About this Mod

Given all other known Aether bosses out there have been assigned their own battle tracks, I figured why not drag the only outlier to this trend into the club?

There are also plans for this mod's compatibility to extend to any other Aether bosses that lack their own music, to which the mod will likely be rebranded as something else when that comes to pass.

͏

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/data pack if you've had enough of it.
