Boy is it expensive! I've spent about 200K just getting my skill up to 100. Luckily, some of the things I make sell very well, and I've been able to keep working on skilling up and not run myself totally broke!

I think posting raw mats + the vendor items you need would give everyone an idea of what to bring. I know for me to make 1 silver accessory (the basis for all rings and earrings), it costs about 1500g, not to mention the vendor items used process gems, etc. I'm sure it's the same for all the professions (except cooking, which I find to be super cheap).

I have a post in the crafting thread that I will probably update later tonight with mat costs.
