Deep Magic

Deep Magic is a form of magic that that taps into the very elemental makeup of the planes. It exists in a strange place between arcane and divine magic, and for all but the most powerful beings, impossible to wield without centuries of cultivation. Deep Magic is most commonly encountered in conjunction with objects or wards that require great strength to maintain long-term effect. For example, Pelor's Eye, kept in Stonefast Anchory, combats the Mistveil curse, and both of these things required Deep Magic to be cast.
