Okay so I'm looking at the MB and I see the Rainbow Crafting gear set, level 53. HQ stats look quite good, but I don't seem to have the recipes to make anything other than the torso.

where do these recipes come from? I never bothered to do the Master II books for any of my crafts, tho I did get the Lucis tools. If I have to go backhand do these I will, I just want to know
