Effect: If you are marked, that condition ends on you. You then fly 8 squares. This movement doesn't provoke opportunity attacks, and if you don't land at the end of the movement, you descend to the ground without taking falling damage. In addition, until the end of your next turn, you can shift 1 square as a free action whenever you are hit.
Elusive Wind is a 16th level Druid utility power. You can fly as a minor action if you are marked. [PrP:47]
