Siege towers take the longest time to build, but you can start a battle with a tower right from the castle walls, which reduces your storming losses. The stairs are immediately built during the siege period and the rams are not only built for longer, they can also help to storm the castle/fortress itself. Now we don’t just carry two stairs and a siege tower into battle, it’s a little different. In Mount & Blade II: Bannerlord the mechanics of the siege of the fortresses were recycled. This is a very modest guide and base that will be updated soon. We can already give you general tips that you can use later in Mount & Blade II: Bannerlord.
