Fortune Telling Domain

A Fortune Telling Cleric is one that worships the threads of fate itself. Though it isn't that uncommon for them to venerate gods associated with Fate and Luck. Such as Beshaba or Tymora.

Their power's origins are often unknown even to them and can't pinpoint when their powers first manifested, for the soul of a Fortune Teller is something that is always changing and flowing, maybe they were blessed by a god or perhaps they themselves can spin the wheel that threads fate.

Whatever the case they all revere the cards as tools as much as magical conduits.
