About this Mod
Crim's Alchemy
Crim's Alchemy is a data driven modular potion brewing mod for Minecraft Forge 1.20.1. It adds a special Alchemical Cauldron that lets you add multiple effects onto a single potion. JEI is recommended.
The Alchemical Cauldron
The Alchemical Cauldron block is where all alchemy occurs in the mod. It requires a heat source, such as fire or a magma block, to function along with water. It starts with a capacity of 1, meaning 1 effect may be added. Adding netherwart or netherwart blocks adds additional capacity. More ingredients, amplifiers, or duration modifiers use up capacity.
To get the cauldron, the anointing paste item is needed. You can craft it using two mushrooms, seeds, and bone meal or their nether variants. Then, click on a vanilla cauldron using the paste, or craft the vanilla cauldron with the paste.
Data Driven
This mod supports data packs for adding more recipes. Explanation in source code.
