Dazzling Whip

Your weapon becomes a long beauutiful whip that you lash out with towards a creature in range. Make a melee attack against the target. If the attack hits, the creature takes 1d6 piercing damage, and it has disadvantage on the next weapon attack roll it makes before the end of its next turn.

The spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
