Where do I find Orokin Cells post-Specters of the Rail?

[exfahim]

I don't know where to find Orokin Cells, need plenty to farm for a while since I got some completed Prime Weapons.

Kill Sargas Ruk on Saturn.  Do any excavation or survival on Saturn.  With that last one, you can replace "Saturn" with "Ceres" if you want higher-level enemies.

Does that include dark sector missions?

[Arkvold]

They're planetary drops - they can drop from any enemy or container on the planet.

Sargas Ruk doesn't seem to drop Orokin Cells anymore or the drop chance has been significantly reduced, it used to be that you can get at least one for every two runs, oftentimes more, but right now I've been getting only Detonite Ampules and Plastids even after 10+ runs.

Do Titan, on Saturn:

[-CCC-Secret]

Phorid on any planet that drops Cells. Lephantis.

Or you can go full on farm. Bring Nekros, Pilferoid, Speed Nova and maybe EV/Ore Gaze Atlas or Ivara. Also bring a Smeeta. Like I've said before, although it's been nerfed, it's still useful for 'rare' resource farming.
