DatapacksJava
Effect Randomizer
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.
Effect Randomizer
This Data Pack recreates the SmallAnt Effect Randomizer Challenge!
It gives you a random effect (except for instant damage and instant health) for 60 seconds, every 20 seconds, from level 1-10.
There is a 20 second grace period upon spawning into the world.
Shout out to tjthings and Eulerian for also making a data pack like this.
