Dark Magic Spells


"I know a jinx when I see one, Hagrid, I've read all about them!"
-- Hermione trying to convince Hagrid that Snape had jinxed Harry's broom (PS11)


"I was just reading about Willy Widdershins's arrest when you arrived. You know Willy turned out to be behind those regurgitating toilets back in the summer? One of his jinxes backfired, the toilet exploded and they found him lying unconscious in the wreckage covered from head to foot in -"
-- Arthur Weasley (OP22)

A jinx is a spell cast to cause damage or other negative effect. A jinx is similar to a curse, but typically not as powerful or cast with such negative intention. Jinxes are part of defensive magic, although Umbridge tried to teach that spells should never be used in this way, even in self-defense or as part of a legitimate attack. She used the textbook Defensive Magical Theory by Slinkhard:

‘He says that counter-jinxes are improperly named,’ said Hermione promptly. ‘He says “counter-jinx” is just a name people give their jinxes when they want to make them sound more acceptable (OP15)’.

A jinx is removed or undone by a counter-jinx. Defenses against jinxes are called “anti-jinxes.” Some jinxes are also referred to as hexes.
