“It is done. Operation: Orphix Venom is no more.”
This event has concluded on all platforms.



Stop the Sentients!

Father is putting his Necramechs to the challenge in Operation: Orphix Venom! The Sentients have resumed their campaign against the Origin System and have deployed weaponized pulses cleverly designed to disable Warframes! Arm your Necramech to take on the Sentient Orphix, or Transference into a fallen Necramech found in the Operation.

Operation: Orphix Venom is the second Sentient invasion against the Origin System as part of The New War story arc. This event pits the Tenno's Necramechs against Sentient enemies with Grineer and Corpus caught in the crossfire in normal tilesets.

The event lasted from December 18, 2020 2:50 PM ET to January 18, 2021 2:00 PM ET on PC and from January 21, 2021 3:20 PM ET to February 21, 2021 3:20 PM ET on all consoles.

Event Synopsis[]

Following the Tenno's victory and the Sentients' defeat in Operation: Scarlet Spear, Erra and the Sentients have retreated and gone into hiding. The second Sentient invasion in the Origin System thus begins, and the Orphix Sentient Units return, but this time they have been taught to override Warframes by deploying weaponized pulses cleverly designed to disable them, leaving the Necramechs as the Tenno's last option.

During the Operation, Natah transmits messages to the Tenno, revealing that she was the one who taught the Orphix to disable Warframes. Her messages about deploying the Orphix series, containing a letter followed by a number, reveal a code from ordering the numbers, which says: "I AM DYING".

How to Start[]

To participate in the event, players must have completed The War Within and Heart of Deimos quests to gain access to Operator mode and to perform Transference into fallen Necramechs.

Phasic Cells Phasic Cells are a unique event-exclusive currency that can be gained by completing Orphix Venom missions. They are earned at the rate of 1 Phasic Cells per 10 points. For every second that there are no active Orphix on the map, players will earn 1 points. Additional points can be earned for each Sentient killed and a base 100/150/200 points are rewarded for destroying Orphix on Normal/Advanced/Endurance missions. Score gain per destroyed Orphix will scale in all difficulties based on the following formula:

Score per Orphix =

where N is the number of reward rotations, up to 8 for Normal/Advanced missions and 12 for Endurance.

Total Score per Rotation=

Phasic Cells gained in a mission = rounded down

Each Orphix has an initial value of 100 points in the first Operation mission. As your fight evolves, so will the Orphix, awarding you more points at a greater difficulty. Orphix will be worth 200 points at the hardest difficulty (Endurance), and scale up from there! Kill Sentients to increase your score as well. The higher your score, the more Phasic Cells you'll walk away with.

Try to survive for as long as possible - The first two Operation missions have a limit of 24 Orphix spawns. 36 Orphix will be the maximum amount in the Endurance mission. Orphix kill points go up with high level mission types. Endurance missions with a 36 Orphix spawn grant the highest possible score.

Phasic Cells can be earned in any Operation mission. However, Endurance gives the most points per Orphix. While this Operation is possible Solo, better results will come from coordinated Squads.

The event missions are modified Survival missions that require players to defeat Orphixes in a timely manner in order to survive.

Orphix Spawns[]

Orphix spawns are not random and occur once every 1 minute and 30 seconds, cycling through three distinct tile locations. The following diagram shows how the Orphix spawn locations are laid out in a linear fashion.

A 🡆 B 🡆(C)


(C)🡆 B 🡆 A
 🡅       🡇
 C 🡄 B 🡄 A


(C)🡆 A 🡆 B
 🡅       🡇
 C 🡄 A 🡄 B

Example Orhpix spawns

The Orphix spawn pattern starts with Tile A, Tile B and then Tile C. After the 3rd Orphix, it changes to use the spawn pattern CBA-ABC or CAB-BAC. Note that spawning tiles will be adjacent but not necessarily in linear arrangement and probably have branch paths that lead to dead ends.

Fighting the Orphix[]

Orphix radiate a pulse field that disables Warframes and dispels any buffs and active abilities. Crossing into the pulse field with the Warframe will force the player into Operator mode to rely on their Necramechs via Necramech Summon. If the player does not own a Necramech, there will be fallen Necramechs to use Transference into, which are rank 30 and equipped with a Mausolon.png Mausolon but are unmodded.

