Patient Zero is a unique spore carrier found in the Big MT.


A human test-subject became what was considered an unsuccessful experiment because the patient "died" one day after being exposed to Beauveria mordicana fungi. However when the scientists returned to the laboratory, the body of Patient Zero had disappeared. It presumably fled to the X-22 botanical garden where it has settled.


Patient Zero has as many hit points as a spore carrier beast, but is a much higher level than it. Patient Zero additionally has a weaker attack than a beast. Upon death, Patient Zero carries potent healing items.
