DatapacksJava
Metals: A Progression Overhaul
Java data pack listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Metals
Warning this makes minecraft significanly harder
This is a decent size progression overhaul. It is designed to increase the time it takes to get max gear from 2 hours to about 7-10 hours but with becoming to grindy.
It does this by changing
- Mob and Player, health and damage.
- Crafting Costs, reqiring different roods for tools.
- Block Drops, adding a chance for copper to drop from diorite, granite and andesite.
This should be compatable with most mods and datapacks that don't overide tool and armor stats and recipes.
