As two actions, you can create this vial of yellow and pink swirling gas. As an action, a creature can throw the vial at a point within 5 meters, shattering it on impact. Each creature in a sphere centered on that point must make a Fortitude saving throw.

On a failure, it takes 2d10 poison damage and is poisoned and confused until the end of its next turn.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

Augment
You can augment this concoction with the following options, expending catalysts for each option.
  • You can increase the damage by 1d10 for each additional catalyst expended.

  • You can expend 1 additional catalyst so the concoction is unstable and the duration changes to 1 minute/catalyst, unstable and a creature is poisoned and confused for the duration. The damage is reduced to 2d6 and additional augments to the damage increase the damage by 1d6 for each additional mana expended, instead of the normal increase. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
