I don't know what's the Kupo Knight thing is all about, but I know Artisan will hide all recipe. I was leveling archer and wanted to buy a Oak Composite bow made, asked the carpenter they had, willie markeet or something. He is selling it for something ridiculous like 1mil. I asked some other carpenter on the server, non of them had recipe. So I asked willie if he could give me recipe he said only if I find a recipe he doesn't have. Now I don't have carpenter leveled so how do I possibly find out something he doesn't know? I looked on line for the recipe, and in the comment section of the Oak Composite bow I saw this:
