Oracle: Mystery

An oracle wields divine power, but not from a single divine being. This power could come from a potent concept or ideal, the attention of multiple divine entities whose areas of concern all touch on that subject, or a direct and dangerous conduit to raw divine power.

Choose the mystery that empowers your magic. Your mystery grants you additional spells, and special focus spells called revelation spells. Your mystery also gives you a unique cursebound ability that lets you draw upon the divine, as well as dictating the effects of the oracular curse that falls upon you when you touch too much of this power.

Focus spells are automatically heightened to half your level rounded up, much like cantrips. Focus spells don't require spell slots, and you can't cast them using spell slots. Certain feats give you more focus spells.

The maximum Focus Points your focus pool can hold is equal to the number of focus spells you have, but it can never be more than 3 points.

You learn a revelation spell at 1st level and start with a focus pool of 1 Focus Point. This spell is an initial revelation spell determined by your mystery.
