Leonis, whats the % chance you get of getting an item when you open the box with no key?
We don't generally share this kind of information because it turns it in to a numbers game, rather than what it's intended to be.
so its more a really im related thing
cuz without key the chance you get anything is very very low
The box explains to you forcing it open will make it angry and not want to give you anything. And for a item that drops in-game for FREE, it's perfectly acceptable to take your chances. The keys only provide that shortcut in time for those who can't spend the hours farming like others, so they're guaranteed an item. It's not much different than spending points on refiling your Game Arena energy, to cut down on the time you'd have to otherwise wait to refill.
For the Silver key, you're guaranteed one of the 12 items you could get from this event. To help save more time, the Gold key lets you choose which type of item it is, but there's still that element of chance, to getting the one you might want.
