How do i push towards 4 star?

[Xenosan]

I have not done the math or intend to, but that gear with supra and the new off -hands melded should make you a 4* capable crafter.

I can verify this. With Supra, max melded craft-specific gear and BiS jewelry (jewely/belt are only 3star), and an OH artisan tool (again only 3star) with +15 craftsmanship & +7 command melded meets the exact stat requirements needed to 4 star.

No food or fc buffs needed. Bouillabaisse it is. (should put you at 395 cp after eating)

If you can HQ the 3.9star token items for the master2 book, you can HQ the 4stars with a very similar rotation (substitute Rapid Synth gambles for pbpx2 + careful synth x3 for progress)

edit:

This is the route you have to go if you intend to craft the BiS left side gear yourself instead of buying off MB. I suggest NOT doing what I did and starting with leatherworker first, as the artisan's mitts are the weakest upgrade it seems. (all that work for just +4 control)
