Fatebones

With the fatebones spell, a witch of void and air may attempt to scry a brief glimpse of the future. By casting it on a trophied hand and tearing out the knuckles thereof, she may enchant the bones, tossing them to discern the pattern in which they fall. The foresight granted by this spell amounts to a bonus to the mage's luck; more powerful castings will increase the bonus, provided the knuckles came from a sufficiently-powerful entity.
