As an action, a ray of sickening greenish energy lashes out toward a creature within 18 meters who must make a Fortitude saving throw against poison.
On a failed save, it takes 3d10 poison damage and is poisoned for the duration.
On a successful save, it takes half as much damage and isn’t poisoned.
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 5d10 for each additional mana or psi expended.
