Custom Potions

by AshyBoxy

Custom Potions lets server owners define new potion recipes and effects through datapacks, without writing Java code.

FabricQuiltServer required, client optionalMIT LicenseOpen source1.20.6 – 1.21.4

What it does

Potion recipes are added by datapack, and the potion effects follow the same format as vanilla potions. Each potion can be given a color and a fallback name, and translations are read from a language JSON file. Splash and lingering variants fall back to defined effects when none are set. Custom Potions is server required and client optional, and it needs Fabric API. Files are published for Fabric and Quilt across six release versions, 1.20.6 – 1.21.4, under the MIT License, and the source code is open.

Key features

  1. Datapack potion recipes

    New potion recipes and effect lists are defined in datapacks, following the vanilla potion format.

  2. Fallback names and colors

    Each potion can set a fallback name and an optional color, with splash and lingering variants covered by fallbacks.

  3. Language file translations

    Potion names are translated through a language JSON file, so the text can be localized like other game strings.
