I got lucky with my atma. I spent 3 weeks getting 3. And that was constant fate farming. Then one day, I get one, kept going, and ended up getting 8 in a single day. Got the last one the next morning. I was thinking about just skipping atma and going soldiery, but I kept at it.

Look for fate groups in the area. They help. It's always more fun with more people. By myself was horrible.
