You slam your weapon into the ground and seismic energy erupts from you in an aura with a 30-foot radius. Until the spell ends, the aura moves with you, centered on you. The area inside the aura is difficult terrain to everyone except you.
When the aura appears, each creature of your choice that is within the aura's area must succeed on a Dexterity saving throw or be knocked prone. Each creature of your choice that starts their turn in the aura must also make the same Dexterity saving throw.
