OPERATION: PLAGUE STAR RETURNS

WEDNESDAY, SEPTEMBER 10TH @ 11 A.M. ET – WEDNESDAY, SEPTEMBER 24 @ 11 A.M. ET.

Tenno!

Ostron scouts have returned with foreboding news: the Plague Star has struck the Plains of Eidolon once more. Vay Hek possesses a toxin that can destroy the boil at the meteorite crash site, but he refuses to help; steal his toxin and destroy the boil before the Infested make their way to Cetus.

And yes, your Operational Supply Standing/Rank is still intact from the last time you played Operation: Plague Star!

Event Changes and Fixes
Operation Plague Star has received a few changes and fixes — since these were not relevant to the hotfixes they shipped in, we’re outlining them below as quasi-patch notes:

• Reduced the Damage Attenuation on the Hemocyte to make it less oppressive.
  • We will be talking more about our wider plans for Damage Attenuation in our next Devstream!
• Fixed Hemocytes not having the “VIP” status of other bosses.
• Fixed endless enemies spawning in the final Bounty phase while all players are currently down.
• Fixed enemies being paused following a Host Migration during the Mixer Defense Bounty phase.

Additionally, Operation: Plague Star is receiving a few new items to its event store, including a one-time purchasable Omni Forma! For more details, please refer to the event rewards section.

What you’ll need to know
Operation: Plague Star features three bounties: Plague Star, Plague Star – Advanced, and Plague Star (The Steel Path). As expected, each increase in difficulty will reward more Operational Supply Standing per Bounty.

The Advanced and Steel Path variants will require an Eidolon Phylaxis and an Infested Catalyst. You can pick up the Eidolon Phylaxis Blueprint from Nakak in Cetus for 2,000 Standing, and the Infested Catalyst Blueprint from your Dojo’s Bio Lab Research Room.

Visit Nakak in Cetus to increase your rank in the Operational Supply Syndicate, or exchange your Operational Supply Standing for event rewards!

What you’ll need to do
Konzu has a Plague Star Bounty with your name on it. Select your chosen difficulty and complete a series of Bounty Missions to earn Operational Supply Standing!

UPDATE 9/10/2025: Aligning with our 2023 re-run of Operation: Plague Star, Operational Supply Standing Bounty Reward amounts have been live-patched to reflect those values, as follows:

Plague Star - Standard
Stage 1 - 50
Stage 2 - 300
Stage 3 - 100
Stage 4 - 575
Total Operational Supply Standing: 1,025 (was 1,000)

Plague Star - Advanced
Stage 1 - 200
Stage 2 - 1000
Stage 3 - 300
Stage 4 - 1700
Total Operational Supply Standing: 3,200 (was 3,050)

Plague Star - Steel Path
Stage 1 - 200
Stage 2 - 1100
Stage 3 - 400
Stage 4 - 2100
Total Operational Supply Standing: 3,800 (was 3,650)

Bonus Operational Supply Standing:
Standard: 25
Advanced: 75
Steel Path: 100

Bonus Operational Supply Standing is lower, but overall, players receive slightly more overall Standing than before!
