How to use:
The Journal of Alchemy can be crafted with a book, a stick, and a bottle, and can serve as your guide through the rest of the mod.
Each page is written in the style of alchemist’s notes from one of three different narrators.
Some of the mod’s content is described in the form of “Objects of Study”, which require you to run some kind of experiment before their secrets are revealed, but essential mechanics are outright explained.
JEI integration for all items is present.
