Does difficulty determine which rare you get like in the first one (Shouren can only be found under Ultimate Dorphon Route for example).
Or can I take a character into normal, beat it, and perhaps get a Gratia (which is what I'm interested in). Thx in advance.
P.S. I may just hunt one with my skyly but they get it from very hard Girtablulu. I do know a quest that can find quite a few Girts but it's not exactly easy.
