Crystalmancy: Powers of the Gems
This fantasy roleplaying supplement introduces crystalmancy, a form of arcane magic based on the use of gems and crystals. It presents a new core class and prestige class, along with feats, spells, and magic items for crystalmancers and other spellcasters. The supplement also details the Plane of Crystal, its locations and inhabitants, the Crystal Keepers organization, and five crystal lords. New creatures include crystal golems, gem bones, gem dragons, and the crystalline berylis race. The material can be used to add crystalmancers to a campaign or to introduce remnants of their magic into an existing setting.
