Banshee Scream

Imitating the tortured undead, you scream with all your might, causing those around you to fall in agony. 

All creatures within range must make a Constitution saving throw or take 2d6 Necrotic + 2d8 Thunder damage on a failed save or half as much on a successful one.  In addition, all creatures within 10 ft. that fail the saving throw fall prone for 1 round and are deafened for 1 minute. 

Casting at higher levels:  The thunder damage increases by 1d8 per spell slot above 3rd.
