Master Skater

You’ve developed the skills necessary to move with quick burst of speed by skating on flat metal objects. You gain the following benefits:

• Create Skateboard. You can use your bonus action to prepare your shield or another medium flat object made of metal to skate with. After which when you would move normally, you can instead skate on the prepared object. (You do not gain the benefit of your shield if you have it prepared.) You may end your skating preparation prematurely with an action or bonus action.
  • Skating. While skating, once on each of your turn if you have moved at least 15ft in a straight line during your movement, you may move an additional 20ft with the same movement, if you stopped mid way or change direction, this bonus is annulled until you moved another 15ft in a straight line again. You can move down ramps or on top of water, however if you enter difficult terrain while skating this way you immediately fall prone and drop your "skate board"/ shield 15ft away from you.
• Expert Skater. When you are moved against your will you may also use your reaction to prepare your shield to skate with.
