As promised, I spent yesterday working on Inscription on the Test Realm. Despite a few minor glitches, I was able to get all the way to 350. Since it was still fresh in my mind, I went ahead and put together a user's guide to Incription. I've also done a shopping/recipe list like we currently have for Jewelcrafting. I'm calling it a Power Leveling guide, since that's pretty much what you have when you provide a list of ingredients and a recipe progression chart.
Right now it's not as polished as our other guides. There are no links to recipes because the recipe list on our site is kind of a mess. I need to update with the current build, which I plan to work on next. But with less than two weeks until the pre-WotLK patch goes live, I wanted to get the Inscription information out there so you guys can prepare (if you haven't yet).
The power-leveling guide includes a list of herbs and tells you how many stacks of herbs you need for each pigment. My previous estimate of three stacks per herb was mostly close or overkill, but for the 150-200 range it's a bit short. This is primarily because Blizzard didn't split up the herbs as evenly as I assumed and the fourth ink only has four herbs assigned to it, while the next group has seven herbs. Personally I think they should have evened that out a bit, but I suppose it's too late to quibble now. So for those of you who want to tweak your numbers, this should give you a much closer estimate of the amount of herbs needed.
Don't forget that these guides are based on the pre-WotLK build on the Test Realm, which can and probably will have some last minute changes thrown in before it goes Live. I ran into a bug at the 290-300 level where two of the recipes require an ink that isn't trainable until 300. This forces you to use the 285 recipes to get the last 15 points, which uses up extra herbs. I submitted a bug report, but that may or may not be corrected in time. My shopping list should have enough herbs to cover it, just in case. Once the patch goes Live I will relevel Inscription and make the necessary corrections to the guide.
