Expecto Patronum or the Patronus Charm creates a shining silver guardian in the form of an animal called a Patronus. These animals often have significant meaning to the caster, such as a precious memory or connection to the caster. For example, in the original canon, Harry's Patronus was a stag, signifying the connection Harry felt with his father. In order to cast a Patronus, the caster must focus on a positive memory or feeling designed to drive fear away. This is later explained by Harry as people subconsciously shielding themselves from the fear of Death, as he correctly deduces that Dementors are in fact a physical manifestation of Death and humanity's fear thereof. Thus, the Patronus is designed to shield the caster from the pain of the fear of Death. This is how a Patronus is able to confer protection from dementors, their primary purpose. However, a Patronus is also capable of locating other Patronuses or other people and can convey messages to people. They also generate light, variable on how powerful the Patronus is, as seen with Harry's vastly superior Patronus outshining even Dumbledore's. The difficulty in casting a Patronus comes not from challenging wand motions or even the total amount of magic in your body, but from mustering the mental willpower to face down fear itself and drive it away. Thus, it draws on emotions in addition to standard spell requirements.
