Vay Hek is a Grineer boss that you encounter in Oro (Assassination Mission), who was marked for assassination due to the dangers his actions lead to.
Through his violent acts of killing his enemies on the Grineer council, he has gained a lot of power that has allowed him to remain in control.
Due to his plans to achieve complete system domination, he has now been marked for death with a contract, which is where you come in.
Vay Hek Location
You will encounter Councilor Vay Hek in the Oro Assassination Mission on Earth, which is unlocked after you have completed the Erpo (Archwing) mission.
The Tenno will be deployed on Earth, where they will need to pursue Councilor Vay Hek and attempt to assassinate him.
How to Defeat Vay Hek?
Phase 1
At the beginning of the mission, you will immediately encounter Vay Hek as you are making your way to the waypoint, which is when he gives a quick intro before fleeing.
You will need to continue pursuing him into 3 different areas and each time you encounter him, you will need to damage and continue the chase when he flies away.
Damaging Vay Hek can be done by shooting the glowing weak spots, which are either his face or the augmented part on his back that become vulnerable after a period of time.
Phase 2
After dealing a certain amount of damage to Vay Hek and pursuing him (3 times), you will eventually reach the final area by making your way through a damaged pipe.
This is where Vay Hek and his Grineer minions will begin to attack you, resulting in you having to fight back and deal enough damage to Vay Hek by targeting his vulnerable spots.
Once enough damage has been dealt, Vay Hek will call down a Terra Frame (Large Mech) that he enters, and the fight will continue.
Phase 3
The Terra Frame will be vulnerable to all kinds of damage, allowing you to attack him freely but he does become stronger with the robotic body.
You will need to damage Vay Hek with your weapons and/or abilities until you reduce his health to the point where it is empty, destroying the Terra Frame in the process.
Instead of dying though, Vay Hek will eject from the Terra Frame and will flee from the area while you will then be prompted to make your way to the extraction point.
Councilor Vay Hek Weaknesses
Councilor Vay Hek will be almost invulnerable in his drone form except for his weak spots but when his Terra Frame is equipped, you can damage him on any part of his body.
The following are the stats and weaknesses for each form:
1) Vay Hek Drone Form
Vay Hek will attack you with his machine guns even at long range or will shock you when he gets close to you, which can inflict the Magnetic Status Effect.
He may also unleash a wave-like shock attack that travels along the floor and will occasionally drain his Grineer allies of their health to restore his own.
Ferrite Armor (225)
- Corrosive+++
- Puncture++
Machinery (1800)
- Blast+++
- Electricity++
- Impact+
2) Vay Hek Terra Frame Form
While in his Terra Frame, Vay Hek features different attacks such as leaping into the air to slam the ground to create a shockwave that may knock you down.
He will also attempt to charge into you from medium range or may use his cannons that will track and explode on impact. (He launches multiple projectiles when his health is low)
Aside from fighting with his Terra Frame, he will summon drones (the amount is determined by how many are in the squad) that have two variants.
Blue drones will empower Grineer units while red drones will call down orbital strikes once they get near you or your allies.

Tips
- Bringing an accurate weapon can make it easy to shoot Vay Hek in his weak spots, but you can also use other weapons and attack him up close. (Be careful of his shock attacks)
- Certain abilities and status effects may affect the Terra Frame, but these will often be reduced and are still useful.
- Once Vay Hek enters his Terra Frame, you can either attack him from afar or close in on him based on what weapons you are using.
- The Grineer in the area will continue to fire at you but moving around can delay their attacks as they will attempt to approach you.
Verdict
Vay Hek can only be defeated in the final area and while you are in pursuit, all you need to do is damage him a bit before you can move on.
His armor and health for his Drone Form and Terra Frame are the same with little difference in their values, which makes it easy to build your weapons to do extra damage.
Even though you manage to pursue Vay Hek and deal a lot of damage to him, he will eventually escape in the end before he is killed.
