Abyssal Screech

Shrieks from an amalgamation of different languages, lashing out at anyone who are touched by your suffering. A burst of energy erupts from you. Each creature within a 15ft radius of you must make a constitution saving throw that beats a 15. On a failed save the creature must take 2d4 radiant damage and 2d4 necrotic damage and is deafened until the end of your next turn. On a success the creature takes half as much damage and is not deafened. 

At higher levels: when you cast this spell at a spell slot of 2nd or higher the necrotic and radiant damage are increased by 1d4 on each level above 1st.
