GU36 added the often-requested ability to reset your tradeskill choice. But what does that mean, exactly, and how do you do it?
Basically, you speak with a specific NPC and are giving the option to be reset back down to level 9 artisan. This will allow you to select a new level 10 crafting choice.
The NPCs that can help you with this profession swap carry the title of "Tradeskill Career Counselor" for most places. In Gorowyn, however, they are called a "Tradeskill Classification Advisor." They can be found in Ironforge Exchange (NQeynos - Fidelia Recolo), Coalition of Tradesfolke (WFreeport - Jonak Harvester), Tunare's Pages (Kelethin - Amy Recolo) as well as the crafting areas in Haven (Kit Breanut), Neriak (Vier N'Vul), Gorowyn (Salviln Grau`tuz) and New Halas (Padraig McDougal).
The warning text from the NPC can be a bit daunting, as they tell you that you will lose "all" your recipes and such, so Domino was kind enough to explain in a bit more detail in the forums:
Here's what happens when you confirm you want to respec:
So ... note that in #4 I specifically said primary crafting class skills. This means those oddball skills that used to be used for making interims remain (geomancy, etc.) and THAT means that the recipes from quests like "The Nest" are NOT removed from you. The higher level skills of those types WILL be removed however so good luck making something in The Nest at level 9 ... but you can certainly still try. :D
Heritage quests are also not removed. The Polished Granite Tomahawk, Manastone, and Stein of Moggok recipes are all 45 skill so aren't affected. The Wyrmslayer and Phylactery for the bone-clasped girdle do not use the primary crafting class skills so they also stay.
You DO lose class-specific recipes such as the armor recipes found in Deathfist Citadel or Emerald Halls. If you decide not to be an armorer any more, well, you don't get to make armor any more!
Recipe books requiring the "tinkering" or "transmuting" skill do not get removed, so if you're a transmuter and you have a bunch of transmuter adornment recipes, you keep those. However, if you're a jeweller and have a bunch of jeweller adornment recipes, you DO lose those since you're losing your jeweller profession.Hope that clarifies everything!
