Weapons, armor, off-hands, bags, capes, food and potions, every tier and enchantment. Each city crafts a few categories with a 15% bonus (food in Caerleon, potions in Brecilien), and focus raises how much of the materials come back: from 15% to 48%. Food and potions are made in batches; the prices here are per item.
Materials are bought from sell orders in the crafting city; the resources that can come back count for their price less the return rate, artifacts in full. Hover the cost for the recipe. The item is priced at normal quality, so a better roll only adds to the profit. The station fee is estimated from the item's materials. City bonuses: Fort Sterling (cloth armor, plate helmets, hammers, spears, holy staffs), Lymhurst (bows, swords, arcane staffs, leather hoods, leather shoes), Bridgewatch (plate armor, crossbows, daggers, cursed staffs, cloth sandals), Martlock (axes, quarterstaffs, frost staffs, plate boots, books, shields, torches and horns), Thetford (maces, fire staffs, nature staffs, leather jackets, cloth cowls), Caerleon (war gloves, food), Brecilien (capes, bags, satchels, potions).
