Fly This unit can move over, and pivot while over, anything, as long as its entire move ends clear of any units or Blocking Terrain. It does not suffer Hindered Charges for moving over Difficult Terrain or Obstacles, unless it ends the move within or touching them. While Disordered, it cannot use Fly. If a unit with Fly has Nimble, then that is also lost while Disordered.
Nimble This unit can make a single extra pivot of up to 90 degrees during any Movement order except a Halt. When Disordered by a unit in Melee with Phalanx or Ensnare, it loses Nimble until the end of its following Turn.
Pathfinder This unit suffers no movement penalties for Difficult Terrain, treating it as Open Terrain in the Movement Phase. It is not Hindered for Charging through, or ending its Charge on, Difficult Terrain. Obstacles still Hinder.
