Cleric

The Mystic is a spellcaster who gets their power from summoning spirits and from adjuration, that is, from directly commanding Nature using names of power. The Mystic is roughly equivalent to the SRD class called "cleric" but is different in concept. The Mystic doesn't get their powers directly from a single god. They get them from the mystical teachings of a particular cult. The cults may be affiliated with a single god or they may be polytheistic in devotion. Cults are usually associated with a particular culture, so mystics from different cultures will have different powers.
