"‘Revelio’ is a revealing Charm, which has several variations and applications. When ‘Revelio’ is used directly on a person, it removes magical disguises."
— Description[src]

The Revelio Charm[5] (Revelio) was a charm[1] used to reveal concealed objects,[2] messages, invisible things, and passages[6] or any other secretly written messages and hidden markings. It was considered difficult for a second-year student at Hogwarts School of Witchcraft and Wizardry.[7]

It may have also been used to reveal the true appearance of someone who changed their appearance with a spell.[8]

It had no effect on a transformed Animagus;[9] a different spell had to be used to force them back into human form.[10] It was also useful for revealing disguised Chameleon Ghouls.[11]

Known uses

On 7 December, 1926, Newt Scamander used this spell on Percival Graves, revealing that he was actually Gellert Grindelwald who had assumed Graves' appearance using Human Transfiguration.[8]

Nine months later, in September 1927, Newt once again used the spell while looking for Tina Goldstein in Paris, revealing that a Zouwu had been on the location of his investigations.[12]

In the 1985–1986 school year at Hogwarts School of Witchcraft and Wizardry, Jacob's sibling was taught this spell by Minerva McGonagall in private in their second year,[7] and used it to untransfigure a cauldron into a cat and later to reveal the Vanishing Stairs.[6]

In the 1989–1990 school year, Jacob's sibling again used the charm, this time in Knockturn Alley to reveal Mundungus Fletcher who was disguised as the Dark Witch from Knockturn Alley, in front of Ben Copper and Knockturn Alley. They suspected it was him in disguise given the unconvincing way he talked as the Dark Witch.[13]
