Here's what you might be thinking about:
* The Triwizard Tournament: The Goblet of Fire is the key element in this dangerous competition, not a jinx. It's a magical artifact used to select the champions.
* Curses and Hexes: There are many curses and hexes in the Harry Potter universe. For example, a jinx might be a simple spell that causes someone to trip, or a more serious hex like the "Imperio" curse that controls someone's mind.
* The "Dementor's Kiss": This is a powerful curse, not a jinx, and it is mentioned in "Goblet of Fire." It's a fate worse than death that can suck a person's soul out.
To clarify:
* Jinx: A general term for a curse or hex, often with less severe consequences.
* Triwizard Tournament: A magical competition with dangerous tasks, where "jinxes" could potentially be used as weapons.
* Curses and Hexes: Specific spells with varying levels of power and effects.
