Old as Dust

You have been dead for so long you have become quite difficult to kill.

Prerequisite(s): Sleeper, Warren Digger, creature has been a ghoul for at least 500 years.

Benefit(s): When you are reduced to 0 hit points, you are not destroyed— you cannot be killed unless your body is completely destroyed with fire or doused in holy water, or you take damage from a cure spell or channeled positive energy after you’ve been reduced to 0 hit points. Anytime you are reduced to 0 hit points, you remain unconscious until you are healed or until the following midnight, at which time you regain 1 hit point per Hit Die and awaken.
