Apothecary farming

Hello fellow Exiles! Lately I have been running Crimson temple and Defiled cathedral hoping to farm mageblood for myself to this point I have did close to 400ish runs mostly on crimson temple but have never seen apothecary drop yet in general my rng was so bad Im feeling discouraged to continue my farming Im not sure if im doing it right way but my atlas specs on harbinger lockboxes and full breach with added 5+ to lockboxes +3 harbingers and and 150% divination scarabs All i got from this was like 4 enlighten and maybe 5 bad luck cards and loads of currency so I managed to build a decent lightning arrow build that clears maps pretty quick I would really appreciate If someone can point me to the right atlas build or strategy.Thank you for your time.
