As an action, you can create this bomb. As an action, a creature can throw this bomb at a point within 9 meters, where it explodes on impact. Each creature in a sphere centered on that point must make a Fortitude saving throw.
On a failed save, a creature takes 3d8 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, it takes half as much damage.
This has no effect on creatures that do not breathe.
You can increase the damage by 2d8 for each additional catalyst expended.
