Heavy melee unit surrounded by poison cloud.

An Infested heavy melee unit, the Toxic Ancient stands out for the ability to grant nearby allies a toxic aura, granting them DmgToxinSmall64.png Toxin damage as well as a large resistance to DmgToxinSmall64.png Toxin damage. Along with their toxic aura, these Ancients possess the ability to excrete a deadly toxic cloud when they do their "roar" animation, dealing heavy DmgToxinSmall64.png Toxin damage that can easily kill players caught in the radius.

Toxic Ancients can be identified by the bright green glow from their heads, as well as their black and green bodies.


  • The crown on its back is a special body modifier that reduces damage by a flat 50%.
  • The Toxic Ancient's aura gives itself and all nearby enemies 25% DmgToxinSmall64.png Toxin damage. In addition, the aura provides 80% damage reduction to DmgToxinSmall64.png Toxin.
    • Multiple Toxic Ancient auras stack additively.
  • On sight of an enemy, the Ancient will roar to threaten enemies, similar to other Ancients. This roar will release a toxin cloud and deal heavy DmgToxinSmall64.png Toxin damage over its duration in a short cone in front of the Ancient, with lethal consequences for enemies with low health that are too close to it.
  • Toxic Ancients, like the other Ancients, will continue to pursue their targets if they have detected them, then chased after, even if these targets have turned invisible (Shade's Mod TT 20px.png Ghost etc.).
  • If Sentinels are used in missions, be cautious, as the fumes created by the Toxic Ancients are much more likely to cause significant damage to them, killing them almost instantly in some cases.
  • They will occasionally deploy grappling hooks to reel in players into melee range, identical to that used by Grineer Scorpions, although more deadly with this Ancient as the hook will include shield-ignoring DmgToxinSmall64.png Toxin damage as well.


  • The grappling hook has a 1 second delay before being reeled back and inflicting Knockdown b.png Knockdown. During this time the player can cut the rope with a melee attack, or bullet jump or roll which will cause the Toxic Ancient to be dragged along.
  • If converted into an ally such as MindControl130xDark.png Mind Control, the Ancient will buff Tenno's resistance to toxin effects as well as 25% DmgToxinSmall64.png Toxin damage to weapons which will combine with "loose" single elementals like DmgColdSmall64.png Cold to create DmgViralSmall64.png Viral.
  • The presence of a Toxic Ancient can damage a cryopod on defense missions, as small amounts of damage from all Infested nearby will ignore the shields of the cryopod.
  • If a Tenno enters stealth while an Ancient is charging into attack range and remains in the same position, the Ancient's first attack will still connect but it will not continue to attack until its target becomes visible again. This may actually be counterproductive for the Toxic Ancient as the attack will often knock the invisible Tenno out of poison range.
  • By equipping ArcaneResistance.png Arcane Resistance, there is a significant chance to prevent Toxin status effects.
  • An Ancient under the effects of a Radiation proc will have their aura's effect temporarily disabled to its allies although the effect will still be negatively applied to players.


  • As of Update 11.0 (2013-11-20), Toxic Ancients do not leave poison clouds in places where they recently died.
  • According to the Lotus, the Ancients are a plant-like lifeform.[citation needed]
  • The pre-Update 9.0 (2013-07-13) color scheme of the Toxic Ancient is the current color scheme of the Toxic Crawler.


Patch History[]

Update 31.6 (2022-06-09)

Enemy Grappling Hook Rework:

Ancients have had their grappling hook mechanic reworked! An age-old enemy mechanic from the early beginnings of Warframe, they’ve been grappling Tenno left and right for years - it’s time to break free! Since its introduction, the grappling hook attack has consistently knocked players down or dragged them around, providing no opening for combative counterplay.

NOW Ancient grappling hooks will tether to you, followed by a slight delay (1 second) before they attempt to slowly pull you in. Tenno who are agile enough can now Melee attack in the direction of the rope to destroy it and stagger the enemy. Additionally, Bullet Jumping or dodging during the pulling animation can cause a stagger to the enemy.

Hotfix 31.1.3 (2022-02-15)

  • Defeated Infested Ancients’ corpses will now dissolve quicker.

Update 27.3 (2020-03-24)

  • Removed Gas damage resistance from Toxic Ancient Auras.

Hotfix 27.1.2 (2020-02-18)

  • Tweaked Toxic Ancients Area of Effect blast FX timing so the FX is visible before the actual damage (at the moment, you'll always be damaged before you see the attack).

Hotfix 25.1.1 (2019-06-06)

  • 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.

  • Ancient and Scorpion grappling hooks no longer go through Gara’s Mass Vitrify wall.
