Councilor Vay Hek is the administrator of Earth on behalf of the Grineer Queens. He has been marked by the Lotus for assassination for upsetting the balance in the system by killing several political opponents. He is also known for being heavily modified with Grineer alterations, having little noticeable remaining flesh while he rides in his giant Terra Frame.
He can be found on the Oro node, which can be accessed only by players of Mastery Rank 5 or higher. Upon defeating him and completing the mission, players will receive a blueprint for a random component part of the Hydroid Warframe, from his Neuroptics, Chassis or Systems. Upon death, Councilor Vay Hek has a chance of dropping Neurodes and Orokin Cells.
Lore
General
Vay Hek's fanatical loyalty to the Grineer cause has driven him to spearhead numerous Grineer operations against the System. As outspoken as he is zealous, he is known for hijacking Tenno transmissions to send boastful messages, with targets ranging from Relay broadcasts to even a Devstream. Coupled with his leading position in the Grineer hierarchy and (later on) access to the formidable Fomorian fleet, he is one of the most dangerous enemies the Tenno have encountered.
The Ascension
Sometime before the awakening of the Tenno, in an attempt gain favor with the Twin Queens and prove his own worth, the up-and-coming young Councilor collaborated with Dr. Tengus to create the Grineer Ghouls - hastily-bred clones intended to be seeded from the orbit onto a targeted world, which they would proceed to conquer without the need for reinforcements or support.
In an act of betrayal, or perhaps as a deliberate stunt to showcase their ferocity to the Queens, the treacherous Tengus kicked Vay Hek into the Ghouls' enclosure, to be torn apart by the cannibalistic creatures. Impressed by the display, however, the Queens ordered Tengus to reconstruct Hek with cybernetics, turning him into the creature the Tenno eventually encounter.
Ghoul Purge
After the events of The Ascension, the ghouls' approved development has since become the catalyst of the occasional Ghoul Purge event, prompting the Tenno to occasionally sortie into the Plains of Eidolon and exterminate the ever-increasing population of the malformed creatures.
Saya's Vigil
Vay Hek is first introduced to players as the leader of the Grineer occupation of the Plains of Eidolon, and of Earth as a whole. Having learned of the legend of a powerful "Glass Warrior" who slew a gigantic Sentient in the distant past, Hek orders his forces to conduct sweeping excavations on the Plains, coming into conflict with the people of Cetus. The Tenno, searching for clues regarding the fate of Saya's missing husband Onkko, attack one of Hek's dig sites and uncover a coffer sealed with a "Shatter Lock", which could only be opened with a glass key. The Tenno race against Hek to obtain the pieces needed to reforge the key, ultimately invading Hek's personal Galleon for one. Hek attempts to stop the Tenno with a legion of Grineer, including a Nox, but the Tenno ultimately succeed in taking back the glass shards Hek had obtained.
Finally, Hek's forces, while searching for the final shard, encounter an Eidolon Teralyst. Hek briefly expresses awe at the beast's "beauty" before ordering his men to kill it. Taking advantage of the confusion, the Tenno sneaks by the Grineer and the Teralyst and obtains the Shatter Lock's final piece. Realizing this, Hek orders a final attack on the Tenno, but they successfully defeat the ambush and escape.
Operation: Plague Star
After an Infested "boil" crashes onto the Plains of Eidolon, Vay Hek attempts to exploit its presence and allow Infested lifeforms to overrun Cetus, planning to then use the Thrax Toxin to poison the boil once the Ostrons are scattered. At Konzu's request, and with the clairvoyant Quills revealing that the Infested would overrun both the Ostrons and the Grineer if left unchecked, the Tenno are tasked with destroying the boil by raiding Hek's toxin stores and applying it to the meteorite. Despite Hek's efforts to stop them, the boil is ultimately destroyed, with some Tenno utilizing various catalysts to boost the toxin's effectiveness at the expense of encountering heavier Infested resistance.
The Cicero Crisis
In terms of WARFRAME's development, this was Vay Hek's first chronological appearance. In an attempt to expand Grineer territory on Earth, Hek led a campaign to poison Earth's forests via the Cicero Toxin. He chose this extreme tactic after finding that centuries of Orokin influence had made the forest vegetation difficult to destroy by conventional means. The Tenno responded by formulating antitoxins, derived from Earth's native vegetation, and loading them into the Grineer Toxin Injector facilities to flush out the toxin.
