Blindsense (Ex): The thin feather at the base of a half-farspawn dragonhawk's beak is extremely sensitive to vibration. Combined with the bird's excellent sense of hearing, this gives a half-spawned dragonhawk blindsense to a range of 60 feet.

Creature native to the Material Plane take a -1 morale penalty on attack rolls against the half-farspawn dragonhawk in its amorphous form.
