Warehouse Keeper Norman:
Yes, that's a good boy. Now I shall give you the list of materials that you must find.
First, we need some Gray Bone Powder to use as an abrasive. You can get it from undead monsters such as ghouls or strains. You will find plenty in the Execution Grounds of Dion.
I also need a Granite Whetstone, which is for polishing the surface of the jewel... You must find pieces of the granite golems that can be found in the Execution Grounds or in the Wasteland!
Other things that we need are the Red Pigment, which you can get from the dead seeker bat on the Execution Grounds. Last, we need some Braided Yarn, which you can get by hunting the silenos in the Plains of Dion...
Can you remember everything? I will need 70 each of all the above things. You need 7 Journeyman Gems, right? It will take 10 materials each per 1 jewel. Good luck then!
