As an action, you siphon life force to heal your wounds. One creature that you can touch or see within 18 meters must make a Fortitude saving throw. A creature isn’t affected by this spell if it doesn’t have blood in its body.
On a failed save, the target takes 3d8 necrotic damage.
On a successful save, the target takes half as much damage.
You regain health equal to half the amount of necrotic damage dealt.
You can increase the damage by 4d8 for each additional mana or psi expended.
