Blistering Dash

You dash in a straight line with a range of your remaining movement speed x2. Everything in a 5 ft radius along the line, has to make a dexterity save. On a failed save the character takes 8d6 lightning damage and, if they are wearing metal armor, they are paralyzed for one round. On a successful save they take half damage unless they are wearing metal armor in which they automatically fail the saving throw.
