Smelter

The Smelter plays a vital role in improving your metal output by increasing the yield of mines in its host city. Unlike the Foundry of Chronicles it does not host Supply research - that however is handled by another building, the Fort.

The Jin can construct Smelters without requiring any Technological upgrades, making them highly efficient in the accumulation of resources from the early game, while the Dian will receive Metallurgy upgrades for free uponobtaining the prerequisite technologies and upgrades for them.
