Terran Fist

You churn the earth from the surrounding area molding it to form a fist over top yours. The stone gauntlet remains there for the duration. During this time if you attempt a grapple check you can use your spell casting modifier in place of your strength modifier. While grappling with the earth covered hand, that hand is occupied and cannot be used for any other means.

You can also attack with the fist, although doing so ends the spell. When you cast this spell, or as an action on a later turn, you can strike a near by creature or one at a distance. If striking a near by creature, make a melee spell attack against one creature within 5 feet. On a hit, the target takes 1d10 bludgeoning damage. If striking a distant creature, make a ranged spell attack against one creature within 30 feet. On a hit, the target takes 1d8 bludgeoning damage. After you make the attack, the fist crumbles.

The spell’s damage increases by 1d10/1d8 when you reach 5th level (2d10/2d8), 11th level (3d10/3d8), and 17th level (4d10/4d8).
