Smelting iron bars
|10 (19 recommended)|
|Inputs (1,680,000)||Outputs (2,600,400)|
4,000 × Iron ore (1,680,000)
2,200 × Iron bar (2,600,400)
It's recommended that the player is at least level 19 to do this method since at that level you have a 10% chance of doubling a bar without using any resources while smelting. It should take around 52 seconds to make an inventory of iron bars, deposit them into your metal bank and then start the process over again. This makes it possible to smith 2,000 bars an hour and with the 10% chance of doubling the bar while smelting you get, on average, 2200 bars an hour.
If the player has yet to reach level 19, the profit per hour would be 667,926.
