CODEX

Protected by impenetrable armor.

The Juggernaut is a large, quadrupedal Infested creature armed with formidable ranged attacks and deadly close-quarters combat abilities. Combining these threats with its heavy armor shell, the Juggernaut becomes an intimidating opponent. The Juggernaut's abilities include a charging body attack, a ranged spine strike (a scaled version of the Phorid's similar attack) and the ability to resurrect a number of nearby dead Infested.

Tactics

The Juggernaut will make its presence known on any non-Endless Infested mission by roaring accompanied with flickering lights, in a fashion similar to assassins like the Stalker. The roar will buff a number of Infested units within the vicinity of the player, indicated by an orange aura around them. The Juggernaut will only spawn if several of these buffed units are killed. The more players there are in a Squad, the more Infested must be killed to lure the Juggernaut out. When enough kills have been reached, the player will hear another roar along with a Transmission from the Lotus. If the player does not wish for the Juggernaut to spawn, they may simply avoid combat until it moves on. Note that the killing challenge to spawn the Juggernaut will not trigger if the player is too close to enemies.
- The Juggernaut's Roar will also disable active powers like Mind Control to all Infested within range.
Similar to Lephantis, the Juggernaut has a mechanic which limits the amount of damage players can do per shot. Players can reliably deal more damage to the monster by attacking its two weak points:
- The first weak point is the glowing stomach located on its underside, which the Juggernaut will expose before performing its ground stomp attack. Even when unexposed, it is possible to bounce launcher explosives underneath of the creature and damage the weak spot that way.
- The second weak point is the maw on its back from which the Juggernaut launches its ranged attacks. The maw stays protected for all but a split second when it is opened. Successfully attacking this spot causes massive damage, but beware its lethal spine strike which can decimate lightly armored Warframes with a single barrage.
The Juggernaut is incapable of climbing high surfaces. If it cannot be defeated, simply luring the Juggernaut into a deep pit can render it mostly harmless.
The Juggernaut can be damaged by Trinity's Energy Vampire. Percentage based damage such as Slash completely bypasses the Juggernaut's armor.

Farming Locations

These are based on opinions and may not be 100% true. These should be viewed as advice for finding the enemies until better facts are proven.

Planet	Name	Type	Level	Tile Set
Eris	Saxis	Exterminate	34 - 38	Infested Ship
Eris	Isos	Capture	32 - 36	Infested Ship
Europa	Armaros	Exterminate	18 - 20	Infested Ship
Deimos	Horend	Capture	12 - 14	Orokin Derelict
Deimos	Cambion Drift	Open World	20 - 35	Cambion Drift
Eris	Jordas Golem Assassinate	Assassination	32 - 34	Infested Ship
Deimos	Magnacidium	Assassination	20 - 25	Orokin Derelict

Juggernaut spawns reliably on Isos, Eris; Armaros, Europa and Magnacidium, Deimos. Ignore the Infested along the way, capture your target, and the Juggernaut will roar shortly after. For the Sands of Inaros quest step repeat this five times.
When running the weekly Survival mission with Clem, a Juggernaut will spawn and attack the Tenno at the five-minute mark so long as the tileset is controlled by the Infested.
The Juggernaut will spawn only when a large portion of the buffed infested are killed within about a minute of its original roar.
Players need not kill any Infested to trigger the Juggernaut's roar. For parties who wish to provoke the Juggernaut, a common tactic is to run past all infested until the first roar and then turn and kill them all.
Juggernauts in the Cambion Drift primarily spawn while undertaking bounties during the Vome cycle.

Damage Resistance

A DPS cap is applied when hitting a Juggernaut's armored plating. While hitting this, the Juggernaut cannot take more than 500 damage per second.

Slash procs from Hunter Munitions will bypass this DPS cap, but will have the DR in the following section applied.

A Juggernaut's weak points (the belly and back when exposed) possess DR that scales depending on your weapon's DPS, including critical hits when triggered, where DPS is calculated by

(\text{total damage})\cdot(\text{total fire rate})\cdot(\text{critical multiplier if triggered})\cdot(\text{total multishot})\cdot(\text{body part multipiers})

Weak points also take 2x more critical damage. Additionally, the average DPS is calculated using all health/shield/armor modifiers, including damage reduction from armor and is quantized. Damage from procs uses the same calculation where proc damage replaces total damage.

