The Alchemy Engine is a Science structure item in-game. It costs 6 Gold Nuggets, 4 Boards and 2 Cut Stones to craft. The Alchemy Engine is used to prototype items, effectively unlocking the items so that the player can craft them at any time with the materials required. Additionally, players' Sanity will increase by 15 if you prototype an object on the Alchemy Engine.
The Science Machine is used to unlock tier 1 items, and the Alchemy Engine is used to unlock tier 1 and tier 2 items, making the Alchemy Engine the higher level Prototyping machine. (In addition, the Shadow Manipulator is utilized to unlock tier 3 items.)
A Science Machine is needed to prototype an Alchemy Engine.
