Ingredient links show where to gather the inputs. Quantities depend on the recipe and the number of attempts; use the recipe window for the amount consumed per craft. Buy vendor supplies such as thread, parchment, dyes and vials from profession suppliers.

Keep bolts, powders, grinding stones and other intermediate crafts for later recipes. Yellow recipes may require extra attempts. Vendor recipes and specialization recipes must be learned before you can use them.

Farm the materials

Ore links above are the raw inputs. Smelt the corresponding bars with Mining at a forge. Bronze uses Copper and Tin; Steel uses Iron and vendor Coal.
