Threshold Invincibility

Threshold Invincibility or Invulnerability, also known as Indestructibility or Invincibility is the ability to resist all forms of damage. One with this ability has a subliminal aura that surrounds his cells which keeps them from being damaged from impact, or the person's body has cells which absorb all manners of concussion from blows that would otherwise cause extreme damage, even fatality. Sometimes, however, it can also be used to resist any sort of assault on the body, from mental/telepathic abilities, to physical concussive force, even poisons and illnesses, until nothing short of divinity can do damage to this person. It is possible that one with this ability could die of old age, though.
