok are calling it a must-have for competitive teams. The evolution process follows the standard system but requires specific materials that are only available during this event and from the Frostwyrm boss.

Where to Find and Catch Frostwyrm

Frostwyrm appears as a boss encounter in the new dungeon. You cannot find it roaming in the wild. The boss spawns at specific intervals inside the dungeon, and catching it requires legendary spheres. Regular spheres will not work on the Frostwyrm boss, so stock up before heading in.

Players have confirmed that Frostwyrm appears in both normal and Nightmare dungeon modes, but Nightmare mode offers a guaranteed encounter with a higher-stat version. If you are serious about getting the best possible base Frostwyrm for evolution, Nightmare mode is the way to go despite the difficulty spike.

Materials Needed for Frostwyrm Evolution

You need two key materials to evolve Frostwyrm into Avalanchewyrm:

Frostfeather Shards — These drop from the Frostwyrm boss with a community-verified 60% drop rate. Each evolution attempt requires a specific number of shards, so plan on running the boss multiple times. The drop rate is generous compared to other boss materials, which makes the grind manageable.

Refined Ice Gems — These are obtained by refining raw Ice Gems at the Pet Evolution Kiosk. Raw Ice Gems drop from ice-type monsters throughout the game and inside the dungeon. The refining process takes time. Players report that grinding enough refined gems takes literally hours, but you can AFK during the refining process itself.

The total material cost for one evolution attempt is significant, so do not expect to get it done in one session unless you have been stockpiling gems beforehand.

Step-by-Step Frostwyrm Evolution Process

Here is exactly how to evolve your Frostwyrm into Avalanchewyrm:

Step 1: Catch Frostwyrm from the dungeon boss encounter using legendary spheres. Aim for a high-level, high-rank catch if possible.

Step 2: Level your Frostwyrm to max level. The evolution kiosk requires your monster to be at max level before the option to evolve appears.

Step 3: Farm Frostfeather Shards by repeatedly defeating the Frostwyrm boss in the dungeon. With a 60% drop rate, most players will accumulate enough shards in 5-8 boss kills.

Step 4: Farm raw Ice Gems from ice-type monsters and dungeon runs. Convert them to Refined Ice Gems at the Pet Evolution Kiosk. This step can be done AFK.

Step 5: Travel to Skyheart Isle and approach the Pet Evolution Kiosk. Select Frostwyrm from your roster.

Step 6: Confirm you have all required materials displayed in the evolution recipe. The kiosk will show exactly what is needed.

Step 7: Initiate the evolution. The result has an RNG component, meaning the exact stat distribution on your Avalanchewyrm may vary. If you are unhappy with the result, you will need to gather materials for another attempt.

Community members have shared that Frostwyrm at max level shiny rank A is already a monster, and Avalanchewyrm takes those stats even further. The evolution is absolutely worth the investment for any player serious about their team composition.

Catch a Monster Dungeon Guide: Normal and Nightmare Mode

The dungeon system is the backbone of this update. It provides repeatable content that rewards materials, gear, and encounters with the Frostwyrm boss. Understanding the dungeon mechanics is essential whether you are farming materials or pushing for the hardest content. No other written guide currently covers both normal and Nightmare modes in detail, so this section should help fill that gap.

How to Unlock the New Dungeon

The new dungeon unlocks automatically for players who have reached mid-game progression. If you have been playing Catch a Monster for a while and have a team of leveled monsters, you should have access. The dungeon entrance appears on the map after a short introductory quest that explains the Frost Evolution event.

New players will need to progress through the main story and level their team before the dungeon becomes available. There is no specific level requirement published in-game, but based on community reports, having a team of monsters around level 40 or higher is the practical minimum for normal mode.

Nightmare Mode Strategies

Nightmare mode is where things get serious. Enemy stats are dramatically increased, and boss encounters have additional mechanics that do not appear in normal mode. Running Nightmare mode without a proper team composition will result in quick losses.

