Alchemy

During the prologue, the player character will acquire a cauldron that will allow her to perform alchemy from her home. The potions she creates can have a number of effects, and can be used on NPCs, sold at the market, used on herself, and more.

Alchemy Progression
As the player character performs alchemy and makes potions, she'll become more experienced and unlock new recipes, allowing her to make new potions. Potions can have a variety of powerful effects, and can be sold for a lot of money, so making potions can be extremely lucrative and help you overcome a variety of challenges.

Some potions can only be learned by finding their recipes in the world, from completing requests, or by learning them from certain characters.
