PotionControl

On first startup the mod generates JSON files for each potion and potion type it finds. These files are created in an inactive state, so no change applies until a file is moved into the active folder. Once active, a file can set a potion's display name and description, whether it counts as a good or bad effect, its liquid color for the tooltip, which curative items remove it, its attribute modifiers, and its maximum amplifier and duration. Instant and repeating behavior, the repeating period, and how stacking with an existing effect is resolved can be set as well, including whether a longer duration wins over a higher amplifier.

The mod can also unregister specific potions and potion types, and it lists the effects with their amplifiers and durations that remain brewable. A global option changes the brewing time for all potions. The author built it on the same mixin backbone as Enchantment Control, so its approach to editing vanilla and custom potions matches that mod. It requires FermiumBooter and BetterConfig, and it is open source under the MIT License. Files are published for 1.12.2, with 1.1.1 as the latest Forge file, released 2026-09-25.
