Iron Ingots
Secure Iron Ingots for recipes that need refined metal by mining Iron Shards and smelting them after the Furnace is available.
Scrap Metal piles in the Greylands north of the Oak Forest; later, Sewers and Forbidden Monuments also have Scrap Metal.
Repeat the Greylands scavenging and Furnace processing as needed while Scrap Metal is available. Artifact conversion is a supplemental route, not a substitute for checking its required inputs.
Stop when you have enough ingots for the immediate recipe plus any reserve you intend to keep; switch to another progression task if Windmill or Furnace access is still missing.
