What is your Atma Drop Rate & Farming Method

[VeyaAkemi]

I have now finished the Demiatma step, for the last two Atmas, I decided to go for Kozama'uka FATEs, it's something that I perhaps shouldn't have done, considering I still plan to do a LOT of Occult Crescent, but I was so close that if I didn't do that, it would keep burning me at the back of my mind, so I thought best to rip the bandaid, took me about 3 hours to get the two I was missing, not much to be said about it, some people were there at first, but fewer and fewer as the night went along until I was alone, it's about what you'd expect from FATE farming, and what is done is done.

Now, what am I supposed to do with these...? kinda feels bad to just throw them out considering how rare they are, but I suppose it's all I can do?
