"The incantation for the knockback jinx is 'Flipendo'. This jinx is the most utilitarian of Grade 2 spell, in that it will allow the caster to 'knock back' an opponent or object and can also be used to push and activate certain magically charmed switches. Like many Grade 2 spells, Flipendo can be targeted."
The Standard Book of Spells, Grade 2

The Knockback Jinx[2][1] (Flipendo[2][1]) is a jinx that knocks back the target back, while prominently used for duelling, it has non-combatant usage, such as for activating magically charmed switches.[2] It is covered in both Quentin Trimble's The Dark Forces: A Guide to Self-Protection[1] and Miranda Goshawk's The Standard Book of Spells, Grade 2.

History

During the 1984–1985 school year, it was covered by Filius Flitwick in Charms class for first years.[3]

During the 1991–1992 school year, this jinx was instead taught to first years in the Defence Against the Dark Arts class by Professor Quirinus Quirrell. Students later used it to defeat the various imps, fire crabs, and pixies residing in Hogwarts Castle, as well as helping to protect themselves against the monsters in the Forbidden Forest.[4]

Effect

The Knockback Jinx feels like a blow to the chest, knocking back a victim or object,[1] along with "a loud bang."[5] The jinx also can also break fragile objects. To counter it, the Knockback Jinx can be rebounded to its caster by means of either the Disarming Charm or the Shield Charm, as many other spells can, or simply dodged.

Known uses

"There was a loud bang and he felt himself flying backwards as if punched; as he slammed into the kitchen wall and slid to the floor, he glimpsed the tail of Lupin's cloak disappearing round the door."
—Remus Lupin uses this spell on Harry Potter[src]
Caster(s) Date Notes
Dobby 30 May, 1993 After Lucius Malfoy realised that Harry Potter freed Lucius' House-elf, Dobby, with a sock, Dobby used magic that sent Lucius flying backwards as the latter was about to curse Harry. As this was accomplished by House-elf magic, without a wand,[6] it may not have been exactly the same as a traditional knockback jynx, but the effect was certainly comparable.
Harry Potter 17 December, 1992 Professor Gilderoy Lockhart revised this with his second year class in the 1992-1993 school year for use in duelling.[2] He then had Harry Potter and Draco Malfoy duel each other with it.[2]
Draco Malfoy
Alastor Moody 18 June, 1996 During the Battle of the Departments of Mysteries, Alastor Moody used this jinx to knock a Death Eater off the ground and hit a large rock before disappearing behind it.

Remus Lupin 1 September, 1997 On 1 September, 1997, Harry had this spell used on him once more, this time by Remus Lupin at 12 Grimmauld Place.[8]
