Tahn'Na's Retribution (Get Clapped)

You clap your hands about each side of a persons face, releasing a thunderous boom and a shock of energy.   Make a melee spell attack, on a hit the target takes 4d8 thunder and 4d8 lightning damage, and the target must make a Constitution saving throw or be deafened.  When you cast this spell at higher levels it deals 1d8 extra of either lightning or thunder damage (your choice.)
