- "There never was a good knife made of bad steel."
– Benjamin Franklin
Metallurgy, the next step in the development of metal working, delivers a new level of sophistication to Renaissance weaponry and prepares its entrance into the Modern age. It also unlocks a variety of new units.
Lancers are a harder-hitting version of Knights. They have several more points of Combat Strength and receive a bonus against mounted units. However, they have a penalty during defense, making them brittle if they aren't defended.
Metallurgy is the science of metals and metallic alloys. In Civilization V the "metallurgy" technology covers the advancements in this field since the 19th century AD. In the 19th and 20th centuries, great strides have been made in all facets of metallurgy, from extraction, to the creation of new alloys, to the production of cheap, high-quality metals.
Metal remains at the heart of modern civilization. Much of the world is built of steel, and what isn't is made of aluminum or titanium. Our communications networks are made of metal, and so are our vehicles, weapons, satellites and spacecraft. Without modern metallurgy 90% of the Earth's population would starve within a year.
Despite being a Renaissance technology, between Gunpowder and Rifling, this technology's icon shows an armored knight wearing a helmet of the 12th-13th century, protections outdated for centuries, if not the idea of armor itself.