Ultimately, Hek's attempts were thwarted and the forests were saved. But the Earth hasn't seen the last of the Cicero Toxin; a number of facilities continue to operate, although on a smaller scale.
The Grustrag Three
Vay Hek plays a prominent role in the story of the infamous Grustrag Three and their deranged, abrupt slaughter of fellow Grineer soldiers. After the Three's subsequent incarceration at the Grustrag Reconditioning Facility, Hek orders Facility Director Dr. Tengus to recondition them in the hopes that their aggression could be redirected towards the Tenno. With Tengus mostly successful (as the Three still had lingering violent behavior towards other Grineer, but not beyond a measure of control), Hek has given new orders to the Three to accompany Grineer Invasion forces and to attack anyone who stands against them.
General Sargas Ruk, another prominent figure of the Grineer military, disagrees with Hek's actions arguing that the Grustrag Three should have been executed for their crimes (with the implication that the Three and the soldiers they killed were under Ruk's command). He also warns Hek, who continues in his attempts to tame them, that the savage Three's decreasing mental stability will ultimately be his undoing.
Tethra's Doom
During Ties That Bind, Frohd Bek pleads his son Darvo to stay with the Corpus, mentioning that "Project Tethra" will ultimately be their destruction. Following this, The Lotus discovers that Project Tethra is Hek's attempt to rebuild the Fomorian fleet following their destruction during Operation Sling-Stone. The Lotus directs the Tenno to Earth to Intercept transmissions revealing the location of the Grineer Shipyards, and from there the Tenno will Hijack the Fomorian Power Cores so that they can be towed away by Liset and safely destroyed in the depths of space.
During the Tenno's operations, Vay Hek sends a transmission to the Tenno, revealing that they have been simply destroying the Auxiliary Cores and that the Fomorian Shield Cores are still intact. The Tenno simply double their efforts and hijack the Shield Cores, which are more heavily guarded in response to their initial attacks. The Tenno's actions deal a significant blow to the construction of the Fomorians, forcing Hek to go into hiding. His location is unknown to all but a hand-picked group of Guardsmen known as Prosecutors.
The Archwing
After a long period of silence, The Lotus reveals the looming threat of Hek's Balor Fomorians, and that the Tenno will have to construct an Archwing in order to combat them. Towards the end, the Tenno are sent to a Corpus Obelisk in order to uncover more information about the Fomorians, which is abruptly interrupted by the arrival of Hek and his one of the Fomorians, taking both The Lotus and Frohd Bek by surprise. As he severs the Grineer's business contracts with the Corpus, the Obelisk is ruptured by the Balor Fomorian's weapons, preventing a conventional extraction.
Acting quickly, The Lotus orders Ordis to deploy the newly constructed Archwing so that the Tenno can escape, now armed with the knowledge that Hek's forces are ready for action.
Operation Eyes of Blight
Councilor Vay Hek finally makes his move, intending to destroy the Relays with his fleet of Balor Fomorians. The Tenno are ordered to intercept the Balor Fomorians as they slowly lumber towards the relays, and damage the warships' power core in a limited window of time. Though he succeeds in destroying some of the Relays, he exhausts his fleet and ultimately fails his main objective.
Disappointed at the result, the Twin Queens send him a message voicing their frustration, particularly regarding the high costs of constructing a Fomorian. The message ends with them dismissing Hek, replacing him with Tyl Regor for planning future offensives.
The Law of Retribution
The Tenno, now out for vengeance for Hek's destruction of the relays, are guided by the Lotus to hunt down and put an end to Vay Hek. The operation leads the Tenno to the heart of the Grineer Military: first a trap on Earth, then a facility on Ceres and finally Mars. Despite heavy resistance, including The Grustrag Three and an orbiting Balor Fomorian, the Tenno manage to defeat Vay Hek though once again he escapes by flying off into the sky.
