Best way to farm Orokin Vaults?

So long story short, I need the Blind Rage mod for almost all of my builds to go into the higher end Steel Path stuff that I wanna do, and being a broke college student, buying it with plat is out of the question. So I gotta farm some Orokin Vaults for that bad boy. Is there an optimal way to farm Orokin Vaults? Things like Frames, weapons, strategies? I get the base idea on how to farm them, but I don’t know the best way to do so with limited time. I really appreciate any advice u guys have! Thanks!
