[X]: Poetry and art. While not a major focus of your studies, every young man of good birth is required to learn how to compose beautiful poems, which form the basis of nearly every form of formal social interaction, from courtship to seeking allies to simply connecting with friends.
[X]: The rituals of summoning and communing with spirits and ghosts. These allow a practitioner to speak with hidden or trapped spirits, and summon forth gods and spirits to help with a particular task, and even bind them as shikigami, a role somewhere between patron spirit and familiar. While communing with spirits is a necessary part of nearly every Onmyoji's life and work, the summoning of spirits is a tightly controlled practice, and misuse of it in the form of necromancy or other improper acts can result in severe censure from the Onmyoryo, the bureau of divination.
