Wakos use vocal calls to communicate and can relay exact location and even basic emotions within 60 feet (120 feet underground). When three or more wakos are present, all non-wakos take 7 (2d6) thunder damage each round at the beginning of their turn, or half as much on a successful DC 11 Constitution saving throw. Creatures failing their save are deafened for 1 minute, though they can attempt a new save each round to end this effect and once they save they cannot be deafened by wakos for 1 hour. if a wako matriarch is present the damage dealt by this ability increases to 10 (3d6) and the save DC is 13.
