Non-baykoks within 30 feet who can hear it must make a DC 13 Wisdom saving throw. On a failed saving throw, a creature is frightened for 1 minute, and incapacitated as long as it is frightened. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to that baykok's Dread Howl for the next 24 hours.
