Conjuration is a branch of Transfiguration. Conjurations are distinguished from the other branches of transfiguration by their ability to transfigure the desired object from 'thin air'. Although some are simpler and are taught to younger students, most conjurations are N.E.W.T.-level and are taught to Sixth years and above at Hogwarts School of Witchcraft and Wizardry, such as Aguamenti. According to Gamp's Law of Elemental Transfiguration, food cannot be conjured.
