Nature's Protection 2014

Your surrounding natural environment accommodates your movement while creating obstacles to protect you in a 10-foot radius. Until the spell ends, the aura moves with you, centered on you. The area within the aura provides three-quarters cover, and is difficult terrain for creatures other than you.

As a bonus action (or as a reaction to a creature entering the aura), you can cause the elements to powerfully surge away from you. Large or smaller creatures within the aura must make a Strength saving throw. On a success, a creature is pushed out of the aura’s area to the nearest unoccupied space. On a failure, the creature also falls prone.