There are two distinct phases when fighting an Orphix: destroying Orphix Resonators and weakening the Orphix.

The Orphix is protected by three or more Orphix Resonators near it and can only be damaged when all Resonators are destroyed, opening up its center blue cavity to spawn more Sentient troops to help defend it. In ascending order of frequency, Orphix can spawn Aerolysts, Summulysts, Choralysts, Ortholysts, Symbilysts, Conculysts, Battalysts, and Brachiolysts. At 50% health, the Orphix will close up its cavity to respawn Resonators. Once the Orphix is dead, all Sentient enemies spawned by that Orphix will disappear. The Sentient control meter will also decrease by 50% upon defeating an Orphix.

After successfully destroying three Orphix, players may extract or continue destroying more Orphix, up to a maximum of 24 in normal/advanced missions and 36 in the endurance mission. Orphix will continue to spawn even if one is active; if Orphix are left active for 100 seconds (100% Sentient control), players cannot continue and are forced to extract. A mission failure will result if Sentient control reaches 100% when the player has not destroyed three Orphix.

Orphix Damage Resistance[]

Main article: Orphix#Damage Resistance

Orphix possess DR that scales depending on your weapon's DPS excluding Critical Hits. DPS is calculated by:

Critical Hits are applied after DR is calculated. Additionally, the average DPS is calculated using Health Modifiers and is quantized.


  • The Necramech Summon has a 1 minute cooldown to revive the Necramech instead of the usual 3 minutes.
  • Players must hit the glowing blue cavity of Orphix with a direct hit to deal damage with area of effect weapons. Radial damage alone will not damage Orphix and is only applied to direct hit attacks.
  • Resource Boosters and Smeeta Kavat's Mod TT 20px.png Charm does not affect the number of Phasic Cells rewarded from event missions as they are directly rewarded based on point score rather than as a drop.
  • Orphix Resonators have 3,000 Object health.
  • The event missions count towards challenges that involve survival missions, such as weekly Nightwave Acts.
  • Tenno Specters will be killed instantly if affected by the Orphix pulse field.
  • The Granum Void and captured Solaris are unavailable in the Corpus Ship tileset.


  • Early in the mission Orphix Resonators can be instantly destroyed with the Operator's Void Blast or Necramech's Melee, Slide, and Slam Attack.
  • While there are free Necramechs for use, their unmodded state means they won't get very far with the higher leveled enemies.
  • ArchRocketCrossbow.png Fluctus and SundialRifle.png Zenith have infinite punch through and can damage the Orphix Resonators from everywhere.
  • Mausolon.png Mausolon's alt fire and ArquebexFixed.png Arquebex deal massive damage to all enemies and the Orphix.
  • Ironbride.png Ironbride is capable of damaging the Orphix from any angle.
  • Warframes can still use their abilities outside the pulse field. The following Warframes can continuously generate energy orbs for Necramechs:
  • If a Warframe is equipped with Mod TT 20px.png Combat Discipline, kills that the user gets with the Necramech will not drain health from the inactive warframe and will instead heal their own Necramech. This will also heal other players' Necramechs and Warframes as usual.
    • With the number of enemies that spawn, using this with a weapon that can kill large groups of enemies at once can easily keep the entire squad alive.
  • Use Voidrig's Storm Shroud and Bonewidow's Meathook and Shield Maiden to stay alive.
  • Building for DmgCorrosiveSmall64.png Corrosive will allow for maximum damage against the armored Orphix and Sentients, who all use Ferrite Armor.
  • The Battalyst's omni-directional laser makes it arguably the deadliest enemy, dealing a lot of damage very quickly multiple Necramechs at long range. The Bonewidow's Meathook can instantly interrupt its attack and render it out of commission.
  • Using a Warframe with Dispensary130xDark.png Dispensary is a good way to always have energy for the Necramech.


  • The destruction of your Necramech can lead to a loss of previously collected EXP in the mission for both the equipped Archgun and the Necramech.

Patch History[]

Hotfix 29.6.7 (2021-01-13)

  • Fixed Operation exploit (and disqualified scores that had been earned with it.)

