School of Evocation: A Compendium of Evocation Magic is a d20 system rules supplement expanding the magical school in the subtitle. Chapters cover new subschools of evocation, an evoker core class, eight new prestige classes, feats, a list of evocations, new spells, equipment, and magic items.

From the back cover:

Beyond fireball.

Continuing a new series of books from Fantasy Flight Games, School of Evocation contains everything you need to give evocation magic the diversity it deserves.

Featuring more than 60 new spells including the city-leveling power of tempest, School of Evocation gives evokers their own domains to study in the form of "disciplines." Evokers can now master fire, ice, energy constructs, and five other disciplines in their quest for limitless power. Best of all, the visual guide to evocatiosn shows at a glance what type of damage each spell inflicts.

This book also contains 8 new prestige classes and a new core class—the devoted evoker. In addition, it contains dozens of new items—both magical and mundane—to delight players. Whether you're customizing your very own evoker's robe or puzzling out how to best use the enigmatic corrosive globe, you'll gain a new understanding of the true power of evocation.
