# Expelliarmus

**Expelliarmus**, the Disarming Charm, forces an opponent's weapon — usually a wand —
out of their hand. Though simple, it is one of the most practical spells in a duel and
became something of a signature for Harry Potter, who relied on it even when more
violent magic was expected of him.

In the right hands, a well-timed *Expelliarmus* can turn a duel without ever causing
harm — a fact that defined Harry's approach to combat.
