Top Deck Passage 2 farming. Just stand in one spot with Sol Janus Dusk and put your fountain on the platform on the bottom right. Should work for more classes besides WA if you have some skills to throw around. Afterwards there will be a 6 minute BA with lvl 10+ Sol Janus Dawn and one with below lvl 10 Sol Janus Dawn. The last one seems to be a bit less reliable to get good rates on since you will miss a few mobs on the top right or in between.
0:00 Sol Janus Dusk
7:00 Sol Janus Dawn lvl 10+
13:42 Sol Janus Dawn below lvl 10
