  The Arcanas teach you a set series of spells. This Basic Arcana covers the first of them, and the Intermediate and Advanced Arcanas cover more.<~><~>  These are only a small part of what exists. There are thousands of other spells spread across the world. You can find them by exploring, searching ruins and structures, making spell notes, finding scattered pages, and defeating certain creatures.<~><~>  You can also make your own spells at the Spellforge, where you combine magic into a custom spell that no one else has.
