As an action, a ravine of gravitational force shoots out in a line. Each creature in a line must make a Reflex saving throw.
On a failed save, the creature takes 2d10 concussion damage, is slowed 1 until the start of your next turn, and if it is Large or smaller it is pulled up to 6 meters toward the center of the line.
On a successful save, the creature takes half as much damage and isn’t pulled.
You can increase the damage by 2d10 and affect a creature of a larger size for each additional mana or psi expended.
