This morning I was able to push past 350 (by 2 points) thanks to a kind beta player putting up a rare gem cutting recipe for 100g. Most of them sell for 300-1000g, so this was a real bargain. Since there are easily 20 rare gem-cutting recipes at 350+, there's no way I can pay that kind of money over and over. So I was happy to see a cheapie that matched two of my gems. Right now I have a stash of about 6, so I'll still need a few more recipes to cut the others. But I cut those two with my new recipe and I should be able to sell the cut gems for a few hundred gold and plow that money into more recipes :)
Also, I got a comment yesterday from a reader who asked about whether there are levels involved in Prospecting, and if it's possible to disenchant Jewelry. Both very good questions and ones I haven't really touched on, so I'm going to address them here for the benefit of all.
Prospecting: Yes there are levels. When you first learn prospecting you can only use it on copper ore. I'm not actually sure where Tin kicked in because I didn't have any, but I'm guessing it was probably around the same point that I started training bronze recipes. I was able to prospect iron ore right about the same time I got the iron recipes, same with thorium and fel iron. So you can probably assume that when you receive your first recipe, you'll be able to prospect that ore.
I found this chart on the Giddy Gamer that has specific numbers, but I can't really say for sure that it's accurate. It looks to be close, although I was able to prospect adamantite before 350, I think closer to 330 or 340. The thorium number looks too high also, I would guess it's closer to 225 when you get the thorium setting recipe.
As for disenchanting jewelry, I don't see why not. I haven't actually tested this but I'll be happy to do so. I have a ton of jewelry that isn't moving quickly anyway, so why not? I'll get back to you guys on this one, but I expect it will be disenchantable.
