Lycanthrope

A lycanthrope is an intelligent humanoid infected with a communicable disease/curse that transforms their minds and bodies. It enhances strength, senses, and confidence that can often lead to arrogance or grandiosity. After a few days, the disease grants the ability to transform into a monstrous beast, sometimes involuntarily. Wood elves associated with cults of Nimrodel have been known to treat the curse as a sacrament or blessing. The disease is curable.
