Gravitic Fling

You grab your target with the power of your mind and repeatedly smash it into the ground, the ceiling, walls, or nearby objects. The target makes a Strength saving throw. On a failure the target takes 10d8 bludgeoning, piercing, or slashing (your choice) damage and is knocked prone. On a successful saving throw, the target takes half damage and is not knocked prone.

Surge. You can spend +1 psionic point per creature to affect up to 4 targets; +2 psionic points to affect all creatures of your choice within a 30-foot diameter area [requires power rating V].