The best approach for Nightmare mode is to build a team with strong elemental coverage. Since the dungeon is ice-themed, fire-type monsters excel here. Bring at least one fire-type damage dealer and a tank that can survive the boss AoE attacks. Burn and poison status effects are extremely effective against the Frostwyrm boss in Nightmare mode, so prioritize monsters that can apply these conditions.

Avoid bringing paladin-type monsters that rely on mercy hit or ring of mercy mechanics. Community testing has confirmed that these abilities do not work on the Frostwyrm boss. This is a critical detail that catches many players off guard.

Here are key Nightmare mode tips that players have verified:

Bring legendary spheres for the boss encounter. Normal spheres will not capture Frostwyrm.

Stack burn and poison effects on the boss for consistent damage over time.

Do not rely on mercy hit or ring of mercy abilities. They are disabled for this boss.

Expect the fight to last longer than normal mode. Pack healing items and plan for endurance.

A well-built team can clear Nightmare mode consistently, but it takes preparation. Do not attempt it under-leveled or you will waste time and resources.

How to Beat the Frostwyrm Boss

The Frostwyrm boss fight is the centerpiece of the dungeon. Whether you are running normal or Nightmare mode, the boss has specific patterns you need to learn. The Frostwyrm uses powerful ice-type AoE attacks that can wipe an unprepared team in seconds.

The key to beating Frostwyrm is elemental advantage and status effects. Fire-type attacks deal bonus damage. Burn and poison deal consistent damage over time, which is especially effective because the boss has a large health pool. Do not try to burst it down with raw damage alone.

Position your tank to absorb the AoE hits while your damage dealers apply burn and poison. Once those status effects are stacked, the boss health bar will drop steadily even while you focus on surviving the attack patterns. This strategy works on both normal and Nightmare difficulties, though Nightmare requires better gear and higher levels to survive the hits.

Catching the boss requires legendary spheres, as mentioned earlier. Time your throw carefully. The catch window appears during specific boss animation phases. Throwing a sphere at the wrong time wastes it. Community players recommend watching for the stagger animation after a heavy combo before throwing.

Dungeon Rewards and Drop Table

The dungeon offers different reward tiers based on difficulty. Normal mode drops raw gems, standard gear, and has a chance to spawn the Frostwyrm boss encounter. Nightmare mode drops refined gems at a higher rate, exclusive gear pieces from the frost gear event, and guarantees a Frostwyrm boss encounter.

Both modes drop general materials that are useful for various evolutions. If you are specifically farming for the Frostwyrm evolution, Nightmare mode is more efficient per run despite the longer clear time. The guaranteed boss spawn and better material drops offset the additional difficulty.

The gear event running alongside the dungeon drops frost-themed equipment that boosts ice-type monster stats. If you plan to use Avalanchewyrm on your team, farming these gear pieces should be a priority alongside your material grinding.

Material Farming Guide: Frostfeather Shards and Refined Gems

Material farming is where most players spend the bulk of their time during this update. The two materials you need most are Frostfeather Shards and Refined Ice Gems, and they require different farming approaches. Understanding the most efficient methods will save you significant time.

Farming Frostfeather Shards is straightforward but requires boss kills. Each Frostwyrm boss defeat has a 60% chance to drop a Frostfeather Shard. Since the boss spawns inside the dungeon, you will be running the dungeon repeatedly. On average, you can expect to get a shard roughly every two boss kills. The drop rate is player-verified and consistent.

For the most efficient shard farming, focus on normal mode if your team is not ready for Nightmare. Normal mode is faster to clear, and the 60% drop rate applies on both difficulties. Nightmare mode is better if you also need refined gem drops alongside shards, since you get both in a single run.

Farming Refined Ice Gems is a longer process. Raw Ice Gems drop from ice-type monsters throughout the game, not just in the dungeon. The best location for raw gem farming is Sakurajima Island, where you can open chests and collect debris that frequently contain raw gems. Multiple players have recommended this spot for efficient gem collection.

