āIt is done. Operation: Plague Star is no more.ā
This event has concluded on all platforms.
Operation: Plague Star is a recurring event introduced Update 22.3 (2017-11-15), where players are tasked to destroy an Infested meteorite that crashes in the Plains of Eidolon, with its passengers threatening to overwhelm both Ostron and Grineer alike. On the PC build, the event originally began on November 15, 2017 and ran until November 27, 2017.
Unlike most events in WARFRAME, Operation: Plague Star is a recurring event, with the Infested "boil" regrowing every several months and the Tenno are called on to cull it once more.

Event Synopsis
Rally your Squad and defend the Plains of Eidolon!
A mysterious meteorite has crashed just outside of Cetus revealing a horrific boil. The boil is growing and the Ostrons have sighted Infested life forms emerging from it. We need to act now before they make their way to Cetus.
Konzu has received reports that Vay Hek possesses a toxin that can destroy the boil. But Vay Hek wonāt help; he sees this infested boil as a means to rid the Plains of Cetus and the Ostrons.
We need to obtain a batch of the toxin and destroy the boil before it becomes unstoppable. Visit Konzu in Cetus to learn his plan for retrieving the toxin from Vay Hek.
What You Need To Do
- For the duration of the event Konzu has a specific Plague Star Bounty where players are tasked with stealing the Toxin from the Grineer and using it on the boil. The Bounty is divided into four phases;
- First, players must raid the Grineer's Thrax Toxin storage, which is located in one of the various Caves that dot the plains. The Toxin storage unit is shaped like a triangular prism and is generally located at the far end of the cave.
- After acquiring the Thrax Toxin, players must head to a Toxin mixer, which will spawn in an Armored Vault in a given Grineer outpost. Once the Toxin is put in the mixer, players must then defend the mixer for 3 minutes from Grineer troops.
- During the mixing phase, players may opt to add either Eidolon Phylaxes and/or Infested Catalysts, increasing the Standing reward from the bounty in exchange for increased difficulty later on. Up to 4 of each can be mixed with the Toxin.
- The blueprint for Eidolon Phylaxis is purchasable from the Operational Supply Syndicate, which is available during the event, while the blueprint for the Infested Catalyst is available from Clan Bio Lab Research.
- Once the Toxin is mixed, players are instructed to head to a downed Grineer Drone which will deliver the Toxin to the boil. As with Drone Hijack missions, players must defend the drone from Grineer and Infested attackers as it travels to the boil.
- When the Drone reaches the boil, the boil responds by spawning Infested to defend itself. Here players must thin out the Infested horde while the Toxin poisons the boil, with a percentage gauge denoting their progress. The decisions made during the Mixing phase affect the difficulty of this phase;
- For every Eidolon Phylaxis mixed with the Toxin, both the density of the Infested and their level range increases, up to level 30 if 4 Phylaxes were added.
- For every Infested Catalyst mixed with the Toxin, a Hemocyte will spawn at specific points, pausing the percentage gauge until players defeat it. The Hemocyte can spawn up to 4 times if 4 Catalysts were added, with its level(s) affected by the presence or absence of Eidolon Phylaxis. Check its page for more details.
- Once the gauge reaches 100%, the Bounty is completed, awarding a variable amount of Standing based on how many Eidolon Phylaxes and/or Infested Catalysts were mixed with the Toxin. Players are free to remain on the Plains, return to Cetus or visit a bounty tent to undertake the mission again.
What You Need To Know
- Throughout the duration of the event, the Infestation will spawn on the Plains of Eidolon regardless if the player is doing the Bounty or not, and will attack nearby Tenno, Grineer, and even the Eidolons during the night.
- The Infested will consist solely of Chargers, Runners, Leapers, Volatile Runners, Ancient Disruptors, Tar Mutalist MOAs, and Mutalist Ospreys carrying normal Crawlers.
- Infested Spawn Pods, much like the ones spawned by Boilers, can be found throughout the Plains, either on the Plains as is or falling from the sky.
- The boil deals heavy Script error: The function "Proc" does not exist. damage to any Tenno standing on or even flying close to it, so players are advised to stay away from it as much as possible.
- In the event that a player does get knocked down from the boil's damage, it is recommended to use a Revive instead of someone risking a rescue, as the damage may bring the rescuer(s) down as well.
Event Rewards
- The base standing reward is 1,000. An extra 250 is rewarded per Eidolon Phylaxis and 250 per Infested Catalyst mixed into the toxin, for an additional 2,000 standing points and thus a maximum possible standing reward of 3,000.
- Unlike most events, players can select their Operation Rewards through the Operational Supply Syndicate, which is only accessible from Nakak during Operation: Plague Star. The Syndicate has its own rank system, and players can spend the Standing gained from the Plague Star bounty on the following rewards;
| Rank & Title | Sacrifice | Benefits | Standing (Minimum to Maximum) | |
|---|---|---|---|---|
 3 - Champion |
10 Script error: The function "Resource" does not exist. |  20,000 3,000

- Any Syndicate progress from a previous instance of Operation: Plague Star will be carried over to future reruns, so players need not worry about regaining Syndicate Ranks.
- This Syndicate has no daily standing limit.
- On defeat, the Hemocyte may drop one of six mods of the Hunter Mod Set, which consists of the following mods:
|
|
|
|
|
|
- Additionally, the Hemocyte will also drop a Hemocyte Cystolith, which is a required component for constructing a Clan trophy.
- If a player wishes to acquire all the exclusive rewards (excluding gear items) the player will need a total, from 0, 110500 (104500 from rank 3) standing. This excludes items such as Fosfor and Ether Daggers as those are found elsewhere but does include the Snipetron. Depending on the use of the mixable gear will vastly shorten the required runs. From rank 3 using 0/4 0/4 will require 104.5 runs, [0/4]/4 [4/0]/4 will require 52.25 runs, and 4/4 4/4 will require only 34.83~ runs.
Trivia
- This event was first teased as a meteor crossing the sky over the Plains of Eidolon after Update 22.2 (2017-11-01), and officially announced during Devstream 100 on November 3, 2017, with the meteoroid crashing into the Plains at 3pm EST in the middle of the Devstream.
- The event was supposed to start shortly after it crashed into the Plains, but various issues led to the event being delayed until November 15, 2017.
- The meteoroid was instantly visible in the Plains after the official announcement. Players that were on the Plains during the event could see it after leaving to Cetus and re-entering.
- This mission is tied with Lua Crossfire missions for the most opposing factions present in one mission: the Tenno, the Grineer, the Infested, and, at night time, the Sentients.
- During the last phase of the bounty, the Lotus may tell the player that the toxin has caused the boil to undergo peristalsis, which is a one-way muscular contraction/relaxation wave commonly associated with the intestinal tract.
