Dissonant Melody

You play a discordant tune, harming the creatures around you. Creatures within 30ft. of you must make a wisdom saving throw. On a failed save, the creature takes 10d4 psychic damage and has disadvantage on any attack rolls until the end of its next turn. On a successful save, the creature takes half as much damage and suffers no disadvantage. A deafened creature automatically succeeds on the save.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d4 for each slot level above 3rd.
