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.

Requires Ancient Aether

You may adjust the volume of the music in the mod via the "Jukebox/Note Blocks" slider in Options > "Music & Sounds" in the menu in-game.

Run the command /trigger aabmm.mutatedaechorplant_theme.toggle to toggle whether the boss theme should play or not.

Be sure to run the command /function ancient_aether_boss_music_mod:admin/uninstall before uninstalling the mod if you've had enough of it.
