Reaver's Howl (1/Day). Every enemy within 40 ft. of the Bloodreaver must succeed on a DC15 Constitution saving throw or become deafened for 1 minute; while deafened creature's attacks against the orc are at disadvantage. Any allies of the orc within 40 ft. gain advantage on all attacks made against deafened creatures for 1 minute. A creature can repeat the saving throw at beginning of each of its turns, ending the effect on itself on a success. Once the effect has been removed, the creature is immune to Reaver's Howl for 24 hours.
