Freerunner's Profiency

You are a master in the art of freerunning. You gain the following benefits:

• Your speed increases by 10 feet.
• When you use the Dash action, difficult terrain doesn't cost you extra movement on that turn.
• When you make a melee attack against a creature, you don't provoke opportunity attacks from that creature for the rest of the turn, whether you hit or not.
• When you move more than 20 feet in a straight line and there is a wall perpendicular to the direction you were running in, you may initiate a 'wall run' as an action. This allows you to move along the wall's surface a distance equal to the following: ((height in feet / 2) * 10) + 2 for every 5 feet you moved in a straight line before initiating the wall run.
