How to Get SS Rank Monster in Catch a Monster (Roblox Guide)

Getting an SS Rank monster in Catch a Monster is one of the biggest upgrades you can achieve in the game.

However, upgrading a monster to SS Rank is not something you can do immediately. Players need to collect special materials, craft Ascension Slates, and fuse several S Rank monsters together. The process can take time, but once you understand the steps, it becomes much easier to work toward your first SS Rank pet. Here is a full guide explaining how to unlock SS Rank monsters in Catch a Monster.


Step 1: Get Ascension Slate Materials from Dungeons

The main materials needed to create an SS Rank monster are Ascension Slates. These slates are required when upgrading a monster from S Rank to SS Rank. To obtain these materials, you should focus on running Dungeons.

  • Completing dungeons gives a chance to drop Slate pieces
  • These pieces usually drop as top halves of the slate
  • Hard mode dungeons provide better chances for higher-quality materials

Even if you play on normal difficulty, you still have a chance to receive slate pieces. However, players who can clear Hard Mode consistently will progress much faster.


Step 2: Buy Slate Pieces from the Daily Shop

Another place to get slate materials is the Daily Shop.

The shop sometimes sells bottom halves of Ascension Slates, which are needed to complete the tablet.

Important details about the shop:

  • Bottom halves can appear in the shop rotation
  • They usually cost around 15,000 tokens
  • The shop inventory changes regularly

Because dungeon drops usually give the top half, the shop is a reliable way to get the missing piece and complete the slate.


Step 3: Craft Full Ascension Slates

Once you collect both halves of the slate, the next step is crafting the full tablet.

To do this:

  1. Go to the Crafting Workshop
  2. Open the crafting menu
  3. Select the Ascension Slate recipe
  4. Combine the top half, bottom half, and dungeon materials

After crafting, you will receive a complete SS Ascension Slate, which is required for upgrading monsters.


Types of Ascension Slates

There are two main types of slates used for SS upgrades.

1. Blue Rank Slate

This slate is used to upgrade Legendary monsters. It is easier to obtain compared to the higher tier slate, which makes it a good option for your first SS Rank monster.

2. Higher Rank Ascension Slate

This slate is used for stronger monsters, including:

  • Mythical monsters
  • Boss monsters

These are harder to craft because they require rarer materials and more dungeon farming.


Step 4: Go to the Pet Center and Fuse Monsters

Once you have the required slates, head to the Pet Center and open the Fuse tab. To upgrade a monster to SS Rank, you need:

  • 6 S Rank monsters
  • 5 Ascension Slates

The monster you want to upgrade must already be S Rank. The remaining monsters are used as materials during the fusion process.


Important Rules When Upgrading to SS Rank

There are several important things to remember before starting the upgrade.

Evolved Monsters Cannot Become SS Rank

If your monster is already evolved, it may not appear in the fusion list. To upgrade it, you must:

  • Use a Reversion Potion
  • Reset the monster back to its base form
  • Then upgrade it to SS Rank

After that, you can evolve it again.

Basic Dummy Pets Cannot Be Used

Earlier in the game, players could use gray dummy pets as materials for SS upgrades. This method has now been removed. Currently, you can only use:

  • Epic monsters
  • Legendary monsters
  • Mythical monsters

All of them must be S Rank to count toward the fusion requirement.


Good Monsters to Upgrade First

If you are unsure which monster to upgrade first, many players recommend upgrading Hydrobit. This monster is considered one of the best Legendary pets with an evolution, making it a strong candidate for a first SS Rank upgrade. After that, you can focus on upgrading stronger monsters such as:

  • Voltgator
  • Celestite

But since higher-tier upgrades require better slates, it may take more farming before you reach that point.


Event Shop Shortcut (Easter Event)

During special events, there may be easier ways to obtain Ascension materials. For example, during the Easter Event Part 2, players can buy:

  • Full Blue Rank Slates for 40,000 Bunny Coins
  • Top half of higher Ascension Slates for 15,000 Bunny Coins

This allows players to skip some dungeon farming if they have enough event currency.


Getting an SS Rank monster in Catch a Monster takes time, but the process becomes straightforward once you understand where the materials come from. The key steps include farming dungeons, collecting slate pieces, crafting Ascension Slates, and fusing multiple S Rank monsters together. If you focus on running dungeons regularly, checking the shop for missing slate pieces, and saving your best monsters for fusion, you will eventually unlock your first SS Rank monster. Once you obtain one, progression becomes much easier, allowing you to clear harder content and farm even stronger monsters in the future.
