# Description [[Oni]] have two distinct forms: Folk and True. At will, Oni can effortlessly change forms in smooth transitions. The [[Cathexis]] that transforms their body also captures their clothes and held belongings, with the exception of any other living being. Not even living plants can be absorbed during their transformation. Particularly large and bulky items or items of intense arcane power may also fail to be absorbed, depending on the narrative circumstances. Oni can tell when something will or will not transform with them instinctively; they are never surprised if something is not absorbed. During combat, shifting forms is a considered a Great [[Actions|Action]]. Oni maintain a level of latent [[Cathexis|cathectic]] energy to maintain their [[Folk]] form. When denied access to this, Oni must either tap into an external source or immediately regress into their True Form.
