If the artifact in question follows Equivalent Exchange and gives you bad luck if you lose it, then it can cross into Artifact of Death or Artifact of Doom.

If Clap Your Hands If You Believe is a large force in the series, expect it to be a Magic Feather in the end. Often some kind of Amplifier Artifact can bestow this super-luck.

Other times it applies all the time and can get a little ridiculous. The extent of this luck can vary greatly sometimes the lucky individual has to be careful with taking advantage of it, lest it run out at the worst possible time. Sometimes the character actually dislikes their luck, because it makes things boring or alienates friends, or if it's the kind of luck that involves their friends dying instead of themselves. Despite the trope title, this luck does not necessarily begin at birth. Usually a weak explanation is given for this luck, attributing it to some kind of supernatural force but not going into any kind of detail. They'll win every contest or lottery they enter (in especially extreme cases, they don't even need to, the winning ticket will somehow come to them).

A character that's so mind-bogglingly lucky, it defies all probability.
