Howl (Recharge 5-6)

The vanara releases a sonorous howl in a 15-foot cone. Each creature in that area must make a DC 13 Constitution saving throw. On a failure, a creature takes 18 (4d8) thunder damage and is deafened for 1 minute. On a success, the creature takes half the damage and isn't deafened.
