Secrets of the Planes: Planar Magic
Put the power of the planes in the palm of your hand! Planar Magic introduces the planar mage, a new 20-level core class whose spellcasting abilities are determined by the plane to which he has chosen to attune himself. Use the planar mage alongside your wizards and sorcerers, or even in place of them. In addition to the class and several supplementary feats, Planar Magic also includes no fewer than 60 new spells.
Although designed primarily with the planar mage in mind, these spells are 100% functional even in campaigns that do not focus on or even employ this new class. If you want your magics to have a more planar feel, or are simply looking for something new to offer your sorcerer or wizard, this is the place to look!
