As an action, a creature that you can touch or see within 10 meters must make a Fortitude saving throw. This spell has no effect on creatures that do not breathe.
On a failed save, you pull the breath from the creature’s body as it loses 2d8 health and cannot speak or use breath weapons until the end of its next turn as a visible line of swirling air leaves the creature’s mouth.
On a successful save, it takes half as much damage.
You can increase the health lost by 4d8 for each additional mana expended.
