Eximus units are a category of special 'elite' variants of standard enemies introduced in Update 12.0 that can appear in any mission type. They come in several varieties, each with unique abilities (some of which are similar to Tenno abilities) and are usually much stronger than an average member of their faction, although effects vary from type to type. Eximus units spawn 10-15 ranks higher than the rank average for the mission at hand, along with the highest increase in stats and resistances, posing a reasonable challenge for under-equipped or inexperienced Tenno.

Almost any base unit type (Osprey, Lancer, MOA, etc.) can spawn as an Eximus, though certain units can only spawn as a particular Eximus type, e.g. Chargers can only spawn as Parasitic Types. They can easily be identified by their special auras and larger sizes, and frequently have unique textures/skins to make them more visually distinctive.

All Eximus units were given their own Codex log, essentially doubling the Codex library. Some factions may have only a certain type of Eximus that the others do not have, such as how Shock and Blitz Eximus are exclusive to Corpus units. Additionally, all Eximus-type units have a chance to drop components for the OberonIcon272 Oberon Warframe when defeated. 

Upon death, Eximus units provide 450 - 500 additional base affinity gain of their regular counterparts, before calculated by their level differences.

Eximus TypesEdit



Blitz Eximus shockwave ability

Defends itself with a radial Blast Attack.

Blitz Eximus units are capable of casting Seismic Shockwave, which knocks down nearby opponents. Eximus of this type have an innate resistance of 50% to all damage types, added additively from all three of their healthshield, and armor types.

Blitz Eximus are exclusive to the Corpus, mainly appearing on all models of MOAs and some Crewmen.

Energy Leech / ParasiticEdit

A tank which drains Energy from nearby enemies.

Energy Leech/Parasitic units are capable of draining players' energy within 15 meters at the rate of 5s−1 (does not stack). These Eximus are commonly close combat units such as Corpus Prod Crewmen and Grineer Butchers, as well as the Corrupted versions of the latter. Infested Energy Leech Eximus units use the prefix Parasitic Eximus and are extremely common among all types of Infested. Eximus of this type have 300% of their base health and shield and an innate resistance of 50% to all damage types, added additively from all three of their health, shield, and armor types.

Arson / Caustic Edit

Heat based attacks and auras

Arson/Caustic Eximus units project a fire resistance aura to their nearby allies, which nullifies all Heat b Fire damage; this aura also extends to combined elemental damage and will nullify the Heat b Fire damage of combined types utilizing it. They have the ability to release a Fire Blast similar to the one used by EmberIcon272 Ember or General Sargas Ruk. However, the Eximus's blast is concussive rather than elemental, knocking down and damaging any enemies who are caught in the blast, but not applying aHeat b Fire proc. The knockdown can be negated by blocking with a melee weapon or rolling. Eximus of this type have an innate resistance of 50% to all damage types, additive to all three of their health, shield, and armor types.

These Eximus units will release their fire wave when enemies are close to them and are capable of dealing significant damage to Sentinels at higher levels; caution is advised when engaging them at close range.

The Infested uses the prefix Caustic instead of Arson, and behave largely the same and are capable of releasing a Fire Blast. This Eximus variety is common among Grineer, including Corrupted versions. Corpus only have access through the archwing Corvette enemy type.



Guardian Eximus shield restore ability

Restores shields of nearby allies.

Guardian Eximus units are especially durable, gaining a significant boost to their own shields as well as the mentioned shield-restoration effect. They release a radial shield charge in a blue-grid restorative pulse. Eximus of this type have an innate resistance of 50% to all damage types, added additively from all three of their health, shield, and armor types.

Guardian Eximus units are exclusive to the Corpus (and their corresponding Corrupted counterparts), which should be of little surprise given their fairly extensive use of shields. Eximus units of this type are usually MOAs, Orokin Drones, and Ospreys.



Arctic Eximus Post Rework

Cold based attacks and auras.

Arctic Eximus units project a cold resistance aura to their nearby allies, which nullifies all Cold b Cold damage; this aura also extends to combined elemental damage types and will nullify the Cold b Cold damage of said combined type. This aura also deals a continuous Cold b Cold status effect to the Arctic Eximus' foes, greatly reducing their movement and attack speed, even through status immune abilities like WardingHalo130xDark Warding Halo and IronSkin130xDark Iron Skin. They can generate a temporary SnowGlobe130xDark Snow Globe barrier to protect themselves and allies. Their version follows them when they move as opposed to being stationary like FrostIcon272 Frost's, and has a unique and distinctive design of a white/blue transparent sphere with ice rings around it. They have additional ice-based attacks as well. Eximus of this type have an innate resistance of 50% to all damage types, added additively from all three of their health, shield, and armor types.

