My FC has 4 airships, I sent them to sector 6 and 13 mostly to try get the Dravanian Mote to finish up the moogle house skin. So far no luck, it seems to be a rare item... Sector 21 gave 4 Wind Silk. Sadly that's all I have to report for now. I'm quite annoyed by the rng bottleneck of needing to get items and Diadem unlock. Good luck grinding and keep the reports coming guys!
