While many know the visits of Hesedi clerics, or have been to a temple to feel the merciful touch of healing, when the touch has passed, or the clerics have moved on, it is the gift of health that keeps people alive. Health is a mixture of knowledge of mundane medicines, diet, exercise, sanitation and overall healthy lifestyle. It is the gift of the ogres originally, but has spread almost by necessity to any race that has large cities.
Combined with architecture, health provides for sanitation systems for towns and cities.
Combined with martial arts, health allows for the barbarian class.
