Often the materials are based on a case that you will gain one skill point each craft. This won't happen, so you will have to buy a few extra materials while you are leveling your Pandaria Inscription.
If you are low on gold, I recommend you to try this Gold Making Guide, it can help you to make loads of gold.
If you are still leveling your character or you just started a new alt, I recommend you to use a leveling guide. You can level your character to level 120 in 8 days with this guide.
Approximate Materials Required:
Mill around 660 from these: Desecrated Herb, Fool's Cap, Green Tea Leaf, Rain Poppy, Silkweed, Snow Lily
Leveling Pandaria Inscription
Go to Pandaria and find Lorewalker Huynh in Vale of eternal Blossoms, then learn Pandaria Inscription.
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.
- 1 - 20
165 x [Ink of Dreams] - 330 x Shadow Pigment
You should make fewer if you mill your own herbs, because you will probably get a lot of [Misty Pigment] from Milling, and you can use them in the next step, so you will need a bit fewer Ink of Dreams.
- 20 - 70
50 x [Research: Ink of Dreams] - 150 x Ink of Dreams
- 70 - 75
5 x [Secret Crane Wing Inscription] - 15 x Ink of Dreams
I hope you liked this Pandaria Inscription leveling guide, congratulations on reaching 75!
