This spell was a transfiguration which turns books into other books.
In the 1995–1996 school year when Dolores Umbridge saw Harry Potter and the other Dumbledore's Army members walking towards Hogwarts Castle from the Clock Tower Courtyard carrying defensive books, she used this spell to turn them into Dark Arts Defence: Basics for Beginners.
Behind the scenes
- While the existence of the spell can be considered canon, its use by Umbridge cannot, as there is no indication in the novel that Umbridge caught Dumbledore's Army at any of their activities prior to Marietta Edgecombe's betrayal of the group.
