As an action, you pull the breath from a creature that you can touch or see within 10 meters. The creature must make a Fortitude saving throw. If the creature doesn’t breathe, the spell has no effect on it.
On a failure, it loses 2d10 health and is deafened, can’t speak, and can’t use breath weapons until the end of its next turn.
On a critical failure, it loses twice as much health.
On a success, it loses half as much health.
On a critical success, it loses no health.
You can increase the health lost by 3d10 for each additional mana expended.
