Eiyuden Chronicle: Hundred Heroes

For those who are wondering how to get the workshop, you need your HQ to be at Level 3 to unlock its drafting studio panel. Then, you need to go find and recruit Syd, who is standing near the smithy in Hishahn. He only joins once you've met this condition.

Building the workshop itself requires platinum ore (Seaside Cavern) and Excellent Lacquer (Eldroad; Dappled Forest third area), which you can also get passively from guild missions. Most of the cheapest things to build require mystic lumber (Dappled Forest second area) and iron ore (Abandoned Mines). So you should expect at the very least to be about two-thirds of the way through the story.
