The reason I feel this farm is so efficient is because you are farming for two different sources of platinum simultaneously. The Horend, Deimos Corrupted Mod and Smeeta Kavat Platinum Farm

If there’s three new warframes in your foundry you need 120 platinum just to reach max mod capacity and buy new inventory slots for each of them.

You need platinum for so many things in this game orokin reactors and catalysts as well as inventory space for weapon, warframe, companion weapon slots, and even riven slots all cost platinum. I ran some tests and have some data to share about Horend runs, and I plan to share my methodology in the hope of helping newer players to start accumulating platinum. Horend corrupted mods + Smeeta Kavat imprint grinding is the best plat farm I’ve found in the game so far. To this end, I think I finally have a decent answer. It’s just about picking which grind is most efficient. Paradoxically, skipping the grind requires a grind. My favorite thing about warframe is that you can farm platinum and buy pretty much whatever you want which bypasses a lot of grind. Im just an average MR 15 player with too much time since the pandemic and a deep curiosity and hunger to farm myself rich on platinum.
