literally all you have to do to make money this league is get a tab full of heist rings roll them for t1 recoup and a t1 res using alt spam + annuls or harvest, isolate those two mods on a rare then mist them and some gook will buy them for anywhere between 60-110 div if cogwork and upwards of 200-250 if helical
literally has like a 2% chance of "failing" because 2 positive is the fail state
with mists inclining in price you can probably make even more. i was making close to 1 mirror per day and i would only craft rings for 2-3 hours. i would track my spending and 500 div of supplies would consistently return 1200-1300 worth of rings, even on some of my extremely unlucky runs where 3 out of 5 helicals bricked in a batch of 5 helicals and 10 cogworks i still made 400 div of profit
