As an action, all nonmagical food and drink within a sphere centered on a point of your choice within 9 meters is putrefied. If a creature consumes the putrefied food or water it must make a Fortitude saving throw against poison.
On a failed save, a creature takes 3d6 poison damage and is poisoned for 1 hour.
On a successful save, a target takes half as much damage and isn’t poisoned. Every 10 minutes, a poisoned creature can repeat the saving throw, ending the effect on itself on a success.
You can increase the damage by 3d6 for each additional mana or psi expended.
