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, the target takes 4d8 poison damage and is poisoned for the duration.
On a successful save, the target 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 6d8 for each additional mana or psi expended.
