Eternal Damnation Walker!
Although the name was filled with a wildly charming and reckless flavor, its effect was simply like Ash challenging Freyja—pleasure followed by death. A +5 to luck wasn't much, but at critical moments, it could feel like a devastating -50.
Win and you would gain a piece of Moon candy, lose and it felt like losing an entire factory, even worse than gambling on a fund.
Additionally, it made one 'more likely to trigger mysterious events, more likely to face complications, more likely to be despised by fate, and more likely to experience great failures', which basically meant one was more likely to be unlucky, and once that happened, the luck would plummet to -50, akin to Meiwa unleashing a perfect combo with her hands and mouth.
If Ash had a stable life, even a normal home, he could have slightly countered the drawbacks brought by his profession.
