You foretell a creature, object, or place's future or learn a secret of the target in a cryptic prophecy of the DM's creation. You speak the prophecy in a booming voice that can be heard from 5 miles away. A creature knows that its fate has been foretold but it does not know the details of the prophecy. You may not cast this spell for 1d100 + 10 years after the original cast. If you cast this spell a second time add 20 to the dice roll if you do it a third time add 30 to the dice roll etc.

This spell can be used as a plot device for example finding the BBEGs weakness or knowing how to destroy an evil artifact.
