@CountryMage Even if the animation suggests you're being cursed, it's probably still easy to take off right? I could see the theme of that becoming real in Arc's situation, but all it really said was that he bought an appearance item. I'd still find it reasonable for him to not try breaking a curse on him that's just supposed to be a "for fun" item at that point. Theme or no, it was probably still just an equipable item you can freely remove in the UI.
I think Log Horizon played around with the idea of flavor text on items becoming real for the players. Things really started getting out of hand because so many of them had high level equipment with ridiculous flavor text. It'd be interesting if that really is why his skeleton cosmetic is acting like a powerful curse, because his other items are surely crazy as well.
