Magicists have long since concluded that a very particular type of hex, the hexus malificus, was responsible for most curses. This curse, widely known as the Common Hex, Merlin’s Hex, or less politically correctly as the Gypsy Hex, afflicts millions every year but is easily treated by commercially available and safe counter-curses and counter-hexes.
However, newly discovered documents from notable hex researcher Jumbicus the Magnificent indicate that many occurances of what are presumes to be the Common Hex may actually be a much rarer and more serious curse, which may also occur alongside and worsen the Common Hex. Named the Swiss Curse after the first cases were catalogued near Chur in Grisons, it may explain why some otherwise normal Common Hexes last for years with debilitating results.
If a Common Hex curse is actually the Swiss Curse, or is inflicted alongside it by natural magic or by design, it may explain why normal counter-curses are sometimes ineffective as well.
The American Magical Association has declined to comment, but many fringe elements have declared this new research a victory and validation.
