Earthwave

You make two pillars of earth erupt in a violent burst from the ground, hitting two creatures you can see within range. The targeted creatures need to make a Dexterity saving throw, receiving 2d6 bludgeoning damage on a failure and falling prone, or only receiving half damage on a success. When all spell effects take place, the pillars return to ground level.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 and you can target an additional creature for each slot level above 1st.
