9.55 PHYSIOLOGY
Physiology is the study of the biological processes required for life. Alchemists trained in Physiology will find themselves able to utilise this knowledge in two primary ways: First, Alchemists may manipulate the humours, or vital fluids, of others in order to cause illnesses of varying degree, eventually gaining the power to slay another via spontaneous organ failure. Humourism, as this art is called, is based upon the tempering of another's body, aiming to increase his internal fluid level. An unrestricted Humourist is a force to be feared, but their effects may be countered by the ingestion of the ginger herb and antimony mineral. The second aspect of Physiology is the creation and control of homunculi. From within a properly equipped laboratory, the trained Alchemist may take a small sample of his own flesh, germinating it into a homunculus. Through the physiological and ethereal bond between Alchemist and homunculus, the diminutive creature may be controlled by its master, able to perform varied tasks from assaulting an opponent to being the eyes, ears, and mouth of its owner.
