Demiatma drop rates are unacceptable

not going to add to the fire here, but I have been incredibly unlucky with my drops - actually 0 in a few hours' playtime. Abandoned the quest and restarted it, hoping this helps my drop rate.

I've spent several hundred hours playing Fates on OC and still don't have all the crystals for a relic weapon...
Especially for the "Malachite Demiatma," it took me more than 80 hours to get one...
