As an action, a ravine of gravitational force shoots out in a line. Each creature in the area must make a Reflex saving throw.

On a failed save, a creature takes 2d6 concussion damage, is slowed 1 until the end of its next turn, and if it is Medium or smaller it is pulled up to 4.5 meters toward the center of the area.

On a successful save, a creature takes half as much damage and isn’t pulled.

Augment

You can increase the damage by 2d6 and affect a creature of a larger size for each additional mana or psi expended.
