At the Armory building you may research improvements that make your soldiers more effective in combat and provide them with better armor.

Thor's Armory is special, for it enables all the improvements in the Archaic Age, though more powerful armor and weapons still require early ones as prerequisites, and the costs may be prohibitive. Thor also has access to additional improvements beyond the iron level.

The dwarves of Norse mythology were master smiths, and constructed virtually all of the legendary weapons, including Odin's spear, Gungnir, and Thor's hammer, Mjolnir.
