Creator

Elizabeth Smudgling (c.1379)[3]

"The Disarming Charm lies at the heart of a good dueling technique. It allows the duelist to rebound an opponent's spell in the hope that the rebounded spell will strike the opponent and leave him or her vulnerable to further attack."
Miranda Goshawk[src]

The Disarming Charm,[1] also known as the Expelliarmus Spell[4] or Disarming Spell[5] (Expelliarmus) was a defensive charm which forced the victim to release whatever they were holding at the time. It is common to see this spell used in duels, to make an opponent release their wand.[1]

History

It is not known precisely who created the Disarming Charm. Some wizarding historians claim that it may have been invented by Merlin himself, others claim that its first widespread use was in Madagascar in the 11th century.[6] Even if any of this is true, the fact remains that it was not very popular until 1379, when Elizabeth Smudgling — the most likely inventor, in the opinion of Miranda Goshawk — used it in a duelling contest in Dartmoor.[6]

It became Harry Potter's signature spell, and it notably caused the death of Lord Voldemort during the Battle of Hogwarts by rebounding his Killing Curse.

Effects

""That was a Disarming Charm — as you see, I've lost my wand."

The Disarming Charm causes whatever an opponent is holding at the time — usually a wand — to fly high out of their reach.

The Disarming Charm always appears as a jet of red light; indeed, this is one of the things that makes it recognisable before the effects of the charm are seen. However the intensity of the light appears to correspond to the strength of the spell as a weak/moderate one creates a small flash of white light whereas a more powerful version manifests as a bright jet of scarlet light.

Priori Incantatem

Voldemort-Harry 1st duel (Concept Artwork for the HP4 film)

A powerful Priori Incantatem between Disarming Charm (Harry Potter) and Killing Curse (Lord Voldemort).

If two wands with the same core are forced to do battle with each other, the effect is a magical connection called Priori Incantatem. When Priori Incantatem occurred between Lord Voldemort and Harry Potter, the latter was using the Disarming Charm, a much weaker spell than the former.

Behind the scenes

"Then a blinding, jagged jet of white light flew through the air: Harry thought of lightning, but Snape had dropped to his knees and his wand had flown out of his hand"
—Dumbledore's use on Snape[src]
  • This is the signature spell of Harry Potter.
  • In the films only when a witch or wizard is locked in the Priori Incantatem is the spell scarlet. When not locked in combat it's always just a blue or white flash that will either connect with the target's hand and force the wand out of their hand or will blast them off their feet, sometimes unconcious.
  • When Dumbledore used this on Snape, it appeared as white lightning, and hence was probably a variation of it rather than the spell itself, or else an entirely different disarming spell.
  • The charm is described in The Standard Book of Spells, Grade 2, and has a spellbook purely for itself.
  • In the second film, it appears as a golden ring; from the fifth film onward it was a ball of blue light.
  • In the video games, mainly he console versions of the first and second games, the Disarming Charm worked rather like a Shield Charm, rebounding an opponent's spells upon them. This is actually also the describing of the spell in the The Standard Book of Spells series. This was mainly due to the lack of being able to disarm in past video games.
    • However, the spell returned to its more offensive use by the Order of the Phoenix game, though the GBC version of the Chamber of Secrets game also follows this scheme.
    • Also in the console version of the second game, it's possible to catch and deflect spells not only cast by prefects in the PS2 version, but it's also possible to do so on one's own backfired spell. This only works on Flipendo and Incendio however, as the other projectile spells will pass through. In the case of the former, it moves rather fast so tight timing to activate the charm is needed.
  • The Disarming Charm is referenced on Doctor Who, when Shakespeare uses it to conclude a formula used to banish the villains from earth. The Doctor (played by David Tennant) smiles after the villains are beaten and says: "Good old J.K.", referencing the author of the Harry Potter series.
