Oxium

"Oxium is a rare lighter than air alloy of Orokin origin"

- In-Game Description

Oxium is a rare component. Although dropped by the uncommon enemy unit Oxium Ospreys with a perfect drop rate, it can only be found in quantities of 1-3, though it does not seem to drop if they successfully suicide charge a player or wall and die.

Oxium can be also found in the Orokin Void by destroying containers, and as rare loot in Corpus containers.

Gathering Tips
''These tips are based on opinion and may not be true. They should be viewed as advice and not solid fact. Keep in mind that factions on nodes change over time with Invasions, so farming locations will change over time.''
 * Playing Corpus Defense, Survival and Mobile Defense missions can yield 15-30 Oxium per run.
 * Camenae, Sedna frequently yields 40-60 Oxium in 15 round defence. An Osprey spawns almost every round.
 * Kappa, Sedna frequently yields 20-55 Oxium
 * Sedna is also currently under Grineer control
 * Mimas, Saturn frequently yields 30-60+ Oxium for a 20 minute run, as well as occassional Orokin Cells and survival rewards. It's recommended to stick together to make collecting resources easier. It is recommended to run Mimas over the other maps due to it's higher oxium drop and low enemy levels.
 * Saturn is currently under Grineer control, however.
 * Thalassa, Neptune frequently yields 15-30 Oxium (15 waves, more if you stay longer)
 * Thalassa produce 2-4 Osprey every wave, (higher waves seems to produce more)
 * Having a stronger team seems to increase Oxium Osprey's spawn rate
 * Past wave 15 is recomended using Rhino Stomp or Molecular Prime to stop Self-Destruct
 * E.Gate, on Venus, can yield over 20 Oxium per run.
 * E.Gate produces 1 Osprey every 10-15m. Longer runs yield more chances to get Oxium
 * Venera, on Venus, can yield 20-40 Oxium every 15 waves. Oxium Osprey's spawn quite frequently on this node.
