I have been looking up recipes for equipment I would like to craft and on the wiki a few things (the jelly helm and shield in particular) didn't have a vendor listed that sells the recipe only the item its self. And when I looked up a list of items that you cannot craft neither of these were listed.
So basically I am asking that if you cannot buy the recipe but it isn't on the uncraftable list how do you craft these items? Does this mean you have to go to the vendor you meet at the terminal? Or is it possible to find them as a drop on a floor?
The Jelly Helm and Shield are definitely craft-able. All recipes can be found at the terminals in the clockworks, and this is usually the best way of finding the recipes you want, as they switch every time to get to a terminal. However, the recipe vendor in Haven switches out recipes every day (usually 1* or 2*), and I swear I've seen a jelly recipe in there, myself.
Also note that the wiki may be a bit outdated, as a lot has changed over the past couple weeks and the edits are still catching up~!
