do 2x guardian mission, run 4-8x aahm, maybe some other crap and you already have 36k in ~4h(depends on aahm clearspeed/consistency). thats normal more or less. Unless you play the broker game.
AAHM has shit rewards it doesnt give any profit, tbh it only makes you lose gold. even if running normal 20minute run, i got 90 AAHM clear and i think i only saw 5 diamonds in them, and nothing else more interesting tbh RKEM had way more better loot before stupid loot nerf.
