Components and Foci: The Materials of Magic

This supplement examines why arcane spells use material components, the principles governing their effects, and whether those components can be changed. It details the components used in common spells and provides an extensive treatment of standard arcane magic. Rules and guidance allow mages to devise alternative components and recipes that may increase a spell’s potency, while introducing the risk of magical imbalance and harmful consequences.
