This hread should be your one-stop-shop for low end crafting advice. I'm guessing the Original poster took off as it's not updated with 4* Info, which is too bad. Anyway, depending on which exact synth you are doing at 1*, there are lots of different factors. The poster in the thread I below, notes the Durability, and the difficulty of the synth you are attempting. These are things you need to know before asking about these synths. 1* have a lot of different combinations. The hardest ones you probably just can not do with low CP.
