Dislodges an weapon from another person’s hand

Expelliarmus is the Disarming Charm that forces whatever an opponent is holding (usually a wand) to fly out of their hand. It is one of the most commonly used defensive spells in the Harry Potter series. The other options are different spells: Expecto Patronum produces a Patronus, Ennervate revives stunned people, and Engorgio enlarges objects.
