Completely solo self-found?
I'd say the best way would be to start with a FO & try to farm one person mode episode 4.
Maybe run Pioneer Spirit & let the NPCs carry you...
The sooner you can find level 1 rafoie/gifoie the better, then you can farm the first few waves of MA4A to fund your mag.
In multi I just gif, or you can run behind and sns hell jcutter, works rly well if they're frozen, ESPECIALLY on Satellites
Solo your best bet is probably just megid or excal NNH
