enable your dragon scalecraft ability, head over the bridge to the craft cave, and turn right. you will see the scaleforge. a scale forge is a workstation exclusive to dragons - bipeds cannot use it and have no real need to, altho it would be nice to make scales and claws for newbies.
by now, you are familiar with the creation process - suffice to say, it is identical to making any other item in istaria. open knowledge tab, select item you wish to create, equip the needed tool/ability, choose amount, click create. (someday, i will have to tell you about deconstructing items, handy for craft level grinding)
once you have created the item, check your inventory and journal, and return to jemenoth.
before you set off on your next quest for the dragon crafter, you might want to equip your claw. not that you will need it, but hey, you just made it, why not? it's pretty swank, after all! so, if you have closed your inventory window, open it and highlight the claw. right click and choose the equip option. open your equipment tab and notice that your claw is now equipped, along with your dragon pack. notice, at the bottom of the screen, you see your current hoard level (which i believe i have told you about already). you will also notice other open slots, one of which you will fill soon enough.
but more about that later!! ;-}p
