The spell was used a third time by Harry to swap the covers of his second-hand and brand-new copies of Advanced Potion-Making. Causes the target to move downwards. Harry Potter later used it to try and reawaken a cursed Dumbledore in the seaside cave. This spell may be an invention of Hermione Granger; it is unclear in the Goblet of Fire text whether she invented it herself or found it through research. This spell was used by Tom Riddle to open the chest in which Aragog was hidden.
