A Curse is one of the seven known spell types and the worst kind of Dark Magic. Curses are used with the intention of causing harm, control, or even bring death to the victim. Like hexes, students are taught them in Defence Against the Dark Arts for protective purposes.
Most curses can be undone by a Counter-curse.
Behind the scenes
- Wizards may have the ability to send curses in the post. This is unconfirmed, but in Harry Potter and the Goblet of Fire a piece of Hermione Granger's hate mail claimed that it is possible.
- According to W.O.M.B.A.T., it may not be possible to cure a curse victim without the correct counter-curse.
- J. K. Rowling defined curses as "the worst kinds of dark magic"..
- Whilst Barty Crouch once said that the Killing Curse cannot be blocked, this is not strictly true. For example, one could obstruct its path with another object, such as Albus Dumbledore did when he animated the Fountain of Magical Brethren; it can also be blocked by Sacrificial protection.