Appearance
Councilor Vay Hek has undergone extensive body modification to the point where the only visible flesh is his face, and even then his eyes and nose have been replaced with cybernetics. His mostly-intact head is attached to a yellow robotic suit (presumably containing whatever remains of his vital organs) that has the ability to fly or attach (and in the event of an emergency, detach) himself into a landbound Terra Frame for heavy combat. The suit also has a mask to protect Hek's face from incoming fire.
His Terra Frame is a massive, bipedal exoskeleton that is heavily armed and is capable of hovering over the ground for a few seconds. Despite its size, the Terra Frame is surprisingly agile, jumping to different platforms in order to reposition. It mounts a Drone launcher on its left side that ejects out Propaganda Drones and Orbital Strike Drones, while its right side is mounted with a large Hek-shaped cannon that fires rockets. The Terra Frame's design seems to have been inspired by birds, particularly its large "tail" and the screeching the Terra Frame makes during combat.
Arsenal
Councilor Vay Hek will meet the players after they walk a certain distance into the Grineer forest, laugh, and then fly away. The player(s) then have to chase him across the map and progress through multiple phases. Like General Sargas Ruk, he has armor impervious to damage except for his face and his backpack; each phase involves damaging either Vay Hek's face when his mask opens or his backpack when it glows yellow until he is forced to fly away. At low health during the 4th phase, the final phase begins and Vay Hek flies into his Terra Frame, able to be damaged without needing to aim at a weak spot, but offensively is more powerful. When the Terra Frame's health is low, Vay Hek will eject himself out and fly away, and the Terra Frame will explode, dropping the loot. Unlike other bosses, this makes him the only boss in an Assassination mission to not visibly die, which helps the idea of re-doing the boss lore-wise.

Machine Guns
Vay Hek has two mounted heavy machine guns on his back, which are surprisingly accurate even at long range. They will fire slowly and begin to spool up, similar to a Gorgon. Fortunately, the guns deal a fairly minimal amount of damage, and can easily be avoided by taking cover behind trees, boxes, etc.
Troop Summon
Randomly throughout the battle, a squadron of four Grineer units will be teleported into battle to aid Vay Hek. These units include: Lancers, Butchers, Troopers, Seekers, and Hellions. While Lancers, Butchers, and Troopers may not be much of a threat, Seekers and Hellions can prove a deadly force when the Tenno are too focused on Vay Hek.
Propaganda Broadcast
Vay Hek opens his mask and begins to broadcast to all local Grineer and Tenno in the area. Nearby Grineer will have boosted defenses and damage while nearby Tenno will have their shielding reduced to half. As Vay Hek's mask is open, this is the only chance Tenno have to damage him and silence his broadcast. Grineer and Tenno who are affected will have an orange aura around them.
Disruptor Shock
From the second phase on, Vay Hek can target a single nearby Tenno and shock him with a burst of red electricity from his hands. An effect similar to being hit by a Ancient Disruptor will distort the screen while energy and shielding will be drained. The bolt moves very quickly, and can be very difficult to avoid without fast moving tactics.
Disruption Wave
Vay Hek will begin using this on the third phase. Unlike Disruptor Shock, which targets a single Tenno, Vay Hek will release a fast moving wave of red electricity that travels across the floor. Any Tenno caught in the wave will be drained of shielding and energy and have their HUDs distorted. Like the Disruptor Shock, it can be hard to avoid the wave without careful planning.
Health Drain
When below maximum health, Vay Hek will float near a Grineer unit and begin to sap him of his health. If the Grineer is killed by Vay Hek, he will restore a portion of his health. This can be avoided by dispatching the affected Grineer before Vay Hek can.

Hek Cannon
Vay Hek launches a tracking missile that can deal a significant amount of 
Blast damage, and can cause knockdowns frequently. Unprepared Tenno can be easily defeated, as the explosions have a wide radius and track moving Tenno. Unlike the Bombard missiles, which follow a Tenno directly, Hek's missiles will predict where a Tenno is running towards, making it difficult to avoid.
Hek Barrage
When low on health, Vay Hek will instead launch 4-5 missiles simultaneously, which is almost guaranteed to cause heavy damage to any Tenno with the radius of the explosions.
