Jinx

A Jinx is one of the seven known spell types, affiliated with dark magic and distinguished by their negative effects used mostly for the amusement of observers and the minor discomfort of the victim. They can also be used in a defensive capacity, and hence students of Defence Against the Dark Arts may learn some of them. Jinx effects can be removed by a Counter-jinx, and they can be prevented by an Anti-Jinx.
