If you kill and win more fights the higher your strength goes, it's like if you got a game which allows u to create something, it takes time for you to build up the stats, and the way to do that in this case is kill as many peeps as possible, which as i can see Lerkie your doing quite well at...and the people who don't bother and just defend themselves are going to stay on the same level, so the more you fight the more chance you have in going to the second level...get me?
