Pill Refinement

The Pill Cauldron is the central location where pills are made. Two input slots take a dust first and a binder second, and the cauldron has ten input slots in total. Dust falls into two groups: the base group covers the everyday materials, while the modded group adds cultivation-style ingredients such as wheat, cherry, poison, six poisons, yin yang and true death. The final stage takes the longest, and the items' lore holds the dust together inside the finished pill.

The mod is inspired by cultivation stories from manhua and manhwa, and its pills draw on real medicinal methods, some of which are still used today. Binders include wheat, honeycomb, slime ball, snowball, turtle scute and phantom membrane. Manuals are crafted through progress: crafting earlier pills makes the manual for the next one available, and REI compatibility ignores the manuals.

Pill Refinement is a Fabric mod for 1.21 – 1.21.2, published in three release versions. It runs on the client and the server, so the server and every player need it. The license is the MIT License, and the project is not open source. The latest Fabric file is 0.7.1 for 1.21.2, released as an alpha build on 2026-06-18.
