Thanks for nothing SE on 3 star crafting!

It is still dependant on RNG, like you said, but with practice (and actually by adding more RNG based skills/decisions), you can lower the RNG's impact, if that makes any sense. I.e. greater risk - greater reward and ofc can still Reclaim if needed.

I did use the new offhands for some of my crafts (as it does make it easier), but in that first day it took a while to get all the sealants to craft them all and I was in a rush! xD

You pretty much need the new offhands in order to actually make 4* items, so really no reason not to use one these days when unlocking the master 2 books.

I suppose you used 3 Rapid Synthesis and Byregot without SH?
