I started with 10 stacks of green tea leaf, 9 stacks of rain poppy and 1 stack of silkweed. From these 20 stacks of herbs I got enough pigment to make 100 ink of dreams and 9 starlight ink. I only used 66 inks to level my Inscription skill from 525 to 600. Depending on what recipe you choose for the last 4 skill points, you can potentially level to 600 with only 60 ink of dreams. You can get by on 16-17 stacks of herbs if you're having trouble finding spawns.
At 525 all of the Cataclysm recipes are yellow or green. When you reach 530 skill the Cataclysm recipes turn green or gray. Luckily all of the Zen level recipes are still orange. As a result I don't believe it's a good idea to make Cataclysm items for early skill points unless you are having serious difficulty finding herbs. Since the new ink recipes are still orange, it's probably best to make them. You're going to need at least 60 ink of dreams anyway, so you may as well get skill-ups while doing it. The two ink recipes turn yellow at 535, the rest of the recipes remain orange.
Assuming you're cranking out inks to use up your pigment, both recipes turn green at 540 and gray at 545. Most of the Zen recipes are still orange at this point except Tome of the Clear Mind. All glyphs and the Scroll of Wisdom are still orange. You'll probably make about 30 inks by the time the ink recipes turn gray, but you need 60+ for the full leveling process so you may as well make them. You also learn first 4 shoulder inscription recipes at 540 which are orange when learned but only grant 1 skill point. Zen glyphs are more efficient use of materials at 540 since you get 3 skill points for making them.
The Zen glyphs are locked behind a discovery mechanism on a daily cooldown. To learn a new glyph, you need to make a Scroll of Wisdom. In addition to the new glyph, you'll also receive a scroll of wisdom. These are used to craft epic items and the new Darkmoon cards. As soon as you exhaust the skill points from ink recipes, you should make a scroll of wisdom to discover a glyph. All glyph recipes are orange at 525 skill and remain so until 595 skill. Once you learn a glyph you can start making it and leveling up. Just cross your fingers that you get a good one because you'll have quite a few of them!
When you reach 560 you'll unlock the new staff and fan recipes. The two rare staff recipes and one rare fan recipe turn yellow at 570, so they don't last all that long. All glyphs, epic items and the scroll are still orange at 560. Once again, the lowest cost items to make are Zen glyphs (3 skill points for 3 inks).
When you reach 575 you can learn the four personal shoulder enchants, which give 2 skill points each. I would hold off on enchanting your own gear just yet, save this for later in the progression. At 580 you learn the upgraded Runescroll of Fortitude. It uses 10 ink of dreams and only gives 1 skill point, so it is not a good use of materials. Zen glyphs are still your best bet here, unless there's a specific item you plan to make anyway.
At 595 all of the Zen glyphs turn yellow. You can certainly continue making glyphs if you like. But if you want to maximize skill points, now would be the best time to take care of personal shoulder enchants. You can get 2 skill points for 3 inks with the "secret" recipes at this point. Otherwise you could crank out a few of the greater inscriptions instead. You should have gotten enough misty pigment to make at least 6-10 starlight ink. These recipes also give you 2 skill points, so you could get your last 4 skill points this way. If you decide to stay with the glyph recipes, it will probably take you about 5 more glyphs to reach the skill cap (an extra 15 ink).
545 - 560: 5x Zen Glyphs (3 pts each)
560 - 575: 5x Zen Glyphs (3 pts each)
575 - 596: 7x Zen Glyphs (3 pts each)
596 - 600: 5 or more Zen glyphs | 2x "Greater" inscription (3 pts each) | 2x "Secret" Inscription (3 pts each)
If you'd like to review the Inscription recipes in greater detail, including trainer locations, just visit the Crafter's Tome Inscription list. The site was just updated last night will all of the latest data. Make sure you change the settings in the "Expansion" tab to show only "Mists of Pandaria" if you want to view just those recipes. Also, the Pandaria locations aren't showing in the list view, but you can click the "More" button to see the full list of trainers.
And now, because you guys are awesome, and this guide is seriously boring, let's get out the party favors!
Sadly, the origami items despawn and are gone from your inventory after using them. On the plus side, the kites are added to your pet list and can be called like any other pet!
Special Note: There are 2 Zen glyphs that do not use the new Zen ink. One uses Jadefire Ink and the other uses Ink of the Sea. Now there's a good chance that these will be corrected before launch, because this looks like an error to me. However, if you happen to discover one of them as your first glyph, theoretically you'd be able to fully level Zen Inscription with your current ink stash. Bear in mind that there is about a half a percent chance you'd end up with one of these glyphs. And again, this is assuming they remain unchanged. But I did want to call attention to this possibility so you'd be aware of it.
