Knocks opponent over
- "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."
- —Lupin uses this on Harry.[src]
The Knockback Jinx can be rebounded to its caster by means of either the Disarming Charm or the Shield Charm, the former being a much more common means of defence, as taught by Defence Against the Dark Arts teacher Professor Gilderoy Lockhart.
In the second year, students learn how to charge up the spell to more powerful levels (without casting the variations). To do so, one must hold their power in their wand and release their magic when the blue spell turns a strange purplish-red colour. Past this point, the spell will backfire in mid-cast, or fly back to the caster, damaging them somewhat.
This jinx was taught by Professor Quirinus Quirrell to his first year class in 1991; they 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.
Professor Gilderoy Lockhart revised this with his second year class in the 1992-1993 school year for use in duelling. He then had Harry Potter and Draco Malfoy duel each other with it, the winner earning fifty points for their house
