Which build do you need?

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.

RainBeThunder is a simple mod that turns your rain into thunder 100% of the time (as is tested)! This is the vanilla thunder so all mods and vanilla mechanics should work with this mod!
