"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]


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."
