Wind strike combination

The power of the winds launch you towards your enemies, attacking them with all the force you can muster. As an action, you launch yourself up to 40 feet in a straight line, Attacking on landing with your weapon as normal but also once more for every 10 feet you move while launched; Though every strike after the first only uses a d4 for your damage die. At higher levels, your subsequent attacks use a d6 as your damage die instead of a d4.
