Rejuv-Chamber — This large hospital appliance (looks like an iron lung) is used to repair any type of medical problem. The patient is placed inside the chamber and percentile dice are rolled. A patient who has lost up to one halt of his original hit points has a 100% chance of having all lost hit points restored, with a 75% chance for a patient with one-fourth remaining, and a 50% chance for a patient with less than one-fourth of his original hit points remaining. Note, however, that a patient may only use a rejuv-chamber once per month. Each additional use of the rejuv-chamber in a one month period gives the patient a 30% chance of death through system-shock.
