Levicorpus

This jinx was invented by Severus Snape and recorded under his pseudonym the "Half-Blood Prince" during his time as a student at Hogwarts School of Witchcraft and Wizardry.[4][5]

There was a couple of months in 1976 where the spell became quite popular and students could barely move about without being hoisted up in the air by their ankle. In June 1976, James Potter cast this on Severus Snape while bullying him in front of a crowd.[7]

On 22 August 1994, this spell was likely used by Death Eaters during the attack at the 422nd Quidditch World Cup.[8]

At Dumbledore's Army meetings during the1995–1996 school year, various students practised this spell. Later on 18 June 1996 during the Battle of the Department of Mysteries, Luna Lovegood used this spell to incapacitate a Death Eater.[9]

In 1996 Harry Potter found the Half-Blood Prince's copy of Advanced Potion-Making that contained the spell, he used it twice during the 1996-1997 school year. In October 1996 Harry very rashly cast this on Ron Weasley without a clear idea of what the effects would be. On 30 June 1997 after the Battle of the Astronomy Tower, Harry tried and failed to cast this on Snape during Snape's departure from Hogwarts.

In 1998 this spell would be used again by Hermione Granger during the Trio's hunt for Horcruxes.
