Beastly Haymaker

You transmute a free hand into the visage of a beastly animal such as a bear or lion and attempt to strike a creature.

Make a melee spell attack. On a hit this spell deals 2d6 force damage and the creature must make a Dexterity saving throw or be grappled by the caster until the end the casters next turn. A creature grappled in this way may use its action to make a Strength (Athletics) or Dexterity (Acrobatics) skill check against the casters spell save DC. On a success, the creature frees itself.

For each level above 1st that this is cast the damage increases by 2d6 force damage.