Hotfix 29.6.6 (2021-01-12)

  • Fixed another Operation exploit related to slow connection Hosts.
  • Fixed losing Affinity for Necramech weapons if a Host migration occurred while piloting a Necramech with their ultimate Ability active. This also fixes a script error occurring when Reviving after the Host migration.

Hotfix 29.6.5 (2021-01-09)

  • Removed Solaris prisoners in the Operation tileset as no Granum related activities are meant to be present in the respective tileset.
  • Fixed another Host migration related scoring exploit.
  • Fixed an End of Mission crash when an Orphix attempts to spawn.
  • Fixed rare cases where Resonators would spawn behind locked puzzle doors in the tileset.
    • It is unlikely that this should come up again, but if it does, it is essential that you take a screenshot with the in-game tool using the F6 key and send the unedited file to Support; screenshots taken this way have special embedded data that will help us find out why the game chose to place the Resonator where it shouldn’t be. Thanks!
  • Fixed having Voidrigs Storm Shroud run out on your personal Necramech while you’re in a rent-a-Mech resulting in your personal Necramech becoming invincible.
  • Fixed Extraction countdown being reset by enemies/Pets entering the Extraction zone (also occurs in normal Survival missions).

Hotfix 29.6.4 (2021-01-06)

  • Over the course of the Holiday break, the team continued to track and fix Operation exploits. Any scores that were determined to be achieved with these exploits have been (and will continue to be) removed from the Leaderboards, and temporary or full suspensions have been issued where appropriate.
  • Fixed proper AABC reward not being given when achieving the Endurance max 36th Orphix.
  • Fixed an issue where Affinity collected in a Necramech wouldn't propagate to your Arch Gun if you Transferenced in from the Operator.
  • Fixed second Necramech death resulting in a functionality loss as the Operator until Operator respawns.
  • Fixed having the same Archwing Weapon equipped in the Heavy Weapon slot and the Necramech Primary slot resulting in receiving double Affinity for the weapon.
  • Fixed an issue where the player's inventory can end up with two instances of the Necramech's gun, which resulted in losing earned Affinity when Reviving as your Warframe.
  • Fixed missing Extraction UI if a Host migration occurs after killing the 36th Orphix.
  • Fixed Focus gained by the Necramech not being saved at End of Mission.

Hotfix 29.6.3 (2020-12-22)

  • Fixed players being prevented from summoning Necramechs if they are too far away (applies to the Operation and Landscapes).
  • Fixed an issue where Leaderboard scores were not appearing if you had a higher score before they were added. Your score shown on Profile from before the Leaderboard went live will not appear on the Leaderboard. This change just means that you can now set a Leaderboard score if it’s lower than what your Profile shows.

Hotfix 29.6.2 (2020-12-22)
With this Hotfix comes the enabling of Operation: Orphix Venom Leaderboards and Clan Trophies!

Operation: Orphix Venom Changes & Fixes:
  • Reduced the bright screen range from the Orphix death to 25 meter range (from 120 meter).
  • We now show your current amount of Phasic Cells in Father’s Operation shop in the Necralisk
  • Operation Orphix will now sort higher on Navigation’s list of current events than fissures or ghouls
  • Optimized the behaviour that when casting Voidrig’s Guard Mode with exactly 50 energy, you just jam your guns and go through the animations without actually being able to use the ability. You can no longer cast when you’re at exactly 50 energy.
  • Changed the height threshold for Necramechs to do the ‘hard landing’ behaviour to be much higher. This change was made because often you’d just hop on a flat floor and be stuck in the ‘hard landing’ behaviour animations which would disrupt flow.
  • Fixed a case where you’d be unable to use Abilities in your Necramech if you resummoned it and its last position was inside an Nullifier.
  • Fixed some erroneous ‘Up/Down’ actions visible for players in a Necramech.
  • Fixed being able to damage an Orphix before it spawned (i.e slashing empty air).

Hotfix 29.6.1 (2020-12-18)

  • Fixed several crashes related to Operation: Orphix Venom.
  • Fixed two players being able to occupy the same Necramech in Operation: Orphix Venom.
  • Fixed a crash associated with Equinox abilities on Orphix Venom.
  • Fixed an issue where Orphix would not be destroyed even if their health was at 0.

Update 29.6 (2020-12-18)

  • Introduced.
