i get 500 stick people to help reload the boiling oil ,guns etc, and to repair/ improve the castle. Chuck Norris goes out and roundhouse kicks the giant stickman and sends it to mars anyway ( =P) . i also build large trebuchets, snake trenches, and ballista
Buy the dark shield and machine gun turret. Also I set up a flame guardian from epic war 3 that is over 60 ft tall adn causes tornados of flames to protect the castle.
