curse
A spell is to read some sentences or say some vicious words or formulas in a mysterious and strange way that others don't know, hoping that others will not go well. The caster always hides himself from the cursed person. The content is irrational and malicious, which is a feudal superstitious activity that destroys social relations.
The tone of many curses is affirmative, while curses are negative. But it doesn't mean that magic is weak magic. The correct spell is a powerful magic tool against curses, ominous spells and witchcraft.
