How do you get justice medals in evony?

you need to attack Level 10 NPCs. at least 90k archers and 3k of everything else you have will do it. also, make sure your hero is high. by high we mean over 100 is nice, over 120 is better. do this at your own risk of course. there will be casualties, you may even lose a bunch of people and not get your medal but.. it's the way to go. good luck.
