Disturbing Voices

You cause a creature to hear whispers recalling it's greatest guilts and traumas, wracking it with terrible pain. The target must make a Wisdom saving throw. On a failed save, it takes 3d6 psychic damage and must immediately use its reaction, if available, to coil in place from the memories (effectively going prone). On a successful save, the target takes half as much damage and doesn’t have to coil.

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.
