As an action, a creature that can hear that you can touch or see within 10 meters must make a Will saving throw.
On a failed save, you whisper a discordant melody that only the creature can hear, wracking it with terrible pain as it takes 3d10 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, it takes half as much damage and doesn’t move away.
You can increase the damage by 4d10 for each additional mana or psi expended.
