In this guide, you will find out where to farm for Oxium in Warframe.
You can get Oxium from a number of Corpus missions as Osium Drones can spawn in most Corpus missions. Though in some missions, they seem to spawn more often than others, the two main missions being 10 on Jupiter and the outer terminus on Pluto both being defense missions.
You can also get some Oxium from running Desdemona on Uranus, which is a sabotage mission that can drop Oxium as a C rotation reward for completing it. It is recommended to stay for at least 10 waves or longer to get it.
For the Sabotage mission on Uranus, you need to make sure that you get all 3 grineer caches in the mission to get C rotation rewards and have a chance at getting Oxium as a completion reward for the mission. But the drop chance isn’t too low, so you shouldn’t have too much trouble getting Oxium after a few runs. If you get the Oxiu C rotation reward, then you will get about 250 as a completion reward.
Oxium can also drop from breaking containers/crates in the mission as well, though the drop chance is fairly low.
