Onyx amulet

The Onyx amulet is made by using an onyx and a gold bar on a furnace with an amulet mould in your inventory. This requires a Crafting level of 90 and provides 165 Crafting experience when made. The amulet must be strung before wearing by using a ball of wool or the String Jewellery spell (Lunar spells are needed to cast this). Stringing provides an additional 4 Crafting experience.

The Onyx amulet can be enchanted into an amulet of fury through the use of the Lvl-6 Enchant spell which requires level 87 Magic, or an enchant onyx tablet made from a lectern in a player-owned house.

Trivia

 * The ball of wool used to make this amulet seems to be stained black in the making of this amulet. Additionally, despite having to use a gold bar to make an onyx amulet, there is no gold visible on the model of the amulet.
