Fear (Su): By leering and growling, a Fearow can frighten creatures which view or hear it. All creatures within a short ranged cone (25 feet plus 5 feet per two hit dice long and wide) must make a three consecutive Will saves (DC 10 + half HD + Charisma modifier), becoming shaken for each save failed. Remember that shaken creatures who become shaken again become frightened, and then panicked. A creature which passes all three saves is immune to the Fear ability of that Fearow for 1 hour, and the fear lasts for 1 minute per hit die of the Fearow. The sample Fearow has a Fear DC of 24.
