Night Howl (3.5e Maneuver)

HOOOOOOOOOOOW-HOOOOOOOOOOOWWWLLLLLLL!!!!

Your release a baleful howl which triggers an instinctive fear of wild beasts in others. Creatures who fail their save become frightened for 1 round per level. If the Will save succeeds, the creature is shaken for 1 round.

This is a supernatural maneuver.
