Cosmic Winds

As you thrust you hand forward towards an enemy a tendrils of cosmic energy busts forth from your hand like cold gusts of wind resembling the nights sky. You can use this spell as a deterrent against enemy attackers. When you use this spell as a reaction on a target that has just hit you and is with in 5 feet they must succeed a CON saving throw. On a failed save the target takes 2d8 Force damage and is pushed back 15 feet in a straight line, they are then unable to use their movement until the start of their next turn. On a successful save the enemy takes half damage and is not moved.
