i was thinking about kinda right away, you would need to make a quest in order to get an item that as traded to the battlefield entrace would release the cap, those quests would not meant to be made by low level players tough (i dunno getting a drop from high level monsters) something that if you want to do alone at a high level you should be able to without much trouble but at low level woudnt (unless you got help from a friend of course)
