Which Atma NMs Can Be Soloed W/out Initial Atmas?

What I mean is: which NMs could be soloed (I have a 90 dnc/90blu as well as 90 bst) without using atmas? I don't have any as of yet, but would like to solo some if possible, I can get a group if absolutely necessary, but would be cool to know which nms I can just kill on my own anyway.

Also, if I have to farm for the pop items, which ones am I looking for? And what are targets in that specific zone which BST/DNC/BLU can solo effectively?

The correct answer is: get basic atmas.

All the atmas that really matter I doubt you can solo let alone solo without any basic atmas. Even if you do solo kill the NM, you'll need to proc red!! for any real chance at obtaining said atma. Not only that, but people hate being cockblocked by a soloer who takes 30-60 minutes to kill something that normally would take 5 minutes.

Best bet? Join a pickup group in Jeuno or befriend a couple people who will help you out.
