C4t2's TerraFirma Create

C4t2's TerraFirma Create is a Modpack that primarily revolves around TerraFirmaCraft, with a few addons, although there's also a ton of other mods such as Create and Farmer's delight.

To get vanilla copper or iron you have to make something first, that you then grind down with Create crushing wheels such as minecarts for iron, and lightning rods for copper. Terrafirma brass and nickel automatically works with Create.
