Cataclysmic is a RPG Styled modpack with new bosses, items and dimensions. Play, and level up how you like. Encouraged to play with friends on a server for the full experience. Inspired by Terraria's Calamity.
The Modpack is in Early Development FOR FUN, the modpack is ready functionally and works well, its more so in need of a datapack clean up to remove any inconstistencies. (Example, water based origins will say they can only breath underwater when they can breath air in this modpack) This modpack has been tested on low ram (4gb), and low specs and runs pretty okay. If your PC can run Minecraft on Lunar Client with good FPS and Performance, you may be able to run this modpack. I created this Modpack with low performance in mind.
Tweaks -
Origins ReSized - A Datapacked I used with data from Origin Statures to adjust the sizes of multiple origins. There are now 3 main sizes and picking a class and either make you even smaller or bigger.
Origins & Water Specific Origins: All water based mobs using origins and it's "Gills" power were adjusted to be able to breathe on land but still breathe underwater. (Datapack by Stealth.exe on the origin discord server)
Origin Classes: Condensed, classes were combined because some seemed repetive or made more sense combined.
Twiligt Forest: Using Gamerules, forced progression is disabled. Once unlocked you can freely explore and fight in The Twilight Forest.
Combat Roll: Added Combat Bashing for fun
Terraria Inspired Inventory - Inventory and Chests can be organized easier
Paperdoll - Some Origins have custom Player Appearences, this lets players view their model in first person
Better Third Person - Dropped Shoulder Surfing for BTP, this lets players play in 3rd Person smoothly as if they were playing like Kingdom Hearts.
All mods included were allowed to be used without permission needed, I will be crediting them when I have time to make a spreadsheet. No Permission is needed to backport, or forward this modpack. (I really wanted REPO Heads in this modpack but couldnt make a version that felt right so i went back to 1.20.1)

Frequently Asked Questions
Cataclysmic server crashes or won't start – what to do?
Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 8 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.
How much RAM does a Cataclysmic server really need?
Minimum 6 GB, recommended 8 GB for stable performance. per 5 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €12/month).
Can I add custom mods to Cataclysmic without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.20.1). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
Cataclysmic server lagging – performance tips
1) Increase RAM to 8 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
