Catch a Monster FAQ
What is the Roblox Catch a Monster tracker for?
The Roblox Catch a Monster tracker helps you plan monster fusions by showing how many more catches, monsters, and materials you need to reach a target rank.
How does the Roblox Catch a Monster fusion calculator work?
The calculator applies each configured Roblox Catch a Monster fusion rule in rank order, counts the monsters you already own, then estimates the extra catches and material costs needed for your selected target.
Why is S-rank the default target?
S-rank is the default target because SS-rank is created differently in Roblox Catch a Monster. You can still inspect other configured ranks when they are available.
Does the tracker save my inventory?
Yes. Your entered Roblox Catch a Monster monster and material counts are saved locally in your browser so the tracker can restore them when you return.
Where does the monster data come from?
Monster ranks, fusion costs, material names, icons, and evolution data are loaded from Tiny Epoch's remote configuration so the tracker can update without a full site redeploy.
