Capabilities
Theury allows it's users to call upon gods, spirits, and demons to do things and preform miracles for them. This often allows them to be more powerful than magicians who's powers are their own, but are relient on the beings that aid them.

Limits

 * Gods, demons, and spirits don't just give out power. They'll demand something in return. Perhaps your soul, service, personal energy, sacrifices, or a dozen other things.
 * Some areas may be beyond the entity's authority: for example, demonic magic probably wouldn't work in a church.
 * The entity may have a limited ammount of power, and still be bound by laws other magic is.
