Craftable Potion Combinations

Crafting a potion mix through the crafting grid merges effects into one item, which saves inventory space that a fixed-size inventory otherwise uses up. One combined potion can carry Water Breathing and Night Vision together, where separate potions would need three slots. Combining takes the place of carrying each potion on its own, and the result is consumed like any other potion when drunk.

The mod is server-side only, so players join a server that runs it without installing anything. It is published for Fabric across nine release versions, 1.19 – 1.21.11, and is open source under the Mozilla Public License 2.0.
