Which weapon?

[Judge_Xero]

Sounds Random but, because you already have those melded Ringbands with Magic Crit, and you have super high Magic Accuracy, you should try using the Aubriest's Whisper + Acc Food for Garuda

Magic Accuracy : -20, Magic Crit Potency : +120

It would be cheap to try it out. With 200+ Magic Crit Potency it may actually do good damage.

Get a couple HQ Black Pearl Rings for the Acc + Crit Rate

Could be an interesting build.

For a basic solid build -
Get those melded pants, Woolen Tights + Materia X 2
HQ INT Rings (total 36 INT)
Buttons in a Blanket

Sounds like maybe that other guy had a better rotation too....might be another option to look at
