Add a chest

Sometimes you have are in a tough situation. For example, all your lumberjacks are dead and you have only a few tribe members left. You are out of wood and will die unless you have a miracle. Maybe you can add a rare chest or two around the map to open and grab a few resources. This would be a common fighting spot for when you do need it and a life or death situation. You could get wood or gold from here. If you can improve on this idea post it in the comments. If you disagree explain why!
