Often the materials are based on a case that you will gain one skill point for each craft. This won't happen, so you will have to buy a few extra materials while you are leveling your Draenor Inscription.
Learning Draenor Inscription
You can learn Draenor Inscription from the Draenor Inscription scroll.
There are three ways to obtain this scroll:
If you build a Scribe's Quarters at your garrison, you can buy the scroll from one of the NPCs at the building. Complete the "Your First Inscription Work Order" quest first, or the NPC won't sell you anything. (You also must learn Inscription first from any Inscription trainer)
If you are still leveling your character you will probably get a Mysterious Satchel (Alliance) or a Illegible Sootstained Notes (Horde) from Draenor mobs. Both these will start a small quest chain and the reward for that quest is the Draenor Inscription scroll.
Approximate Herbs Required
Cerulean Pigment comes from milling any Draenor herb.
You will get 2 Cerulean Pigment from Milling 5 herbs, and you will need 900 Cerulean Pigment, so you will have to mill around 2250 from these herbs:
- Nagrand Arrowbloom
- Talador Orchid
- Gorgrond Flytrap
Leveling Draenor Inscription
1 - 25
Milling herbs gives skill points up to 25, so you can reach 25 by simply milling your herbs.
Nightborne characters have +15 Inscription skill because of their passive Ancient History. An extra 15 Inscription skill means recipes stay orange for 15 more points. You can save a lot of gold by doing lower level recipes for 15 more points.
25 - 100
You can buy the Virtuoso Inking Set and Light Parchment at Ashran from Jasa (Horde) at Warspear, or from Trader Caerel (Alliance) at Stormshield. (or you can buy them at any other major city like Orgrimmar or Stormwind, ask a guard where the "General Goods" vendor is located)
Create one Secrets of Draenor Inscription and buy Technique: Volatile Crystal in Ashran from Joao Calhandro (Alliance) at Stormshield, or Maru'sa (Horde) at Warspear. (you can also buy it at the Scribe's Quarters in your garrison)
75 x Volatile Crystal - 900 Cerulean Pigment
An alternative way to level
There is an alternative way to level, which will cost a lot fewer Herbs (1250 instead of 2250).
There are several NPCs that can randomly spawn in your garrison each day. They will appear in the entryway of your level 3 town hall, they won't spawn in lower level Town Halls. There is a set rotation of profession traders for each day:
Ore -> Dust -> Fur -> Leather -> Herb
Everyone on your realm will have the same trader if they get the trader, but it's not guaranteed that you get a profession trader in your garrison, even if it's the day it is supposed to spawn because other quest givers can also spawn. Basically, one NPC will spawn out of 4 and there is a chance for that NPC to be a profession trader.
You will want to get the Herb traders Samantha Scarlet (Alliance) and Nicholas Mitrik (Horde) because they sell the Technique: The Spirit of War which you will use to level Inscription. If you click on the NPC links above, it will take you to wowhead.com where you will see a small box on the right with the title "Quick Facts". There you can see two dates, those are the dates when the Herbs Trader can spawn in your garrison. (for some reason the dates are currently swapped, so if you play in Europe, use NA dates, if you play from NA, use EU dates)
If the Herb Trader didn't spawn, then you have to wait another 5 days, or you can still try using the trader at someone else's garrison. Ask your friends/guildmates to check which NPC they got. Then have them invite you into a group, and then right-click your own portrait and select "view leader's garrison". This will take you to their garrison, and you can use the Herb Trader if they have it there.
- 25 - 100
75 x The Spirit of War - 75 x Primal Spirit, 300 Cerulean Pigment
Primal Spirit is also sold by the Herb Trader for 5 Gorgrond Flytrap (Horde) / 5 Frostweed (Alliance), so you will need 495 from one of these herbs. But, if you played during the Warlords of Draenor expansion, then you probably have hundreds of Primal Spirit in your bank, so you can save even more gold because you don't have to buy any of them.
I hope you liked this Draenor Inscription leveling guide, congratulations on reaching 100!
