I think at an arena like wow in strangleton. A place in an area pvp flaged with a chest n the middle. This chest spans maybe all 6 hours. In this chest are an special item. For an amount of this items 12, 24 or more the owner can get a special tool. Maybe a tool to gather recoursces without changing the tools - one tool for all with nice stats. Everone who owns this tool gets an archievment or special titel.
