Complete the two Drakescale Armor quests with Wade the armor crafter in Denerim. During the "Search For The Urn of Sacred Ashes" quest, you will encounter a dragon. Defeat it to receive the "Dragon Scale" item. When you return to Denerim, do not go to Wade's. Instead, go to Gorim at the opposite side of the Open Market and sell him the Dragon Scale. Then, go to Wades, tell him you have the Dragon Scale, and ask him to make the strongest armor. After the dialogue, Wade will give you a complete set of Wade's Superior Dragonbone Plate Armor. Exit Wade's and go back to Gorim. Buy back the Dragon Scale. Exit the merchant and you will notice that the quest has been reissued. Talk to Gorim again and sell him back the Dragon Scale. After that, go back to Wade's and have him make another set of armor. Under normal conditions you can sell the entire set for around 8 gold pieces, but if you chose the Dwarf noble as your starting character Gorim will buy it from you for double that amount.
