Eldritch Grip

You reach out and grasp your enemy as otherworldly energy gathers in your hand. As your spell lashes out a blast of energy flows forth with the force of a sledgehammer. 

Make a melee spell attack, on a hit the target takes 1d10 force damage. The spell gains flat damage when you reach higher levels: +6 to damage at 5th level, +12 at 11th level and +18 at 17th level.
