Slow Mining
I don't know my version or loader

Slow Mining
Overview
This datapack reduces the mining speed of players by 75% (minecraft:block_break_speed = 0.25).
Slow Mining makes the early game and late game of a world or server more challenging and fun.
Configuration
To configure how fast players break blocks, unzip the datapack, open the folder, and navigate to:
data/slowmining/function/tick.mcfunction
Open the file and edit the value on the 2nd line of code to customize the mining speed.
⚠️ IMPORTANT
If you want to disable or remove the datapack, run:
/function slowmining:disable,
otherwise the datapack will not disable properly.
