Using the game map that you provided, Harkin's Landing should indeed be safe being 7 zones to the right, but it wasn't! I got there empty handed...What am I doing wrong? I go through the tests with an eye to collecting the three articles and once I've got them, head back to the one below the very first test. It's the one with the land mines on the way to the centre, gets me every time!
Now, when I get there I'm wearing all 3 articles and through the tests I've made use of the cheats "ouchouchouch" and "leetbuffz' to be able to survive that far. Comments?
