I've been buying "Improved" and "Greater" tier components from merchants, especially the blacksmithing merchants in Rathir. I was hoping that once I got to the eastern continent I could find a merchant that sold "Master" tier components. However, there doesn't appear to be a merchant of this type in Mel Senshir, and the other couple of places I've come across (mostly Fae encampments) don't have them either.
Is there anywhere in the game I can buy Master (or better, if it exists?) weapon and armor components?
