Here are a few tips I can pass on from my experience....I hope this helps! Never stay in an area too long. Every time I left an area and came back I got atma within 20 minutes of doing so, don't know if it was coincidence but it worked for me. Also got all my atma solo. Tried a party once and stayed for 6 hrs. left went to a new area solo and once again, within 20 minutes atma.
