死喰い人
In the wizarding world, use of the Dark Arts is strongly stigmatised and some aspects are illegal; however, these spells are prevalent enough that even before the rise of Voldemort, many schools (including Hogwarts) taught Defence Against the Dark Arts as a standard subject. Techniques include anti-curses and simple spells to disable or disarm attackers or fight off certain creatures. Some schools, such as Durmstrang, teach Dark Magic. A Dark Arts class is also taught at Hogwarts while it is under Death Eater control.
