Blacksmithing is the best combined with Mining, and I highly recommend leveling Mining and Blacksmithing together because you will need a lot of gold if you want to buy everything from the Auction House.
I recommend using Zygor's 1-60 Leveling Guide if you are still leveling your character or you just started a new alt. The guide is in a small window on your main screen in-game. All the detail that you need to complete the quests are included. You’ll never have to switch back to a website, or even the in-game main map to see where you have to go or what’s next. And if you are low on gold, I recommend trying this Gold Making Guide, it can help you to make a lot of gold.
Learning Legion Blacksmithing
First, visit your Blacksmithing trainer Alard Schmied at Dalaran (Legion). Just walk up to a guard in the city, you can ask them where the Blacksmithing trainer is located.
After you learn Blacksmithing, pick up the quest Strange New Ores from Alard Schmied (Requires level 10).
Blacksmithing recipes are unlocked by doing quests for your profession trainer Alard Schmied.
You should get to level 45 and finish every Blacksmithing quest before you continue this guide.
There is 34 Blacksmithing quest in total, they are pretty straight forward, so I will not write down the details of every quest. Some of the quests lead you to dungeons, but you can finish every quest easily in a few hours if you start them at 50. Otherwise, you will have to wait because later quests have a level requirement.
Most Legion recipes now have 3 ranks. Higher rank recipes allow you to craft an item for fewer materials, and they stay orange for a lot longer (grants guaranteed skill-ups). Therefore, you should only use rank 3 recipes when you can.
Rank 3 recipes come from different sources like Vendors, World Quests, Reputation, dungeon drops, and even rated battleground win.
If you hover over the little stars in your spellbook, you can see the source of the next rank for the selected recipe.
Leveling Legion Blacksmithing
Lightforged Draenei characters have +10 Blacksmithing skill because of their passive [Forge of Light], and Dark Iron Dwarves have +5 from [Mass Production]. An extra 5 or 10 Blacksmithing skill means recipes stay orange for 5 or 10 more points, so you can save a lot of gold by doing lower-level recipes for a few more points.
1 - 60
60 x [Demonsteel Bar] - 120 x Felslate, 60 x Leystone Ore
Make one [Rank 1 - Demonsteel Waistguard] before you reach Blacksmithing 60 while it still gives skill points. But you only have to make one to get the rank 2 recipe.
Keep all the Demonsteel Bars for the next part.
60 - 100
Demonsteel armors can only be crafted near a Firmament Stone. You can find the stone near Muirn Ironhorn at Ironhorn Enclave in Highmountain. (up at that huge mountain)
Make sure to get the RANK 3 recipe! Higher rank recipes give skill points longer. Also, the rank 3 gives 3 skill points for each craft.
14 x [Rank 3 - Demonsteel Waistguard] - 56 Demonsteel Bar, 28 Blood of Sargeras.
Rank 1 recipe
Rank 2 recipe
After you craft any Demonsteel armor the first time, you can talk to Muirn Ironhorn to get the rank 2 recipe for that armor piece. You have to craft one from each if you want to get all of them.
Rank 3 recipe
[Recipe: Demonsteel Waistguard - Rank 3] is sold by Strap Bucklebolt for 500 Sightless Eye at the Dalaran Sewers. Check out my Sightless Eye farming guide, and you can get the 500 in about 15-20 minutes.
I hope you liked this Legion Blacksmithing leveling guide, congratulations on reaching 100!
