As an action, you remove all the oxygen in a sphere centered on a point you choose within 36 meters. Each creature in the sphere must make a Fortitude saving throw.

On a failed save, a creature takes 7d6 necrotic damage and cannot speak or use breath weapons until the end of your next turn as a visible line of swirling air leaves the creature’s mouth.

On a successful save, a creature takes half as much damage.

The spell has no effect on creatures that do not breathe.

Augment

You can increase the damage by 2d6 for each additional mana or psi expended.
