Hides resources from attackers, depending on the level of the building.
Ex: lvl 10 dungeon hides 1000 of each resource when someone is raiding you. If you got 3000 of each resource in the city, and a lvl 10 dungeon that hides 1000, the atacker will steal the difference, thats 2000 of each resource.
