Well, I haven't actually tried it, just made the build on twdb thinking it fits my needs.
Some of the items shown are not needed to succeed with this build, since the image shows the "top items" rather than the "necessary items", so they are the best items for a job or a group of jobs, but there are others that can be used though with a lower amount of LP.
The AP/SP are the ones achievable for a 1 year adventurer, having done all the quests, including holiday ones.
Also, the female sets should be traded for their male equivalents. Someone said earlier in this thread that the male gender can achieve more LP so it is definitely not the best full jobs build out there.
*edit* As said while you were posting Fafer, the items in the image are the "top items", not the "necessary items". TWDB can only show it like that unless you printscreen all clothes combination for a specific job and that would be an insane amount of work. The items you refer to such as the dinner, scalp, harmonica, Inno are not needed for this build though they are the best items at some jobs. I had this build made before I had those items and though the LP were smaller, I could still do all the jobs with it. As for the FMS I agree, I guess I could adjust it now I have those new items.
