How do i push towards 4 star?

You can reach the magic 453 craftsmanship number (lets you finish 4★ progress in as little as 5 steps, 3★ with 4 steps) and 407 control with full melded artisan & Demimateria acessories, supra and an artisan offhand melded with 3cp/3craft/3craft

The artisan mitts can be opted out for the ixali smithing gloves instead, but you are missing out on CP.

If you'r short on craftsmanship, use chilled popoto soup or shark fin to get some extra CP in there as well. Otherwise, try to meld yourself to 407 control (theres no food that gives both control + CP)
