Abyssal Whispers

You utter maddening whispers from the abyss that disturb a creature's mind. 

Choose one creature you can see within range. The target must succeed on a Wisdom saving throw or take 1d6 psychic damage and become frightened for the duration. While frightened, the target takes additional 1d6 psychic damage at the start of each of its turns. If the creature ends its turn within 5 feet of you, it takes an additional 1d4 psychic damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