Drone Launch
Randomly, Vay Hek will launch 1-4 Drones from his left arm cannon. The number of Drones is dependent on how many Tenno are currently fighting Vay Hek. Drones will float around the area, mostly following the Tenno or staying near Grineer troops. The Drones have two variants, a blue Propaganda Drone or a more deadly red Orbital Strike Drone. Both drones have a small amount of health and can easily be destroyed, dropping ammo, health orbs, or energy orbs.
Propaganda Drone
A blue drone a floats around empowering nearby Grineer units while reducing nearby Tenno's shields. They do not deal any kind of damage, but can still boost the power of the Grineer backup and Vay Hek himself.
A dangerous red drone that chases after the Tenno. When a Drone is close enough, it will lock-on to the last location of a Tenno and begin to call in an orbital strike. If the Drone is not destroyed before the lock-on is finished, the orbital strike will fire, creating a massive explosion that deals massive damage to any Tenno within the radius.
Shockwave
If any Tenno wanders too close to Vay Hek, he will jump up and slam the ground, causing a slow, but wide shockwave similar to a Shockwave MOA. While the damage is negligible, a knockdown can leave a Tenno open for Grineer fire or Vay Hek's Charge.
Charge
Used when a Tenno is a medium distance away, Vay Hek will charge up and ram the Tenno, dealing a bit of damage and knocking them back a fair distance, usually into the pit at the center of the area.Strategy
Vay Hek's protection consists mainly of Ferrite Armor, meaning that weapons with high Script error: The function "Proc" does not exist. and/or Script error: The function "Proc" does not exist. are extra effective. However, Vay Hek and his Terra Frame possess a large amount of health that has no resistances or vulnerabilities against any damage type, making him a difficult damage sponge. Thus, it's recommended to use your best weapon with overall high damage to defeat him (For example, an excellently modded Paris Prime will crit him frequently, so the fight will be relatively easy). This also makes Vay Hek difficult to defeat solo, and it's preferable to run this mission with a well-equipped squad.
While fighting his Drone form the vulnerable spot on his back is much larger and moves around far less than his face, making it an easier target. It will become vulnerable, indicated by glowing yellow concentric circles, for a short time after Vay Hek uses his Disruptor Shock attack.
It appears that Vay Hek has issues when all players are above him while in Drone form, and at times he will stop moving much at all, generally just swaying in place. You can use this to your advantage if you are finding his mobility is severely impacting your ability to land shots.
Alternatively, if you are having troubles hitting weak-spots reliably, Script error: The function "Proc" does not exist., Script error: The function "Proc" does not exist., Script error: The function "Proc" does not exist. and Script error: The function "Proc" does not exist. procs are able to bypass this requirement. Their Damage over time effects will steadily harm Vay Hek once his weak-spot is exposed.
It is of critical importance to kill the reinforcements (Lancers, Troopers, etc.) on the floor in the last boss area. Doing so will prevent Vay Hek from regenerating his health and will make the fight much easier.
It is also advised to bring Team Ammo Restores if the fight is going to be long because Vay Hek in Terra Frame form has quite a lot of health and players with automatic weapons will run out of ammo fairly quickly. High-powered, single shot weaponry like heavy pistols and sniper rifles, however, are not as likely to need ammo, provided most of the shots hit their mark.
If getting a group is not available, it is still possible to solo Vay Hek, albeit much harder. One will need a weapon that either has a high corrosive stat and/or puncture stat, as those are the weapons capable of doing the most damage to him.
Weapons that rely on sustained fire for damage like the Soma or Braton are not recommended as these weapons typically run out of ammunition too quickly against Hek in a straight-up fight unless one is confident they will have enough ammo to sustain themselves. Instead, high-powered, single shot weaponry like the Paris, Lex, and Latron are recommended, as these weapons typically have more than enough ammo to drop Vay Hek during all of his encounters and they are much more ammo-efficient when it comes to scavenged ammo.
A heavy Warframe like Rhino is advisable, but equally agile Warframes like Mirage can be viable as well. From there, one simply needs to play a game of cover-based hit-and-run with Hek. Shoot him from cover when he closes in on you, re-position to another area, and repeat the process until his health has been withered down.
