Whirlpool of Doom

''The ground collapses, drawing desperate creatures into a whirlpool of rock and sand. Those disappearing in the vortex will slowly suffocate to death.''

This spell turns earth or sand into a swirling sea of rock and earth. Anyone standing in the area must make a Reflex save. Failure indicates that they have been sucked into the center of the whirlpool and must make a Swim check (DC 20) each round. Creatures that make three successful checks in a row are able to make their way to the edge of the pool and pull themselves free. Failing a single skill check means that the creature is pulled below the surface (and must hold its breath) until it succeeds at a Swim check. Failing two Swim checks in a row means that the character has been pulled 1d6x5 feet under the earth.
