Expelliarmus is a disarming spell commonly used in the Harry Potter series to disarm opponents by knocking their wands out of their hands. While Expelliarmus is not typically a lethal spell, in certain situations, it can indirectly lead to someone's death. For example, if a person is disarmed in a dangerous situation, they may be left defenseless and vulnerable to attack, potentially resulting in their death. Additionally, in the context of the Harry Potter series, the spell's effectiveness and potential lethality can also depend on the skill and intent of the person casting it. **

No, Expelliarmus does not work on Muggle weapons. Expelliarmus is a spell used in the wizarding world to disarm an opponent by causing their wand to fly out of their hand. It is specifically designed to work on magical objects, such as wands, and does not have any effect on non-magical items like Muggle weapons. Therefore, if a wizard were to use Expelliarmus on a Muggle holding a gun, for example, it would have no effect on the gun itself. **

Another spell that does not cause harm but is suitable for defense is the Disarming Charm, also known as Expelliarmus. This spell is used to disarm an opponent by causing whatever they are holding to fly out of their hand. It is a non-violent way to neutralize an attacker and protect oneself without causing harm. Additionally, the Stunning Spell, also known as Stupefy, is another non-lethal spell that can be used for defense. It temporarily stuns the target, allowing the caster to escape or gain the upper hand in a confrontation without causing lasting harm. **
