Description: You harden the air around the target into jagged invisible blades that deal damage based on how fast the target moves. On its turn, the target takes 1d6 points of slashing damage if it moves at least 5 feet, plus 1d6 points of slashing damage for each additional 10 feet of movement. Movement that doesn't pass through air (such as burrowing, swimming, or teleportation) doesn't cause this damage. In areas of strong wind, the target takes damage on its turn, even if it doesn't move (1d8 points of slashing damage). This extra damage does not occur from instantaneous wind effects (such as gust of wind), only from wind effects that last at least 1 round. Each round the target may make a STR saving throw to attempt to push past the blades and avoid all damage that round.
