Defence Agains Dark Arts 103. The Jelly Legs Jinx - Locomotor Wibbly

 The Jelly-Legs Jinx

For all visible purposes, when the Jelly-Legs Jinx is successfully cast, your opponent’s legs will begin to jiggle uncontrollably

The incantation for the Jelly-Legs Jinx is “Locomotor Wibbly” (LOH-cah-MOH-tor WIH-blee) and the wand movement is a rapid squiggly motion that starts on the left and moves up, over to the right, and down. Imagine that you’re drawing squiggles on your target’s legs, but it doesn’t have to be directly aimed at them. The movement will suffice.

The willpower needed to be applied to this spell is dependent on how long you want the target’s legs to remain jiggly. If you apply a low willpower, they will be unstable for about ten seconds. However, with a stronger application of willpower, you can cause a person’s legs to be unsupportive for up to three minutes. Finally, we come to concentration. For this component, you need to direct your mind to the jiggling of your target’s legs. Mentally visualize their legs becoming unstable beneath them, jiggling uncontrollably until they have no choice but to fall over
