Dont bother with this money maker, Elder Rune Bars Smithing
I saw this on a video recently, it said just smelt Elder Rune Bars, and the bonus bars you get will make like 4m prof an hour. Well i tested this, and it does not work at all.
Here is the test:
Lets try smithing 1000 Bars
Rune Bar: 3,035,000
Dark Animica: 4,700,000
Light Animica: 7,907,000
Total Cost: $15,642,000
Time Spent Smithing (With Smithing Gauntlets): 40 Minutes
Price Calculator for Bars, including additional bars: $15,694,400
Actual Sold Price: $15,695,488
So total profit is... Nothing ;)
$15,695,488 - $15,642,000
Aka.. dont bother.
