Cast Stone

You throw a single small rock at a target and it changes mid-flight to a giant boulder. Make a ranged spell attack. On a hit, the target takes 3d10 bludgeoning damage and the target must succeed on a Strength saving throw or be knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 2nd.