${\displaystyle { \text{Damage Modifier} = \begin{cases} 1,\; & \text{DPS}_{Average} \leq 1000 \\ 0.5 + \frac{500}{\text{DPS}_{Average}},\; & 1000 < \text{DPS}_{Average} \leq 4000 \\ 0.2 + \frac{1700}{\text{DPS}_{Average}},\; & 4000 < \text{DPS}_{Average} \leq 10000 \\ 0.1 + \frac{2700}{\text{DPS}_{Average}},\; & 10000 < \text{DPS}_{Average} \end{cases} }}$

Notes

Can be chained with Harrow's Condemn.
Can be affected by Banshee's Sonar to deal additional damage, making it much easier to deal much more damage while its maw is closed.
Can be put to sleep by Ivara's sleep arrows, although for minimal duration.
Can be resurrected and enthralled by Nekros' Shadows of the Dead.
Can become mind controlled by Nyx, although for minimal duration.
Ash's Seeking Shuriken augment and a Kavat's Sharpened Claws will both strip a Juggernaut's armor.
Nidus's Virulence seems to bypass the Juggernaut's armor.
- The Phage will also somewhat bypass it, dealing minor damage over time.
- Orvius's channeling thrown attacks will also ignore Juggernaut's armor.
Mirage's Hall of Mirrors copies can be used to lock Juggernaut into a ranged attack cycle with some positioning, which allows for free shots in vulnerable parts.
Octavia's Mallet can be used to easily and passively kill the Juggernaut, as the damage done by the Mallet scales with the Juggernaut's own damage done to it. Simply throw the Mallet down, use Metronome, and then crouch in rhythm to gain the Nocturne stealth buff, causing the Juggernaut to focus all attacks on the Mallet (this works best while solo).
Can be procced with Radiation damage.
Can be procced with Slash damage, which bypasses the Juggernaut's armor and deals full damage.
Resource boosters do not affect the materials dropped by the Juggernaut, but Desecrate will cause it to drop an additional material piece while also providing a second chance at the Pherliac Pods Blueprint.
Donning the extra protection of Valkyr's Hysteria or Rhino's Iron Skin can help players fight the Juggernaut within its normally intimidating close range.
Does count as a kill objective in Exterminate missions.
Its roar breaks the effects of Mind Control on nearby Infested.
If the player manages to stay hidden after killing all nearby Infested, the Juggernaut will enter an unalerted state. The Juggernaut is susceptible to stealth finisher attacks which can potentially kill the monster in a single strike with a strong enough weapon. If the Juggernaut survives a stealth finisher, the player can evade its detection and repeat the process. ^{[citation needed]}
The demolisher version of the juggernaut has the weak point on its back always open.

Trivia

The Juggernaut is based on the Juggernaut Behemoth, which was the last of the winning entries of the Enemies of the Tenno contest to be implemented into the game, and was designed by player SilverBones, who also designed the Silva & Aegis melee weapon.

Bugs

After the Juggernaut's first roar, sometimes all Infested units will have the orange aura for the rest of the mission.
The Demolisher Juggernaut's Codex entry does not list an armor type for it, despite it having ferrite armor.
The Deimos Juggernaut drop chance for Pherliac Pods is still Hotfix 29.0.7 (2020-09-03) at 90%, even due to the Hotfix stating a nerf to 5%.
Resource booster does not effect Pherliac Pods, Chitinous Husk, Infected Palpitors or Pulsating Turbercles drops.

Media

First roar announcing the Juggernaut:

Lotus announcement:

"A Juggernaut nearby? It will only attack when it senses high concentrations of Infested blood. Slow the fight if you want it to go away."

"That is a Juggernaut. They are lured out by the death of Infested. Lay low and it should go away. Or amp up the fight to draw it out."

Second roar announcing the Juggernaut:

Spawn:

"The Juggernaut. I think you made it angry. Good work."

"That did it. Here comes the Juggernaut."

Juggernaut gone:

"I am no longer detecting signs of a Juggernaut. Move on, you are safe."

"The Juggernaut has moved on. It is safe to proceed."

Patch History

Hotfix 36.0.1 (2024-06-19)

The Juggernaut will now use its stomp ability if it detects perception actions from invisible players (ex: shooting while invisible in Ash’s Smoke Screen).
- This applies to all versions of the Juggernaut, including the Juggernaut Behemoth.

Update 36.0 (2024-06-18)

Reduced the damage of the Juggernaut’s ranged spine strike.
- The amount of Toxin Status Effects it caused could be difficult for newer players to tackle, so we’ve reduced it to make it more manageable.

Hotfix 31.5.2 (2022-04-28)

Fixed script error related to Juggernaut.

Update 31.0 (2021-12-15)

Fixed Juggernaut's stomp attacks no longer spawning new enemies.

Update 29.5 (2020-11-19)

Increased the Deimos Juggernaut variants Affinity gain to 500.
- This was done to be more consistent with the Deimos Saxum variants.

Hotfix 29.0.7 (2020-09-03)

Reduced drop chance of Pherliac Pods Blueprint for Deimos Juggernaut to 5%.

Hotfix 28.0.5 (2020-06-17)

Update 18.7 (2016-03-30)

Balanced the Juggernaut to be more manageable in high-level Infested missions, particularly Infested Sorties. The Juggernaut's level will never exceed 80, and there is now a cap on the number of reinforcements that the Juggernaut can spawn during the stomp attack. The Juggernaut is also limited to one spawn per mission.

Hotfix 16.7.2 (2015-06-05)

Reduced the effectiveness of Crowd Control abilities solely on the Infested Juggernaut.
