catch a monster ascension core Materials

The term ascension core is often used for the materials needed to push an S-rank monster toward SS rank. In the current progression loop, the important items are rank slates, slate halves, full tablets, and dungeon crafting materials. Your first priority is identifying which tablet tier matches the monster you want to upgrade.

Video Highlights:

  • Find rank materials through dungeon difficulty and rotating shops.
  • Combine upper and lower slate halves at the crafting workshop.
  • Compare tablet quality before committing valuable S-rank pets.
  • Check the Pet Center fusion tab for the exact requirement.
Material SourceMain UsePractical Note
Easy dungeonChance at upper slate halves and crafting materialsUseful for steady early farming
Hard dungeonChance at higher-tier upper halvesRequires stronger combat preparation
Daily dungeon shopOften offers lower halvesStock and prices can rotate
Event shopMay offer full blue slates or special halvesSave event currency for priority upgrades
Crafting workshopCombines halves into full tabletsRequires both halves and additional materials
Start With the Target

Choose the monster first, then farm its tablet tier. This prevents spending dungeon materials on a slate that cannot support your intended fusion.

How to Farm the Right Ascension Materials

Dungeon runs are the most dependable starting point for ascension preparation. Normal and hard modes can provide different portions of rank slates, while the dungeon shop can help fill gaps when a particular half does not drop quickly. Shop inventories are not guaranteed, so check them regularly rather than spending all currency immediately.

During the Easter event described in the available 2026 material, the event shop offered full blue rank slates for 40,000 bunny coins and a higher-rank upper half for 15,000 bunny coins. Event prices and availability can change, so treat these as dated reference values rather than permanent rules.

1

Select an SS Candidate

Pick the monster you want to improve and confirm whether it is legendary, mythical, or boss type. This determines which tablet quality you should pursue.

2

Run the Dungeon

Farm the easiest difficulty you can clear consistently. Move to hard mode when you need a chance at higher-tier upper slate halves.

3

Check Rotating Shops

Review the daily dungeon shop and any active event shop for lower halves, full blue slates, keys, or other required materials.

4

Craft the Full Tablet

Take matching upper and lower halves, plus the additional dungeon materials, to the crafting workshop and create the complete rank tablet.

Farming ActivityBest Reason to Use ItMain Limitation
Easy dungeonReliable repeated runs and upper-half chancesMay not provide higher-tier pieces
Hard dungeonBetter access to advanced slate halvesRequires a stronger team
Daily shopFills a missing lower-half slotInventory and cost can vary
Event shopCan shorten the crafting pathLimited event currency and availability
Restock ticketRefreshes a shop for another chanceDoes not guarantee the needed item
Do Not Rush Shop Spending

Keep enough tokens for the exact half or tablet you need. Buying unrelated dungeon materials early can delay the upgrade you are already farming toward.

Tablet Tiers and Monster Compatibility

Tablet quality matters more than simply owning a large number of slates. The blue rank slate is associated with legendary monsters, while the higher-quality slate is used for mythical and boss-type monsters. The fusion interface shows the required tablet count when you select an eligible S-rank monster.

The available guide confirms that five lower-quality blue tablets can be exchanged for one higher-quality tablet. This exchange can solve a shortage, but it is expensive because it converts several completed items into one advanced item. Use it only after deciding that the target monster justifies the trade.

Blue Rank Slate

  • Used for legendary targets
  • Can be crafted from matching halves
  • A strong path for evolved legendary candidates

Higher Rank Slate

  • Used for mythical or boss targets
  • Requires more demanding materials
  • Check the fusion screen before farming

S-Rank Fodder

  • Six eligible S-rank pets may satisfy the rank requirement
  • Epic, legendary, and mythical S-rank pets can qualify
  • Gray dummy pets are not accepted in the current method
Target CategoryRecommended MaterialPlanning Advice
Legendary monsterBlue rank tabletConsider a strong legendary with an available evolution
Mythical monsterHigher-quality tabletSave advanced tablets before collecting fodder
Boss monsterHigher-quality tabletVerify eligibility directly in the fusion interface
Evolved S-rank monsterMay require reversion firstReset, fuse, then evolve again if the target is unavailable
Read the Fusion Requirement

The Pet Center is the final authority for your current inventory. Select the monster and confirm the tablet tier and fodder count before using any materials.

S-Rank Fodder and Fusion Preparation

An SS upgrade is not only a tablet check. The fusion screen also requires a group of eligible S-rank pets. The documented method shows a requirement of six S-rank pets for the demonstrated target, with five higher-quality tablets listed separately. Fodder does not necessarily need to match the target’s monster category, but it must be accepted by the interface.

Gray dummy pets are a poor assumption for current progression. They were reportedly usable in an earlier version of the system, but the demonstrated method no longer accepts them. Epic, legendary, and mythical S-rank pets can be used when the fusion screen recognizes them as valid materials.

Preparation CheckWhat to ConfirmWhy It Matters

SS Ascension Preparation:

  • Choose a legendary, mythical, or boss target
  • Confirm the correct tablet tier in the Pet Center
  • Collect six eligible S-rank pets
  • Craft the required full tablets
  • Use reversion first if an evolved target is unavailable
Protect Your Best Monsters

Use weaker eligible S-rank pets as fodder when possible. Avoid sacrificing a monster that is already part of another evolution or team plan.

Best Upgrade Priorities and FAQ

For many players, the most efficient first project is a legendary monster with a useful evolution and a realistic tablet requirement. The available progression example identifies Hydribit as a strong legendary candidate when using lower-tier tablets. Higher-tier goals such as mythical or boss monsters can be saved for later, once your dungeon clear speed and material income improve.

A practical order is to secure the target, farm the appropriate dungeon, use shops to complete missing pieces, and only then gather fusion fodder. This keeps your inventory flexible and reduces the chance of converting valuable tablets before you know which monster will receive them.

Upgrade PriorityRecommended ActionReason

Recommended Farming Route

Farm the dungeon first, inspect the daily shop second, use event currency only for a clear upgrade goal, and craft after both slate halves are secured.

Q: What is the catch a monster ascension core used for?

It refers to the rank-up materials used for SS progression. In the current method, these materials are represented by slate halves, full rank tablets, and related dungeon ingredients.

Q: Where can I get ascension slates?

Run the dungeon, check the daily dungeon shop, and review active event shops. Easy and hard modes can provide different slate portions, while shops may help complete a missing piece.

Q: How many S-rank pets are needed for SS fusion?

The demonstrated fusion screen requires six eligible S-rank pets. Epic, legendary, and mythical S-rank pets can qualify, while gray dummy pets may not be accepted.

Q: Why does my evolved S-rank monster not appear in the fusion list?

An already evolved monster may be excluded from the SS fusion list. A possible route is using a reversion potion, completing the SS fusion, and evolving the monster again.
