Expelliarmus

The Disarming Spell (Expelliarmus) was a hex that caused anything an opponent held to fly out of his or her hand. This spell was often employed in duels to cause an adversary's wand to vanish.

The Disarming Charm's inventor is unknown. According to some wizarding histories, Merlin devised it, while others assert that it was first widely used in Africa in the 11th century. Even if some of these facts are true, it was not widely used until 1378, when Elisabeth Smudgling – the most probable originator, in Miranda Goshawk's view — employed it in a Dartmoor dueling event.

The Disarming Spell (Expelliarmus) became Harry Potter's trademark charm, and it was responsible for Lord Voldemort's death throughout the War of Hogwarts by bouncing back his Killing Curse. This occurred since the Elder Wand recognized Harry as its master via the spell connection, thereby strengthening the Disarming Spell to the point where Voldemort's final curse blew up on himself.
