I pretty much bumbled my way through it entirely on the Japanese servers and I can't even figure out how to do what I did on it.
General questions are:
How do you upgrade/enhance your weapons? The thing I primarily used crafting for when I played on the JP Server is for upgrading my Rosa Crane to get it close to my Rod (which even at max +, it would never get close otherwise) as it was my favorite Tailis, but I can't find any option to do that here.
How to unlock higher levels for Technique/Photon Art customizing? I only have 1 or 2 for a lot and no matter how much I've crafted, I can't seem to unlock 3 or other options. Is there a particular order I need to do? I just don't want to waste a bunch of my disc fragments if I'm screwing everything up.
