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 turns an ordinary day into an extraordinary one.
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.
