"Swift use of this jinx can freeze an attacker for a few moments, or stop a magical beast in its tracks. The jinx is a vital part of any duellist’s arsenal."
Book of Spells by Miranda Goshawk[src]

The Impediment Jinx[3] (Impedimenta),[1] also known as the Impediment Hex,[4] is a jinx that hinders the movement of the target, slowing it down or stopping it in its tracks.[1] It is a common spell used in duelling.[3]

Effects

It is only temporary,[1] lasting on average for a few seconds.[5] Although it is capable of freezing a wasp in mid-air,[1] it is ineffective against lethifolds.[4] It is also ineffective against armoured opponents, such as Acromantulas and Blast-Ended Skrewts unless it happens to hit them on their underbellies, which have no protective armour.

The jinx will usually simply immobilise a target,[1] it can also be used to push or throw a target backward[6] simply decrease the velocity of the victim's movement,[3] or can even levitate them.[7]

Known uses

"I like the look of this one, this Impediment Jinx. Should slow down anything that’s trying to attack you, Harry. We’ll start with that one."
—Hermione Granger helping Harry Potter learn the jinx[src]
