A "Lucky Box" for daily participation.

I arranged for two of my friends to open the daily gift box at the same time. Today it's a Class C. All three of us got ten stamina points. Was that a fluke? No, because this isn't a lottery, but a scam. If you're giving in to your greed, it's best not to give out the reward at all, because what you're doing is spitting in the users' faces.
