As an action, you can create this vial of yellow and pink swirling gas. As an action, a creature can throw the vial at a point within 9 meters, shattering it on impact. Each creature in a sphere centered on that point must make a Fortitude saving throw against poison.
On a failed save, a creature takes 3d8 poison damage and is poisoned and confused for the duration.
On a successful save, a creature takes half as much damage and isn’t poisoned and confused.
A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
You can increase the damage by 1d8 for each additional catalyst expended.