Utilizing Warframe Abilities
Warframe abilities that give status effect immunity, such as Hydroid's Augmented Tidal Surge, Oberon's Hallowed Ground, Nezha's Warding Halo (and similarly, Safeguard), Rhino's Iron Skin and Trinity's Link allow squad members to ignore Vay Hek's Disruptor Shock, which is considered as a Magnetic status effect.
Mobile frames such as Ash, Loki, and Zephyr make it easier to re-position yourself in front of Vay Hek's face in case he turns away from you.
If timed correctly, Frost's Avalanche can be used to freeze him while his mask is open, allowing for a large amount of damage to be dealt. Avalanche is also useful in the Final Phase as it can freeze the Terra Frame in place, protecting the player from damage and allowing the player to attack him without much trouble.
Rhino's Rhino Stomp is capable of stopping Vay Hek in both forms, and if timed well can be used to enable short periods of heavy damage dealing. In particular, this can be used to make dealing with the Drone form significantly easier.
Mag's Magnetize can make damaging Vay Hek while he is drone form much easier. He can still only be hurt while showing his weak points, but applying Magnetize makes targetting much more forgiving. It should be noted that due to Vay Hek applying the magnetic status to players in close range (and thus sapping their energy), care must be taken to try and stay as far away as feasible.
Ash's Blade Storm will hit him with moderate Damage before and during the Final Phase
Loki's invisibility renders the fight a trivial matter as it provides an absolute offensive advantage with near zero risks. Should one bring heavy hitting arsenals to the fight, Vay Hek can be taken on solo and defeated in a manner of minutes.
Utilizing Titania's Razorwing will cause Vay Hek to ignore the Tenno and focus on the drones. However, Vay Hek will attempt to follow the drones, and as the drones tend to circle around the target, it may be difficult to target his face.
Using The Environment
The final boss arena in which Vay Hek appears is a large open area with a deep lagoon in the middle. A short tunnel directly in front of the area's entry point can provide cover against Vay Hek's attacks in an emergency, and act as a safe area to regenerate shields. This tunnel may be closed off until an explosive barrel behind a grate uphill is destroyed.
Several objects in the arena, from large fans to high-pressure steam vents - can be interacted with to create powerful wind flows that can propel a Warframe up and forward, allowing a Tenno to traverse the entire arena quickly. This can be useful when catching up to Vay Hek's highly mobile Terra Frame that tends to hop quickly from place to place, and they can also serve to get Warframes away from explosive AoE attacks.
The lagoon in the middle of the arena can pose a significant impediment to Warframe mobility when trying to escape Vay Hek's AoE attacks. To mitigate this, there is a tram hanging from the top of the arena with explosive barrels attached to it.The barrels can be destroyed to drop the tram into the lagoon, creating a bridge that allows for better movement in between each side of the lagoon.
Notes
- In Update 13.0 (2014-04-09) Vay Hek was removed from the Star Chart on Earth and his new version became only accessible by using a key called "Vay Hek Frequency Triangulator".
- In Update 15.13 (2015-02-05) Vay Hek was returned to the Star Chart on Earth and can be accessed without a key.
- Vay Hek's flying form can be scanned 4 times each mission, one for every instance of his appearance when he fights.
Trivia
- If the Grustrag Three are fully scanned, it is revealed that each of them was worked upon by a "Doctor Tengus" who was authorized by Hek himself. Little is known about him, but it is made very clear that he is a prodigy in the field of cybernetics, indicating that he may have had something to do with Hek's mechanical rebirth.
- Councilor Vay Hek was the person responsible for both The Cicero Crisis and Project Tethra.
- Councilor Vay Hek was the fifth boss & fourth Grineer boss in the game to receive a complete rework, following Lieutenant Lech Kril, Captain Vor, & General Sargas Ruk.
- Vay Hek was originally targeted for assassination by Lotus as he is a corrupt diplomat who has assassinated multiple political opponents and is a hindrance to the stability of the system.
- The new Hek appears to have run from the Tenno in a paranoid panic, leaving him vulnerable if he could be tracked down. This becomes the new reason for Hek to be targeted after Update 13.
