Luck Magic
Luck magic is a controversial magic less for its uses, and more for the belief of its existence; it is one of the rarest magics known, and also the hardest to prove real. People argue if it is actually a real magic, or if those who believed to use it are simply prophetic or in very coincidental situations.
It is the manipulation of luck via magical means; changing the very nature of chance surrounding an object, person, or event. Those who believe in luck magic believe it can never guarantee an outcome; but it can increase the chance of the desired one greatly.
Most commonly, witches and mages who use luck magic are hired by people trying for children. Second-most commonly, they are approached by gamblers and are part of the reason many bars and events will have aura-sensors on-staff to prevent cheating.
