avariatus is done with you for the moment, so he sends you to kerian. kerian, of course, has a crafting quest for you!
the dragon crafter greets you and lets you know that you need a new claw. making one requires 2 finished resources - bronze bars and cut garnets. this requires you find the copper and tin field with a metal workstation and the gem mine with a gem workstation for the garnets.
finding the ore field is easy - you already know how to get there! take the resource road out of town and head thru the first cedar field until you get to the crossroad. there you will see the stone marker indicating the ore field direction, and prolly will see some nodes nearby.
you can hack away at the ore now, or you can continue up the road. at the top of the hill, you will find a biped mws (my shorthand for metal workstation. gws is gem workstation, sws is stone workstation, etc.) with a smelter. you can use the ped smelter to make the bars, but when making dragon specific items, you will need a scale forge - more on that later. make sure you check your game log and quest journal to make sure your quest updated when you find the field.
activate your mining ability and hack away at the nodes until you have the required raw ore. return to the mws and move to the smelter. if you have your formulas hotkeyed, select the metal bar key and open up the bronze bar item. make your needed 24 bars.
once you have made the bars, your game log and quest journal update to advise you to find the gem mine for the garnets. tell you about those soon!
