Eldritch Scream

You release an exceptionally loud, incomprehensible noise. any creature within hearing distance can hear the sound, but only creatures in a 60 ft. emanation are effected by it. every creature that isn't deafened and is able to hear must make a constitution saving throw (15 to pass), on a failed save, the victim takes 8d8 thunder damage, gains the deafened condition, and has disadvantage on checks made until the start of your next turn. on a successful save, the victim only takes half damage, isn't deafened, and only gets disadvantage on its next check. creatures within 30ft. have disadvantage on the saving throw, and creatures within 10 ft. automatically fail, and take an additional d8 damage, allies have advantage on the check, and you can give them a warning to cover their ears, preventing the effects.
