Smithy/1.03

Knights
As expected from buildings of its type, the Smithy researches armor and melee damage upgrades, as well as producing the common siege weapons (Catapult and Battering Ram). The Armorer and Weaponsmith upgrades are what truly make the building so valuable, (especially due to how quickly the Knights can get the building up and then obtaining those first researches) but for the Knights, they get one more armor research to add to the list - Full Plate Armor. Although it is applied only to their cavalry units, those units are prominant enough to the Knight race that it sees much use. However, this and the second Armorer and Weaponsmith can be quite expensive, especially early game. But with access to the Market in just tier 2, those aforementioned skills can be put aside until the Income and Trade skills are researched. That'll make getting those more expensive skills much easier.
