On casting Nystul's magic aura, a touched item would be detected as either as an utterly non-magical item or as a magic item of the caster's choosing. For example, the caster could pick up a random sword and make it appear as if it had the vorpal quality. However, the spell did not change the appearance of the object; for example, claiming a sword to be a vorpal sword, despite the sword not being of a quality that could hold any magic, was bound to raise suspicions. Furthermore, there was a chance for the magical aura to be determined as fake by means of investigating the enchanted object, for example by using an identify spell.
