The connection of your spirit to your physical form is particularly strong.
Benefits: Instead of instantly being destroyed or forced into gaseous form at zero hit points, you instead remain intact until you are reduced to your negative Charisma score. Though you fall seemingly dead, you can be restored by negative energy (or blood in the case of vampires) as normal. However if you have not been healed after minutes equal to your level have passed, then you suffer the normal consequences of being reduced to zero hit points.
