I've heard conflicting reports on what, if anything, affects Empyrean item drop rates. Specifically I was curious about Iron Plates and other items required for the Daurdabla. I've heard people say nothing affects it, while I've heard others say grellow and/or blue help.
Does anyone have any legitimate proof on whether they do or do not? Our group has proc'd blue and grellow on as many of these mobs as we can, but I haven't really been able to tell anything conclusively either way. Thanks for any input!
