The problem with using low-level fodder like this is that you also have to use leveled fodder for the first batch. This increases the cost of the second batch, since you're synthing a higher level accessory (39 instead of 32). I don't have an issue with not being able to level accessories fast enough, as I don't have enough accessories worth leveling in the first place, especially SSRs. For my last SSR, I used the following recipe:
SSR 1-50
20 SR1 to LV32
8 same-element SR20, 7 same-element SR25, 3 same-element SR23, 2 SR20
66000 gems
That uses 18 same-element SRs, which takes 3 weeks of AQ4 to farm. That's faster than I acquire good SSRs worth leveling. I auto AQ3 with Mordred. Haven't tried with D'art, but it's worth a shot I suppose.
