- This page is about the Philosopher's Stone added by ProjectE. For other uses, see .
The fabled alchemical catalyst that allows the transmutation of base metals into gold, the Philosopher's Stone is arguably the foundation of ProjectE. There are three basic uses. Firstly, as a component in the construction of items like the Transmutation Table. Secondly, as a transmutation tool, for example turning iron into gold or vice versa. Finally, as a portable crafting table, capable of smelting items. Thirdly, the R button will transform mobs into other mobs.
As the Philosopher's Stone is used in such a large number of recipes, the use of a recipe manager such as JEI or NEI is strongly recommended.
