I don't know why, but I actually really like this series. Maybe it's because I'm always the person in games that prefers to be a super crafting person rather than a damage-type person. This feels like a rather unique and refreshing change from the regular stories.
So its a necklace that causes the wearer to have no way of sleeping peacefully but it has auto return....... hmmmmmm this necklace is a weapon of sleep deprivation!
It’s craft-able so I guess he could break it down and reforge it. Question is whether they will believe him and let him.
Bet it was a recent gift from some conspirator like an uncle.
Time to go beat the shit out of whoever made the necklace or put those skills on it depending on if it had the skills on it when it was made or where placed on it.
