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[edit | edit source]

  • 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. If the player does not wish for the Juggernaut to spawn, they may simply avoid combat until it moves on.
    • The Juggernaut's Roar will also disable active powers like MindControl130xDark.pngMind 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 TrinityIcon272.pngTrinity's EnergyVampire130xDark.pngEnergy Vampire. Percentage based damage such as DmgSlashSmall64.pngSlash completely bypasses the Juggernaut's armor.

Farming Locations[edit | edit source]

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.

Target Planet Name Type Level Tile Set
IconInfestedB.svg Eris Saxis Exterminate 34 - 38 Infested Ship
IconInfestedB.svg Eris Isos Capture 32 - 36 Infested Ship
IconInfestedB.svg Europa Armaros Exterminate 18 - 20 Infested Ship
IconInfestedB.svg Deimos Horend Capture 12 - 14 Orokin Derelict
EntratiIcon.png Deimos Cambion Drift Free Roam 20 - 35 Cambion Drift
  • Juggernaut spawns reliably on Isos, Eris and Armaros, Europa. 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.
  • Armaros, Europa is a low-level mission with common Juggernaut spawns. Within 20 consecutive test runs, all 20 yielded a Juggernaut spawn. Furthermore, of those 20, 19 of them roared within the first minute of the mission. However, this is all anecdotal evidence and requires further test runs before any conclusions should be drawn.
  • 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.

Damage Resistance[edit | edit source]

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.

  • DmgSlashSmall64.pngSlash 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

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.

Notes[edit | edit source]

  • Can be chained with HarrowIcon272.pngHarrow's Condemn130xDark.pngCondemn.
  • Can be affected by BansheeIcon272.pngBanshee's Sonar130xDark.pngSonar to deal additional damage, making it much easier to deal much more damage while its maw is closed.
  • Can be put to sleep by IvaraIcon272.pngIvara's sleep arrows, although for minimal duration.
  • Can be resurrected and enthralled by NekrosIcon272.pngNekros' ShadowsOfTheDead130xDark.pngShadows Of The Dead.
  • Can become mind controlled by NyxIcon272.pngNyx, although for minimal duration.
  • Ash's Mod TT 20px.pngSeeking Shuriken augment and a Kavat's Sharpened Claws will both strip a Juggernaut's armor.
  • NidusIcon272.pngNidus's Virulence130xDark.pngVirulence seems to bypass the Juggernaut's armor.
    • The InfestedLongGunTwo.pngPhage will also somewhat bypass it, dealing minor damage over time.
    • TeshinGlaive.pngOrvius's channeling thrown attacks will also ignore Juggernaut's armor.
  • MirageIcon272.pngMirage's HallOfMirrors130xDark.pngHall 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.
  • OctaviaIcon272.pngOctavia's Mallet130xDark.pngMallet 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 Amp130xDark.pngMetronome, 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 DmgRadiationSmall64.pngRadiation damage.
  • Can be procced with DmgSlashSmall64.pngSlash damage, which bypasses the Juggernaut's armor and deals full damage.
  • Resource boosters do not affect the materials dropped by the Juggernaut, but Desecrate130xDark.pngDesecrate 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 ValkyrIcon272.pngValkyr's Hysteria or RhinoIcon272.pngRhino'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 MindControl130xDark.pngMind 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[edit | edit source]

Bugs[edit | edit source]

  • 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 29.07) at 90%, even due to the Hotfix stating a nerf to 5%.

Media[edit | edit source]

  • First roar announcing the Juggernaut:
  • "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."
