Deafening Wealth

You take two condensed coins and clap them together. Each creature in a 20ft radius sphere centred on you must make a Constitution saving throw. A creature that is deaf or has no natural hearing is unaffected by this spell. A target takes 8d6 force damage on a failed save, or half as much damage on a successful one. 

After a failed save, a target is deafened for 1 minute. During that time, it has disadvantage on Perception checks and spells that have verbal components, as well as its Constitution saving throws to maintain concentration. The target can make a medicine check at the end of each of its turns, ending the effect on itself on a success.
