As an action, you siphon life force from a creature that you can touch or see within 10 meters to heal your wounds. The creature must make a Fortitude saving throw. If the creature is a construct or an undead, the spell has no effect on it.

On a failure, it takes 3d8 necrotic damage.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

You regain health equal to half the amount of necrotic damage dealt.

Augment

You can increase the damage by 3d8 for each additional mana expended.
