As an action, you wither a creature or plant that you can touch or see within 18 meters, draining moisture and vitality from it. The target must make a Fortitude saving throw. The target takes 3d12 necrotic damage on a failed save, or half as much damage on a successful one. The spell has no effect on undead or constructs.

If you target a plant creature or a magical plant, it makes the saving throw with disadvantage, and the spell deals maximum damage to it.

If you target a nonmagical plant that isn’t a creature, such as a tree or shrub, it doesn’t make a saving throw; it simply withers and dies.

Augment

You can increase the damage by 4d12 for each additional mana or psi expended.
