Post what synthing arcs you find here. The criteria is that you have at least three layers. My example is Fishing > Culinary > Goldsmithing. You cannot purchase anything for the arch to be valid, other than the tools you need like a fishing pole etc. Crystals are exempt.
So this is what I did. Level up fishing to around level 12, and then used the majority of the fish I saved up in Culinary. This gave me a result of Sea Sand. Next I equipped Goldsmithing tools and and changed the Sea Sand into Fine sand. Results so far:
Fishing 12, Culinary 10, Goldsmithing nearly 6.
Total cost = cost of tools
Final result is for crystal splitting or whatever for Alchemy rank 16.
