Apothecary's Shop

The Apothecary's Shop is a structure from the Witchery mod. This structure spawns with villages, and serves as a house for the Apothecary. In here you can find a Cauldron with water, a flower pot with a cactus, and a chest hidden in the floor.

The Apothecary can sell/buy witchcraft ingredients, but everything they sell has another way of obtaining it, so it is not required to find a shop.
