Wave of Screaming Darkness

By clapping your hands together and screaming, you send a wave of screaming darkness forward in a 15-feet wide and long cone. All creatures within the cone must make a Wisdom saving throw, suffering 4d6 psychic damage. Succeeding the saving throw causes only half damage.

At Higher Level. Increases the damage dice by 1d6 for each spell slot use above 2nd level.
