Honestly, I couldn't tell you. I maxed each character's IC skills, then 'numbered' each character. Edge was 1, Reimi was 2, et cetera. I then went through every combination by putting in characters 123, then 124, then 125. You get the point.
I made every possible recipe you can through invention in one fell swoop. Well, until someone left and I got the other two. Three fell swoops.
I just looked elsewhere and it said, Meracle has to be in all crafting recipes and that for the Travelers Cloak you need craft 11 and sense 5. So the figure out which characters have those values and use them... Dunno what else, I had no problem, but we know how that goes. --- Død og ødeleggelse til spydige tenåringer som synts at de er flinkere enn alle andre! !FC: 2148 4989 5512-Kikyo
