Mithril dart tips

You need 54 smithing for mithril dart tips. We will take an example of 1 million worth of mithril bar and check how many dart tips we can make in an hour. I started with 2000 bars and used 1050 bars to make the dart tips. Each bar makes 10 dart tips, which accumulates to 10,500 dart tips.

I had 1 million worth of bars in the beginning and ended with 10,500 dart tips. So in the end, the leftover bars plus my dart tips price accumulates to 1.3 million. That means I made about 174k GP in an hour and got 50,000 XP per hour.

Adamant dart tips

You need 74 smithing for adamant dart tips. I had 13 million worth of bars at the beginning, used up the same number as the mithril bars, and ended up at the same dart tips as mithril. The dart tips sell around 2 million and the bars leftover is about 11 million which accumulates to 13 million. I made about 55k in one hour and got 65k XP per hour.

Rune dart tips

You need 89 smithing for rune dart tips. I made 10400 rune dart tips. This brings me a profit of 200k gp/hour and a total XP of 78k per hour. You need to keep in mind that the rune bar is much more expensive and cannot be bought a lot at any time, but it is pretty much a good AFK smithing method if you can afford it.
