On a failed save, a creature loses 2d12 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 loses half as much health.
This has no effect on creatures that do not breathe.
You can increase the health lost by 1d12 for each additional catalyst expended.
