Transfiguration is essentially the art of changing the properties of an object. Transfiguration is a theory-based subject, including topics such as "Switching Spells" (altering only a part of some object, such as giving a human rabbit's ears); Vanishing Spells (causing an object to completely disappear); and Conjuring Spells (creating objects out of thin air). It is possible to change inanimate objects into animate ones and vice versa.
