Torpor

Torpor (minor) by Stone Gargoyle

When reduced to zero HP, the superbeing can enter into a healing coma, upon a successful save vs. death, while the body heals and regenerates. During this healing state, the superbeing does not need to eat or breathe but can perform no other actions, healing at twice normal rate while in torpor.
The superbeing can remain in torpor even when fully healed, and will not age or suffer any problems from lack of food or air. This torpor can continue for years if the superbeing wishes and the superbeing can awaken at any time desired. Once awakened, the superbeing will require air and food once more, but this comes in handy if the superbeing wishes to appear dead or to travel without needing to sustain health. There seems to be no limit to the time they can remain in torpor.
When awakening from torpor, the superbeing suffers -2 to all combat actions and gets no initiative for one full melee round. The superbeing is also -4 to all attributes until eating something, -1 for every year spent in torpor. The superbeing reduced to one attribute point in each will regain 4 from eating and then restores one attribute point per day until fully restored and can regain even points gained from skills through this daily gain.
