The Corrupted Holokey is a type of currency you can earn in Warframe in some of the later-game content. You’ll definitely need to get several dozen of these if you want to get the extended arsenal of the Tenet weapons.
How to get Corrupted Holokeys in Warframe
To get Corrupted Holokeys in Warframe, you have to play the Void Storms missions that work the same way as Void Fissures. These take place in the Railjack portion of the game, rotating between the six Proxima regions. They have a chance of being given to you at the end of a mission.
Most missions will consist of either a typical mission you’re used to in the regular game, with Skirmish and Volatile being the Railjack-specific ones.
Just complete these missions like normal, maintaining your Railjack and preventing it from getting destroyed. In these missions, though, you will have to fight enemies on foot, wait for them to get corrupted by the Void, and get ten reactants.
Depending on the Proxima region you’re in, you can get a different number of Corrupted Holokeys. These are the amounts depending on the Proxima:
| Region / Proxima | Holokeys earned | Drop chance |
| Earth | 3 | 37.5% |
| Venus | 3 | 37.5% |
| Neptune | 4 | 36.59% |
| Saturn | 5 | 36.59% |
| Pluto | 6 | 37.5% |
| Veil | 10 | 37.5% |
While getting Holokeys isn’t guaranteed every mission, you do run a decent chance of getting some for every three missions.
You can also earn Corrupted Holokeys after vanquishing or converting a Sister of Parvos, but you only earn one per Sister, so it isn’t too viable.
Best Corrupted Holokey farm in Warframe
The most efficient Holokey farm in Warframe would either have to farm the Veil Proxima missions or Exterminate missions in any region.
The Veil Proxima missions have the biggest payout of Holokeys per mission. They are also the toughest and typically longest to complete. So, unless you have a dedicated team to farm with you or a really good solo loadout, this is hands-down the best method.
The other Corrupted Holokey farming method would be to look through the Void Storms menu and look for any Exterminate missions. It does not matter which planet it is on. These just go the quickest in terms of objectives out in space and on foot. The payout may not be as high as a Veil Proxima mission, but you’re still going to be earning keys at a good rate.
