The iron mine is used for iron production. Iron is necessary for the most advanced barracks units as equipment.
Two laborers work at the building: one extracts the raw ore and brings it to the surface, while the other helps to smelt it into bars. Available bars can then be carried away with the help of an ox.
The iron mine has a stockpile, which fills up over time. When its maximum capacity is reached (about ten ingots), workers cease production.
Iron can be used for weapon production at:
- a blacksmith's workshop, for forging swords;
- a forge workshop, for crafting maces;
- an armourer's workshop, for crafting metal armour.
