When I first started playing, about a year ago, the magic box shop items were abundant and cheap (<1000sp per item). When did the prices change, and will they ever change back?

If you're referring to the elixirs, that happened February 2nd and nope. (thread in announcements about it). Now the other items, I'm not sure about. I just know about the elixirs. xD

Thanks, that explains alot. I haven't been playing a while.
