Siege Engine Edit
The Siege engine is used in the Conquest of other civilisations and may also be used by enemies to attack your fortifications. It can be bought for 50 metal, 50 leather and 200 wood after buying the Mathematics upgrade. Siege engines can also be captured after a failed invasion attempt from an enemy. Instead of dealing damage when you try to raid other civilisations they destroy fortifications. If you lose in a raid you will lose all your siege engines which will require you to create more. Siege Engines are only useful when you start raiding the Large Town or higher since they can have fortifications when you try to raid them.
