Tyche's Blessing or Tyche's Curse

In a world where luck appears to be random, it is possible for a person to be born with a magical predisposition to either good or bad luck. For most, this is relatively harmless and, while that person may be recognised as lucky or unlucky, the magical root can go completely unnoticed. However, rarely, the condition can be extreme enough to warrant intervention.   Possible forms of intervention for extreme bad luck can include the carrying of charms or amulets, and long-term close contact with someone predisposed to good luck. The latter can be tricky to navigate personally as the contrast can be psychologically challenging for the unlucky person. However, good luck wears down bad luck over time, given enough exposure.   There are risks associated with two people with opposing luck in close contact. The scenario is rare, but in instances where extreme good luck kicks in while the two parties are together, there can be a delayed backlash of extreme bad luck later after the two have parted. To take an example, if the person with good luck survives a potentially fatal accident or incident purely through extreme luck, something as devastating as the former is miraculous could fall upon the unlucky person, which may just be the beginning of an unusually unlucky streak. The streak can be broken by intervention from lucky or even luck-neutral parties, but rarely by the unlucky person alone.
