Transfiguration

Transfiguration is the art of changing of the form and appearance of an object and the &lt;!-- vanishing --&gt;Vanishing Spell of objects. This magical art is governed by Gamp's Law of Elemental Transfiguration which acknowledges the limits to the power of this branch of magic.

Hogwarts School of Witchcraft and Wizardry devotes an entire section of their curriculum to Transfiguration.
