Path of the Skinwalker

To choose this subclass you need to go on a spirit walk. Spirit walks can take a day or a week to fulfill. The animal which represents you will walk up to the individual and offer its life. The Skinwalker must then kill it eat its heart and skin it. The skin taking on the magic of the wild will then wrap itself around the Skinwalker and transform them into the animal, as they become one.
