Dust in the Wind

You touch a creature that is dead. As though millennia have passed for the corpse, it is reduced to unfiltered sand whose color is determined by the target's alignment. If the creature was lawful, the sand is white. If it was chaotic, the sand is black. If it was neutral, the sand is a mix of both. You gain a number of unfiltered fistfuls of sand equal to the creature's challenge rating.
