An ancient elixir, kept in a jade skull, paralyzes its victim's limbs, while increasing the sensitivity of their nerve endings tenfold. The elixir can provoke sensations in infinite variations--everything from erotic caresses to appalling lacerations. Haunted by the desire to experience the extreme sensations caused by the elixir, it's creator kills himself with his own poison, intensifying his death experience. His pursuers never found the skull. But the curse of the jade skull endures, bringing misfortune to all of those who possess it.
