Earth Stomp

You stomp the ground, causing it to shake and flinging bits of earth and stone at nearby foes. Each creature within range other than you must make a Dexterity saving throw. On a failed saving throw, a creature takes 1d6 bludgeoning damage. The spell fails if the caster is not touching the ground when it is cast.

The spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
