Eat Rocks!

You conjure hard stones which pummel your target. The target of your spell must succeed on a Constitution saving throw or take 1d8 bludgeoning damage. Additionally, on a failed save, the first attack roll made against the target before the end of its next turn has advantage. This spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).

VERBAL COMPONENTS
Just yell “Eat Rocks!” when cast.