Arctic Eximus units are among the most dangerous variety, as their ice slowdown aura is fairly large, while their snowglobe protects them from ranged attacks. Certain targeted powers, like OberonIcon272 Oberon's Smite130xDark Smite and VoltIcon272 Volt's Shock130xDark Shock, can damage the target through the snowglobe. Like the regular Snow Globe, inflicting enough damage will cause the Arctic Eximus's Snow Globe to disintegrate. Note however that the globe has object-based health and is not affected by critical damage, rendering crit-focused weapon less effective than raw damage weapons. The globe also dissolves by itself after a certain amount of time, therefore hiding in cover and waiting for the globe to dissipate is an alternative tactic. Multiple Arctic Eximus are especially dangerous, as their slowdown aura stacks with one another, which can slow the player down to a crawl.

This unit variant is reasonably common amongst the Grineer and Corpus (including Corrupted versions of both), but nonexistent among the Infested.

It is possible for Grineer Napalms and Scorches to spawn as Arctic Eximus. If the player suffers a fire proc while within the Eximus's aura, the fire proc changes to a Blast proc (possibly a bug, imperfect chance of happening).

Leech / SanguineEdit

Life leech weapon, enhanced health.

Leeches and Sanguines regenerate health by inflicting damage to their enemies. This is easily observed after damaging them as they will regain health from damaging a target's shields/health, or a target that has IronSkin130xDark Iron Skin active. Eximus of this type have 300% of their base health and shield.

Leech Eximus units are common in Grineer ranks, but are nonexistent in the Corpus. Corrupted Eximus can also spawn in this variant. Infested Eximus units use the Sanguine prefix instead of Leech, but otherwise behave identically. This should not be mistaken for the Energy Leech prefix noted above.


Electric based attacks and auras.

Shock Eximus units project an electric resistance aura on their nearby allies which nullifies all Electricity b Electricity damage. This aura also extends to combined elemental damage and will nullify the Electricity b Electricity damage of said combined type. They also emit an Electricity b Electricity status effect aura that affects all enemies within a 5 meter radius – players within a 2 meter radius will take damage at a steady rate. The effect is constant until the Eximus is defeated or until the Tenno moves out of range. Eximus of this type have an innate resistance of 50% to all damage types, added additively from all three of their health, shield, and armor types.


Toxin based attacks and auras.

Venomous Eximus units project a toxin resistance aura to their nearby allies, which nullifies all Toxin b Toxin damage, this aura also extends to combined elemental damage and will nullify the Toxin b Toxin damage of said combined type. They are capable of delivering Toxin b Toxin attacks towards their enemies and also have the ability to emit a potent toxin aura in a 10 meter range. When inflicted, an 8 second Toxin b Toxin proc will persist and deal moderate damage over time, depending on the level of the enemy which inflicted the proc. Venomous Eximus most commonly appear among the Infestation (such as Ancient and Mutalist enemy types), however Grineer have Tusk Butcher and Dargyn Eximus, the Corpus only have Venomous Eximus units in archwing with their Rangers. Eximus of this type have an innate resistance of 50% to all damage types, added additively from all three of their health type, shield type and armor type.

Special Eximus TypesEdit

Synthesis TargetEdit

Classified as an eximus, a Synthesis target is a marked target for Cephalon Simaris. Synthesis targets have far more health than their regular counterparts (preventing players from killing them accidentally, though it is possible for players to kill them regardless), and have at least 3 nodes visible through the Synthesis Scanner. Scanning at least one node will cause the Synthesis target to run away from the player and gain a random special ability to evade capture, like leaving a trail of Magnetic b Magnetic clouds.


Main article: Guardsman

A unique variant of Eximus unit exclusively for the Grineer Guardsmen, that provides near invulnerability to itself and to its allies while remaining vulnerable to a single primary elemental damage type. Eximus types vary between Shock, Fire, Ice, and Toxic.


Life Leech weapon, increased speed, weak to stealth attacks.

A special Eximus variant of the Wardens introduced in Rescue missions, featuring Life Leech and enhanced movement speed. However, they are extremely vulnerable to stealth attacks, and will most times receive fatal damage from it.

Sensor RegulatorEdit

A unique Eximus variant of the Sensor Regulator that was introduced circa Update 18.0. These Sensor Regulators have 100% additional armor, and 200% additional health, making them far more durable than a normal Sensor Regulator. These Regulators are more likely to spawn in Sorties.

Orokin SpectatorEdit

Similar to Sensor Regulator, a unique Eximus variant of the Orokin Spectator that was introduced circa Update 18.0. These Orokin Spectator have 100% additional armor, 200% additional health, and 50% additional shield, making them far more durable than a normal Orokin Spectator. These Spectators only spawn in Spy missions at Lua as well as Sorties.

