2 stars recipe

[Reika]

Can you double meld IV craftsmanship on the body and offhand without wasting? Just finished my full HQ set for gsm and need to pump in the materia to do 2 stars. I have control on my accessories right now because doing that made all of my crafts able to do 1 stars. I guess now I'll be making new ones to pump with craftsmanship. What are the caps on the accessories? I'm using the aetheryte rings, red coral earrings, militia wristbands and electrum choker(didn't see any better gear than this while browsing recipes).

I have tripple +6 craftmanship in my HQ militia Pliers.
