Requirements You currently have a fly Speed.

Like the fastest of predatory birds, you soar toward your prey at great speeds. Fly twice. At any point during this movement, you can make a Strike against one enemy within reach or within the first range increment of a ranged weapon. That enemy is Off-Guard against the Strike if you're attacking them from above.
