You jump out of the way of dangerous effects.
You must move to the nearest space you can see outside of the affected area. The DC for this Acrobatics check is equal to the number of feet you must move to escape the area, and you can’t travel farther than your normal movement. If you use this feat, you are staggered on your next turn. This movement doesn’t provoke attacks of opportunity from creatures in the area of the effect you are escaping.
