Whirlpool of Doom

This terrible spell turns earth or silt into a swirling sea of rock and earth. Anyone standing in the area must make a save vs. spell. Failure indicates that they have been sucked into the center of the whirlpool and must begin to make Swimming proficiency checks at a +3 penalty. 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 proficiency check means the individual begins to drown.
