Control disease allows the Jedi to direct and control the anti-bodies and healing resources of her body to throw off or to resist diseases within the body. Using the power requires the Jedi to mediate for half a hour. If the disease is life-threatening or long-standing, the Jedi must make repeated skill attempts over the course of several weeks or months to cure the disease entirely. (Gamemaster's discretion as to how many rolls are needed and how often.)
