PROFESSIONS There is now an Apprentice Crafter and Gatherer near the Crafting Orders vendors of Valdrakken. Adventurer's who have fully specialized into their professions can trade in excess profession knowledge for Artisan's Mettle.The new NPCs Apprentice Crafter and Apprentice Gatherer are just slightly south east of the Crafting Orders pavilion in Valdrakken. If players have at least 1 maxed out profession specialization, the NPCs will have a vendor option that allows you to convert 10 profession knowledge into 25 Artisan's Mettle.
