The Disarming Charm is a defensive spell that aims to disarm an opponent, causing whatever is in the persons hand at the time, usually a wand, to fly out of his or her hand.

It has been known to knock an opponent backwards in some cases. This may depend on whether the spell strikes an opponent's wand or body.

Syntax: Expelliarmus

Effect: The target must make a reflex save, or be disarmed of any weapons in either hand. The spell causes minor-moderate damage.
