What’s New in Update 0.26?

This update introduces several key features:

  • New boss on Blossom Haven Island
  • Trader event with a new currency
  • Mintwolf evolution line expansion
  • SS Rank upgrade system
  • Pet gear improvements

While none of these are massive on their own, together they add more ways to progress and farm.


Trader Event Explained (Best New Feature)

One of the biggest additions is the Trader Event, which introduces a limited-time shop system.

How It Works:

A mysterious merchant appears near dungeons (Skyheart Isle). You earn Wanderer Coins by:

  • Defeating monsters
  • Clearing dungeons (around 500 coins per run)
  • Daily login rewards

You can also buy coins if you want

Shop System:

  • Costs 1,000 coins to buy or refresh
  • Items are random
  • Every purchase increases the price by +500 coins

Why It Matters:

The shop can give extremely strong monsters, including:

  • High-rank units (A and even S rank)
  • Monsters with multiple mutations

This makes it one of the fastest ways to get strong units right now.


Is the Trader Event Too Strong?

This is where opinions are split.

Pros:

  • Helps new players catch up quickly
  • Gives access to powerful monsters without long grinding

Cons:

  • Reduces the value of grinding
  • Players can get rare monsters much faster than before

If you’re farming seriously, this event can feel a bit unbalanced.


New Monsters and Evolutions

The update also expands the monster roster.

New Additions:

  • Emberwolf (Fire Mintwolf variant)
  • Sleetwolf (Water Mintwolf variant)
  • Thunderclaw (New boss)
  • Mentawolf (Secret Mintwolf evolution)

How to Get Mintwolf Secret Evolution

To unlock Mentawolf, you need:

  • 16 special materials dropped from Thunderclaw
  • Around 27 Enhanced Grass Gems

Even with everything prepared, the chance is still relatively low (around 18%), so expect some grinding.


New Boss: Thunderclaw

The newest boss is located on Blossom Haven Island, and it’s not an easy fight. Around 70 billion HP:

Drops:

  • Evolution materials
  • Eggs

Requires strong monsters to defeat

Tips:

  • Bring high-damage units
  • Focus on survivability
  • Farm with a group if possible

SS Rank System (New Progression)

A new upgrade system has been added for Blossom Haven monsters.

How It Works:

  • Use SS Ascension Slates
  • Requires 5 slates per monster

Notes:

  • Lets you push monsters to SS Rank
  • Stats can be checked in the index

This system is powerful but requires a heavy grind.


Pet Gear Improvements (QoL Update)

A small but useful change:

  • You can now see which monster is using each gear
  • Gear can be unequipped directly from the menu

This makes managing your setup much easier.


Is This Update Worth It?

This update feels more like a catch-up patch rather than a major expansion.

What It Does Well:

  • Makes progression faster
  • Adds more farming options
  • Introduces a solid event system

What It Lacks:

  • Limited new gameplay content
  • Some features feel grind-heavy
  • Balance between new and old players feels uneven

Update 0.26 doesn’t completely change Catch A Monster, but it does make progression more accessible. The trader event alone can speed up your progress a lot, especially if you get lucky with shop rolls. At the same time, the update raises questions about balance, especially for players who spent hours grinding for rare monsters. Still, if your goal is to build a strong team faster, this update gives you more ways to do it.
