Armybreaker Dirge

Hostile creatures of your choice in the emanation that can hear you must make a WIS save. On a failed save, a creature is frightened for the duration, subtracts 1d10 from the first attack roll or saving throw it makes on each of its turns, and must make concentration saves with disadvantage. On a success, the creature is not frightened but subtracts 1d10 from its next attack roll before the end of its next turn.
