You weaken the bonds that hold earth and stone together. If your target has Hardness, you can affect one contiguous object, up to a 5-foot cube, or one creature, decreasing the Hardness by 5, to a minimum of 0. If the target lacks Hardness, it gains weakness 3 to physical damage. A target with a Fortitude modifier can attempt a Fortitude saving throw, negating the effect on a success.
