I have been noticing since farming relic materials, the ability material omegas (the yellow ones needed for zeta abilities as well as other character abilities) have either been dropping. Its my current bottle neck as I have to decide to save them up for a zeta ability or use 5 of them on a characters ability. I almost use all my refreshes on the relic mats everyday and I feel I get zetas way more.
Today I took a snapshot on one of the newer nodes after 26 refreshes
Is the drop rate really low? I can keep better data for a week and see but like I said, I have seen 0 the last few weeks.
