Wall Jump

Description
You are a learned practitioner of the ages old skill of getting from one place to another as fast as possible. As part of that knowledge, you know how to gain height without needing to run up a staircase or ride a vehicle or an elevator. You can leap from one wall to another, back and forth until you reach the top - just don't exhaust yourself before you get there, or something bad could happen.

Effects
When you use Wall Jump, you spend 2 Stamina. You also spend 1 AP if you use Wall Jump while in combat. You make a Jump roll during which you may treat vertical surfaces as valid landing zones. You can use Wall Jump repeatedly in order to gain height so long as the surfaces you are jumping between are close enough together.

You must continue Wall Jumping as long as you are "standing" on a vertical surface. If you pause for more than 2 seconds or make another action, you immediately lose your footing and fall.
