Engines of War  introduces an Engineer, who uses new Resource cards to build Catapults, Ballistas, Barricades, and more, to better defend the Castle from the growing capabilities of the Monsters.

Now they are charging at you with a Siege Tower, War Wagon, and a Battering Ram. And they've enlisted the help of a Shaman, Breathtaker, and Goblin Saboteurs. Prepare your forces! The fight just added  Engines of War!
