Eat Rocks!

You conjure hard stones which pummel your target. You must yell “Eat Rocks!” when casting. The target of your spell must make a Constitution saving throw or take 1d8 bludgeoning damage. Additionally, on a failed save, the first attack 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)
