A Neoforge 1.21.1 Minecraft: Java Edition mod with the express purpose of merging potions together.
This mod adds one new block entity: the Merger, crafted with one Merger Core and two Merger Tanks; and a new tool, the Claved Retort. Placing two potions and blaze powder into the Merger will output a Mundane Potion (of whichever kind the top potion was: e.g. if the top potion was a Splash potion the output potion will be a Splash potion no matter what type the bottom potion was) with the effects of both potions.
The Retort is used to inject and extract effects directly from mobs. It requires glass bottles (and water, depending on the settings) to extract, and an item to inject in the offhand to inject. NOTE THAT, AS OF WRITING, ANY ITEM WORKS; INCLUDING ITEMS THAT GIVE NO EFFECT!
Limits to how many effects the output potion can have, as well as their strength, are present in settings; the output potion will turn into coal if these limits (by default 3 levels and 3 effects) are exceeded.