Once you have raw gems, you refine them at the Pet Evolution Kiosk. The refining process takes time but can be done AFK. Players report that gathering enough refined gems for a single evolution attempt takes several hours of combined farming and refining. Starting the refining process before you have finished collecting shards is a smart way to parallelize the grind.

Here is an efficient farming routine that several community members recommend:

Start by sending raw gems to refine at the kiosk. This begins the AFK timer immediately.

While gems are refining, run the dungeon for Frostfeather Shards and additional raw gem drops.

Use any downtime to farm on Sakurajima Island for extra raw gems from chests and debris.

By the time you have enough shards, your refined gems should be close to or already finished.

This approach cuts the total farming time significantly compared to doing each step sequentially. Players who batch their farming this way report completing the full material requirements in about half the time of players who farm shards and gems separately.

Pro Tips for the Frost Evolution Event

Beyond the basic mechanics, there are several strategies that experienced players use to maximize their efficiency during the Frost Evolution event. These tips come from community discussions, Reddit threads, and content creator videos.

Is Frostwyrm worth evolving? Yes, without question. At max level shiny rank A, Frostwyrm is already one of the stronger ice-type monsters. Avalanchewyrm takes those base stats and amplifies them significantly. Players who have completed the evolution describe it as a game-changer for both PvE dungeon content and competitive play.

Best team composition for frost dungeon content centers around fire-type damage dealers and a sturdy tank. The dungeon is ice-themed, so fire coverage is non-negotiable for efficient clears. Bring a healer if you are attempting Nightmare mode, since the boss AoE damage is relentless. Status effect monsters that can apply burn and poison are more valuable here than raw damage dealers.

Void pets are a new addition worth exploring alongside the main event. These monsters have unique abilities that differentiate them from standard catches. Void pets are obtained through dungeon rewards and special encounters. While they are not required for the Frostwyrm evolution, they add variety to your team and some have synergy with ice-type compositions.

Level your Frostwyrm before evolving. The evolution result is influenced by the base monster level and stats. Catching a higher-level Frostwyrm from Nightmare mode and leveling it to max before evolving gives you a stronger Avalanchewyrm. Do not rush the evolution with an under-leveled base monster.

Stockpile materials early. The Frost Evolution event has a limited duration. Start farming raw gems and running the dungeon as soon as the event goes live. Players who wait until the final days often find themselves short on materials when the event ends. If you enjoy RPGs with monster catching mechanics, you know that preparation before limited-time events always pays off.

The gear event is worth your time. The frost-themed gear from the concurrent gear event provides stat bonuses to ice-type monsters. If you are investing resources into evolving Frostwyrm, farming the gear that makes Avalanchewyrm even stronger is a logical next step. The gear drops from both dungeon difficulties, with Nightmare mode offering the best pieces.

AFK farming works for refining but not for shards. The gem refining process can run while you are away from the game. Frostfeather Shards require active boss kills. Plan your play sessions around these two different requirements to avoid wasting time sitting at the kiosk when you could be running dungeons.

Wrapping Up the Dungeon and Frostwyrm EVO Update

The Catch a Monster Dungeon and Frostwyrm EVO update delivers meaningful endgame content with the dungeon system, Nightmare mode challenges, and the powerful Frostwyrm to Avalanchewyrm evolution. The key takeaway is that preparation matters: start farming materials early, level your Frostwyrm to max before evolving, and build a team with fire-type coverage and status effect capabilities for the dungeon.

Avalanchewyrm is absolutely worth the investment. The material grind is real, especially for Refined Ice Gems, but the parallel farming strategy of refining gems while running dungeons for shards cuts the total time dramatically. For players looking to explore more open-world games with creature catching, the dungeon system in this update adds a new dimension to the Catch a Monster experience.

The Frost Evolution event is limited, so prioritize your farming now rather than waiting. Grab those legendary spheres, stack your burn and poison monsters, and head into the dungeon. Avalanchewyrm is waiting.
