Wolkaft Discordant Array

You swing your whistle sticks and a discordant melody sounds. It affects creatures of your choice within range that can hear, wracking them with terrible pain. Each 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 move as far as its speed allows away from you. The creature doesn’t move into obviously dangerous ground, such as a fire or a pit. On a successful save, the target takes half as much damage and doesn’t have to move away. A deafened creature automatically succeeds on the save.
