As an action, you unleash a virulent disease on a creature that you can touch or see within 18 meters. The target must make a Fortitude saving throw.
On a failed save, it takes 2d10 necrotic damage.
On a successful save, the creature takes half as much damage.
The damage can’t reduce the target’s health below 1. If the target fails the saving throw, its maximum health is reduced for 1 hour by an amount equal to the necrotic damage it took. Any effect that removes a disease allows a creature’s maximum health to return to normal before that time passes.
You can increase the damage by 3d10 for each additional mana or psi expended.
