Between the mining place as well as the mage training region, there's a man named Mani, a buff, and a booth filled with pickaxes. He will sell pickaxes, and OSRS gold after the pursuit he will smelt your ores in a low cost (and there's a follow up quest, where you make him an anvil, he will then smith on for you (at a cost )). Speak to himand instead of asking to see his inventory, ask about an Armanite Bar.
Have you ever been sold a special bar of Armanite recently? Yes! It's a marvel! So rare -- only one source in life. It's incredibly powerful. I'm busy creating a prototype Armanite pickaxe. That is all good and well, but I want it. Impossible. I've already started the procedures of making a pickaxe. You will never get another bar. You did say there was a source somewhere. Would you not inform me it is?
I could, but you would need a very strong furnace to smelt it. I've plans for an extreme heat-producing machine. Should you bring me Armanite Ore, and 5 pieces of molten glass, then I can smelt you a bar. Okay. Talk to him again. The island of Entrana has excellent facilities. Speak to him to get more info. It's rumoured that Armanite Ore is actually the flesh of a monster made of ores. Recently, scattered ores are discovered northwest of Varrock. I would check around there.
Head to the north-west of Varrock. . There'll also be a mysterious rock, coloured purple. If you begin to mine it (45 mining required), it lifts up and it is actually a beast made from rock! (Level 75 Rockbeast). Kill it, and take the Armanite Ore.. There would be Old School RS Gold a random fall of a metal, Bronze, or Iron pub. Head to Entrana (or someplace else), make 5 molten glassand take it back to mani. Speak to mani.
