Corrupted Holokeys are one of the many kinds of resources players can farm for inWarframe. It has a somewhat niche use, but even so, it’s a valuable resource for players who want to special Tenet weapons from the Perrin Sequence.
Farming Corrupted Holokeys is going to take a lot of patience and dedication. They aren’t as plentiful asother resources inWarframe, and unfortunately, players will need hundreds of these if they want to collect all the Tenet weapons. This guide covers the best spots to get Corrupted Holokeys, as well as some tips on how to farm them more efficiently.
Warframe: Corrupted Holokey Farm
Corrupted Holokeys inWarframedrop fromEmpyrean Void Storm missions, which means players will need a Railjack in order to get them. These are end-of-mission rewards, so you don’t need to worry about potentially missing them.
Any Railjack mission with an active Void Storm can potentially reward players with Corrupted Holokeys (about 90% of the time), thoughthe most efficient missions to run seem to be those on Pluto and Neptune. Any mission type can drop Corrupted Holokeys, and which ones you pick are up to personal preference.Skirmish missionsare easy to complete if your Railjack is strong enough.
The amount of Corrupted Holokeys you’re able to get per mission is fairly low, but since you’re in a Void Storm mission, you’ll also becracking open Void Relics as you farm, giving you the opportunity to get Prime parts. Also, you can sell any unwanted rewards for tons of Endo, which you can use to level up your mods.
It’s worth noting that Corrupted Holokeys are not affected by resource-boosting effects. Additionally, defeating a Sister of Parvos will reward one Corrupted Holokey for every member of the party.

What are Corrupted Holokeys For?
Corrupted Holokeys are used to purchase Tenet weapons fromPerrin Sequence’s Ergo Glast, who players can find in any Relay. Tenet weapons are modified Corpus weapons usually carried by Sisters of Parvos. Ergo Glast sells some of these Tenet weapons for 40 Corrupted Holokeys each, albeit with a few cavets:
The good thing about the Tenet weapons sold by Ergo Glast is that players can purchase them regardless of their reputation with Perrin Sequence. Even if Glast regularly sends kill squads to get you, he’ll still accept your Corrupted Holokeys if you try to buy weapons from him.