- Prior to his rework in Update 13.0 (2014-04-09), Vay Hek was a grey colored Lancer with increased stats who wielded a Hek and was capable of creating three copies of himself that did no damage when he reached a certain health percentage. Before Update 13, when he started dropping Hydroid he dropped the components to Oberon. Before Oberon was released, he dropped Trinity components.
- Because of this, he has dropped parts for more individual Warframes than any other boss.
- Vay Hek's pre-rework quotes had some grammar issues.
- He can be seen, in his new form, in audio messages during The Cicero Crisis. His appearance suggests he underwent vast body modifications similar to General Sargas Ruk or acquired a battle suit of similar nature.
- The reworked Councilor Vay Hek seems to be more capable of speaking English than any other Grineer so far. He even has recorded voice clips on all Frontier Regulators spoken in full English when empowering the Grineer units.
- Councilor Vay Hek and Tyl Regor are, by far, the only two characters in Warframe who are found the most agitated by the presence of the Lotus, saying that they would personally kill the Lotus once the Tenno have been exterminated from the Solar system, unlike Captain Vor, Lieutenant Lech Kril and General Sargas Ruk who simply disregard the Lotus and instead see the Tenno as the actual threat.
- Despite the fact that Councilor Vay Hek is known for political assassinations among public alliances, his pre-rework quotes generate a certain air related to leisure entertainment. These include as gambling, joke-cracking and aggressive commandments, which makes Vay Hek surprisingly similar to many fictional dictators with decent relationships among his peers.
- Hek has been the source of more Warframe components than any other individual boss, having dropped Trinity, Oberon, and currently Hydroid component blueprints.
- Hek is the only boss that is unaffected by the Nukor's visual growth.
Bugs
- Getting defeated by him may render you to become unable to move, shoot or use skills. You may even be pulled from your warframe in a sort of out of body experience. You will be able to see your warframe as if it were another players warframe. Energy may be left at "1" and it will say you are unarmed. Checking mission progress will show NO rewards or experience, it will all be blank. Letting your warframe die MAY fix this, not guaranteed. Other than having someone else complete the mission, there is no sure fix. You may or may not get rewards/experience after the mission ends.
- After defeating him, the water in the tunnel may not stop, making it impossible to leave the arena for extraction without the use of abilities such as Excalibur's Slash Dash, Rhino's Charge, Hydroid's Tidal Surge, Volt's Speed, Zephyr's Tail Wind, Valkyr's Rip Line or the Bullet-Jump maneuver.
- After defeating him, he flies off, leaving a zero health Terra Frame that continues to attack and is impossible to destroy.
- Skipping the beginning cut-scene can sometimes cause Vay Hek's laughter to still be played in-game.
- Sometimes he won't retract his mask.
- In the final area, if you fall into the pit, you may end up getting stuck in an endless falling loop.
- The current of water in the tunnel that leads to his arena can be completely resisted by Rhino's Iron Skin, allowing you to stay in it freely.
- During the final battle, he may occasionally fly into the pipe that served as your entrance. It is possible for him to get stuck back on the other side of this pipe, in which case you will have to fight your way upstream. Once his first form is defeated on this side he will respawn in his second form back in the proper place.
- When farming him for color pigments, he only drops them rarely - regardless of all methods mentioned in other forum posts. i.e.: not skipping the cut screens, not killing him fast or let him finish his speak-lines first, shooting at least one of his drones, letting him heal himself at least once. he is the only boss enemy with color pigments that not dropping a pigment after defeat.
- Sometimes he escapes soon after entering the Terra-Frame and with more than half of his hit points left - resulting still in victory but not dropping anything.
- Vay Hek, while in Drone Form, will occasionally shout "We are not done here, Tenno!" and leave the battle prematurely during the final encounter. This will set the objective marker above the platform where his Terra-Frame is supposed to spawn, but nothing will occur, causing the mission to soft-lock. The players' Warframes are also blocked from exiting back out the entry pipe by an invisible wall.
Media
Patch History
Update 22.10 (2018-01-25)
- You can now damage Vay Hek up to 25% of his total Health (was 10% previously) while his Propaganda Drone is active before it shuts off. This will result in less waiting around, and will make Vay Hek in Terra Frame easier to deal with.
- Reduced base Armor of Vay Hek in his Terra Frame from 225 to 200.
