Be sure to check out the mod Ars Magica: Legacy (CurseForge / Modrinth), which is where the project originated!
Potion Bundles makes it possible to tie three potions together with a string (configurable in the newer versions) as a shapeless crafting recipe. On consumption of one usage, you get a bottle back, as well as the string used to tie them together (configurable) on the last use. This was originally a feature of Ars Magica 2 by Mithion, but when we started porting it to newer versions, we liked it so much that we decided to release it as a standalone mod. Bundles work with every potion registered, including modded ones!
This is a Forge Mod, we do NOT support Fabric or other mod loaders at the moment and will not backport to older versions. We will however port to newer versions as soon as we find the time.
Feel free to use the mod in your modpack (just don't require money to play it), or join our Discord server! https://discord.gg/GcFqXwX