  • The bonus damage resistance for Eximus units has a cap, which stacks up to 90% at maximum for any type of damage.
    • Most Eximus types have 40% damage resistance against True damage as well.
  • Eximus units can drop affinity or Health orbs on death.
  • Eximus units also appear in the codex since Update 13.0. They are classified according to their unit type (i.e. Lancer Eximus rather than Arson Eximus), with all possible leader variations of that particular unit being available within their entry.
    • When scanning for Eximus, one scan counts as their Unit type, not their Eximus type. For example, scanning 3 Lancer Arson Eximus and 3 Lancer Arctic Eximus counts as 6 scans out of 20 in the Lancer Eximus entry. It is thus unnecessary to scan each Eximus type individually.
  • As of Update 13.7, Eximus enemies under MindControl130xDark Mind Control will focus their attacks on enemies instead. They will still be able to use abilities unique to certain Eximus variants, but these will not damage allies during the power duration. Unknown if allies will gain additional elemental damage from elemental Eximus or if other enemies will have negative elemental effects.
  • As of Hotfix 12.4.2, some Eximus types seem to spawn with a small group of up to about ten normal units around them, which can be quite burdensome on game modes like Interception or Survival, as this causes too many enemies to spawn.[citation needed] More research needed on the leader/minion counts.
  • Corrupted Eximus units can also spawn in the Void, but were temporarily removed from Update 13.0 until Update 13.7 for unknown reasons.
  • Update 13.7 increased the spawn rate of Eximus enemies in Survival, gradually increasing to up to 20% at 60 minutes. On Infested survival, this can cause players to be overwhelmed by several Eximus at once during the entire mission due to Infested having a higher spawn and rushing rate.
  • As of Update 20.6. Eximus units can be resurrected with ShadowsOfTheDead130xDark Shadows Of The Dead, allowing the stacking of multiple Eximus collected consecutively by NekrosIcon272 Nekros.
  • Eximus units cannot be resurrected with InarosIcon272 Inaros's Devour130xDark Devour, in which the targeted Eximus simply dies without producing a Sand Shadow.
  • Some Eximus units gain heavy resistance to damage that normally would deal extra damage to their normal variant. A good example is an Eximus Leaper which becomes resistant to both Heat b Fire and Slash b Slash damage, and only is slightly weak to Gas b Gas damage.
  • Toxic Ancients are the only enemy that when MindControl130xDark Mind Controlled or when a Shadow, give the player bonus damage, in the form of Toxin b Toxin. A non-Eximus Toxic Ancient will grant nearby allies 40 Toxin damage, whereas a nearby Venomous Toxic Ancient will grant nearby allies about 53 toxin damage. While not massively useful, it does mean it will combine with single elementals on your weapons, allowing damage types such as Gas b Gas or Viral b Viral to be made..


  • According to the Nightwave task Eximus Executioner (Kill x Eximus), the plural of Eximus is Eximus.
  • Before Update 13.0, most Eximus had different prefixes; Blitz used to be called Blast; Arson used to be called Fire; Arctic used to be called Ice; Leech used to be called Lifesteal; and Shock used to be called Mag.
    • For that matter, Shock Eximus used to emit a Magnetic b Magnetic aura, draining the energy and shields of any Warframe that got too close. This feature was rendered inert from the Cold Revenge Tactical Alert to Hotfix 18.5.1, before the developers changed the aura to Electricity b Electric instead.
  • Before Update 13.0, Eximus were referred to as Leader units.
  • Up until Update 13.0The Sergeant could spawn as an Eximus, quadrupling his affinity and greatly increasing his health.
  • According to Digital Extremes[citation needed] , Eximus are the result of the following;
    • Corpus Eximus Crewmen are members of the elite who are bestowed specially-designed suits, whereas MOA and Osprey Eximus are produced on a regular basis.
    • Grineer (barring Rollers) and Infested Eximus are the products of genetic mutation, though in the case of the Infested, the genes that contain said mutations are present in the DNA of all known Infested, suggesting that some form of gene expression regulation is in effect.
      • Although no explanation was given for Roller Eximus, it's likely they are produced much like MOA and Osprey Eximus.
    • Corrupted Eximus are simply corrupted versions of the above units.


  • Some Eximus units require the same amount of Codex scans as their original variant to complete their entry, as opposed to only requiring three Codex scans. This usually occurs when new enemies are put into the game and is usually fixed shortly afterward.

Patch HistoryEdit

Hotfix 27.0.9
  • Fixed magnetic proc sound playing repeatedly on Shock Eximus Auras.

Hotfix 25.1.1

  • Fixed most Auras not reacting to changes in Rift-Status:
    • Banishing an Eximus enemy will remove its Aura from enemies out of the Rift, eg: if you Banish a Venomous Eximus and stay out of the Rift it won't be able to hit you with its Toxin Aura, or if you Banish an Ancient Healer it won't be able to protect its allies left behind.

Update 24.6

  • Reduced the visual thickness of the Arctic Eximus’ Snow Globe barrier.

Update 20.6

  • 'Nekros' Shadows of the Dead can now summon Eximus units! This fixes the issue of Nekros being unable to summon Eximus units at all.

Hotfix 18.5.6

  • Changed Shock Eximus auras to proc with Electric Damage instead of Magnetic. Now all 4 raw elements are represented in Eximus Units.
