They may be tougher to kill, but the beer-swilling bastards are considerably poorer now after I wandered through their gold mine. Ha! I don’t really have anything to spend gold on until I get better smelters, though.
I’m not sure how many more areas I have left to go through in Overlord, but I know there’s still at least the Heaven’s Peak area that’s still mostly unfinished and a desert area, so hopefully it’s not too close to being done already.
