“Mine own invention, my masterpiece; the crowning achievement of my career. Bottled good fortune. Brewed correctly the drinker of this potion will be lucky in all their endeavours, but be warned … excessive consumption is highly toxic and can cause extreme recklessness. Fans of Quidditch were quick to protest that a potion which gives the drinker good luck was hardly fair and use of my potion was banned, quite rightly, from all competitive events … except potion-making tournaments.”
Felix Felicis, also called “Liquid Luck”, is a magical potion that makes the drinker lucky for a period of time, during which everything they attempt will be successful.
It is meant to be used sparingly, however, as it causes giddiness, recklessness, and dangerous overconfidence if taken in excess. Felix is highly toxic in large quantities and is also a banned substance in all organised competitions, such as Quidditch, along with all other methods of cheating. It is very difficult to make, disastrous if made wrong, and requires six months to stew before it is ready to be consumed.
