As an action, you can create this vial of orange and green liquid. 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 Reflex saving throw.
On a failed save, a creature takes 5d4 acid damage immediately and additional acid damage equal to half the amount of acid damage dealt at the end of its next turn.
On a successful save, it takes half as much damage and no damage at the end of its next turn.
You can increase the damage by 3d4 for each additional catalyst expended.
