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 Alchemy.
Leveling Pandaria Alchemy
Go to Pandaria and find Poisoncrafter Kil'zit in Dread Wastes at the Klaxxi'vess, then learn Pandaria Alchemy.
Goblin characters have +15 Alchemy skill because of their passive [Better Living Through Chemistry]. An extra 15 Alchemy 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 - 10
Pandaria Alchemy has a significantly different leveling process. The Pandaren trainers will only teach you 2 recipes. These two recipes are used to unlock additional recipes. As a result, there is no set progression in crafting for skill points.
20 x [Master Healing Potion] - 20 x Green Tea Leaf
The number of recipes you can discover is limited by your Alchemy skill. Stop making the healing potions after you reached 10 and discovered 2 new recipes. (You can only discover 2 new recipes with Pandaria Alchemy 10).
10 - 55
Make the Potion/Flask/Elixir you discovered previously until you discover more recipes.
You will keep discovering new recipes, so try to always make the cheapest potion.
You should always prioritize potions that use Green Tea Leaf because it can be found in every zone and most likely it is always the cheapest herb. Stop making recipes when they turn green if you can still make orange/yellow recipes. Only make green recipes if there is nothing more left and you still haven't discovered [Master Mana Potion]
How to determine which potions to make:
You should save around 20 each of these herbs: Green Tea Leaf, Snow Lily, and Fool's Cap. You will need them to reach 75.
55 - 75
If you didn't discover the [Master Mana Potion] recipe yet, then you will have to make the previous recipes until you discover it.
If you reached 65, and you crafted a recipe for like 15 times but you haven't discovered anything new, it means you are limited by your Alchemy skill. You have to make Flasks/Transmutes to increase your Alchemy skill.
20 x [Master Mana Potion] - 20 x Green Tea Leaf, 20 x Snow Lily, 20 x Fool's Cap
I hope you liked this Pandaria Alchemy leveling guide, congratulations on reaching 75!
