Severe

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.

Mod loader

Minecraft version

⬇ Download for 1.21.2–1.21.8 · Data pack⬇ Download for 1.21.1 · Data pack⬇ Download for 1.21.2–1.21.8 · Fabric⬇ Download for 1.21.1 · Fabric⬇ Download for 1.21.2–1.21.8 · Forge⬇ Download for 1.21.1 · Forge⬇ Download for 1.21.2–1.21.8 · NeoForge⬇ Download for 1.21.1 · NeoForge⬇ Download for 1.21.2–1.21.8 · Quilt⬇ Download for 1.21.1 · Quilt
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.

NightML's Severe V.3.0.0

Have you ever been playing in your Minecraft world and thought it was a little bland? Well, if that is true, then this may be the data pack for you!

This data pack makes it to where a player will be randomly assigned an effect every 20 seconds - that is either severely positive or severely negative.

Created by NightML, aka NightMareLore.
