Burning down Lionheart's castle is a must have tradition. Btw you can kill their Lord by fire. Just need one more archer who shoots at him so he keeps walking down into the fire.
Hero Project you go into your barracks and hit 1 for archers, 2 for spearmen, 3 for macemen, 4 for crossbowmen, 5 for pikemen, 6 for swordsmen, 7 for knights and then click where you want to put it. Mercenary post is 1 for Arabian archers, 2 for slaves, 3 for slingers, 4 for assassins, 5 for horse archers, 6 for Arabian swordsmen, 7 for firethowers. Engineers guild is 1 for engineers, 2 for laddermen. Tunnelers guild is 1 for tunnelers. As you can see I love making unnecessarily long comments
