Siphon Life

Experiences with necromantic energy have left a permanent mark on you, casting you in a deathlike pallor, chilling your body temperature to be ice-cold, turning your very blood black, and giving you the power to rip out an enemy's life force. Strike with an unarmed attack. If you hit and the target is a living creature, it takes an additional ] damage, depending on its Fortitude save. If the target takes any void damage, you gain an equal number of temporary Hit Points, which last for 1 minute.

Critical Success The target takes no additional void damage and becomes temporarily immune for 1 minute.

Success The target takes half the additional void damage.

Failure The target takes full additional void damage.

Critical Failure The target takes double the additional void damage.
