Something to note, you can find your own recipes as well: I have some of that elemental material so I can make new recipes simply by trying to make like the iron saber and adding the elemental stuff for the aqua sword. This works for many of the weapons where I am getting gaps, like I have technique 1,3, etc. So 2 is often an elemental version of 1.
