Armorsmith training?Follow

Check "Trade Skills - by Trade" in the column to the left - clicking on Blacksmithing will tell you all the available recipes, and if you click on the plans it will tell you where the plans are available. I haven't made it up that far yet, but from exploring the site, it appears that a number of the upper level plans are quest rewards while some others can be bought from vendors if you can get to the right people. I don't believe any besides the first two can actually be learned from an armorsmith trainer.
