Instructions
Acquire a Dragonstone. There are many ways you can do this. The simplest is to get one for free from the Crystal Key Chest in Taverley, which is located northwest of Falador. You can also purchase one from the gem store in TzHaar City, which is under the Karamja Volcano. Finally, you can get them as random loot from monsters like the Giant Mole, Bronze Dragon and Kalphite Guardian.
Get Gold Ore. You can mine it yourself at any mining facility, or you can purchase it from Ordan in Keldagrim, which is east of Rellekka.
Smelt the Gold Ore in a furnace to craft a Gold Bar. You can find furnaces in every major city.
Purchase an Amulet Mould, which is available at any crafting store.
Get a Ball of Wool from the Ardougne General Store, which is located on the west side of town.
Smelt the Gold Bar, Amulet Mould and Dragonstone together in a furnace. This creates the Dragonstone Ammy. Combine the Dragonstone Ammy with the Ball of Wool to make it into a necklace.
Enchant the Dragonstone Ammy to turn it into the Amulet of Glory. In order to succeed, you need to be a member with a Magic skill of at least 68.
