Erratic Rhythm

You leap into a musical performance of a strange and ever-changing rhythm, weaving the notes with subtle magic as you target up to four creatures within 60 ft. If the targets can hear you, they must succeed on a Wisdom saving throw or take 2d6 psychic damage and have their movement speed reduced to half the normal amount for the duration. On each of your turns for the duration, you can use your action to deal 2d6 psychic damage to targets that failed their saving throw.

When you cast this spell using a spell slot of 2nd level or higher, you can choose one additional target and the damage increases by 1d6 for each slot level above 1st.
