Good Luck Charm

Description
This "Good Luck Charm," when worn, causes the user's luck to be absorbed, amplified, and distributed indiscriminately towards people near the wearer. This causes the wearer to become incredibly unlucky, but people in close proximity to the wearer all end up with improbably good luck. This can sometimes cause conflicts, when one person's luck is another person in range's misfortune.

Even though it would be considered bad luck for something bad to happen to the wearer's friend / loved one, any unfortunate things that happen only happen to the wearer. As such, the Good Luck Charm works best (and is ultimately well worth using) in the hands of someone who is willing to take a lot of punishment and sacrifice to shield their friends from danger.
