Harder Dense Mining

Slows stone mining depending on neighbor block count to make cave exploring more viable. Also has global mining speed modifier.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

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.

A simple mod that slows stone and deepslate mining depending on the amount of rock blocks around the block you are trying to mine to balance straght-down mining vs cave exploring.

Mining speed goes from 100% to 15% depending on rock count around one you are mining.
You can whitelist more blocks, change slowness multiplier and global mining speed in the config file.
