I don't have the recipe books to make the mosshorn earring, rose gold choker, or dodore belt, & have been trying to do this without buying finished products or anything I can't already make on my own (like demimateria - which is gonna be a whole OTHER source of gil woes to level THAT up). I've already dropped 600k gil on materia, & still haven't come close to max overmeld on the pieces I have; I don't even have enough gil left (750k-ish) to do it all (especially w/ normal failures on overmelds).

With all of that - is there ANY rotation that can get me to a reasonable (say... 70+? 80ish?) percent chance of success on vanya silk? I'm just about ready to quit crafting I'm so discouraged, & it's been a major source of enjoyment in the game for me until now.
