Gravel Pelt
This spell is a part of the Dust Devil spell chain and can be found in the Dust Devil rune stone.
Gravel Pelt does exactly what the name implies, it pelts the enemy with small stones. The magic launches four stones at the target. The magic pummels these stones into the target doing 2d12 magical damage and then the stones fall to the ground, as ordinary as any other stone on the side of a road.
