Cry of the Banshee

Imitating the tortured undead, you scream with all your might, causing those around you to fall in agony, reeling and clutching their heads in pain. All creatures within range must make a Constitution saving throw or take 3d8 Necrotic & 3d8 Thunder damage on a failed save or half as much on a successful one. In addition, all creatures that failed the saving throw are stunned and deafened for 1 minute. Any creature that fails the saving throw may repeat the save at the end of their turn, ending the effect on a success.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the thunder and necrotic damage increases by 1d8 each for each slot level above 4th.
