Formulae are alchemical recipes for creating potions, oils and bombs. Each formula lists the required ingredients and describes the type of base necessary to create the mixture. These recipes are typically acquired by reading scrolls, but some may be acquired through word of mouth, i.e. by speaking with certain NPCs. In addition, they can be learned by alchemical experimentation during meditation and subsequent usage with exception of fisstech which requires only experimentation.
