STATUS EFFECT
Created by combining  Heat and  Toxin damage.

 Gas produces gas clouds that deal damage to all enemies within a 3 meter radius for a short duration.
—In-game Description

 Gas Damage is one of the six secondary elemental damage types, composed of  Heat and  Toxin elements. Deals increased damage to Infested Deimos and Techrot enemies but reduced damage against Scaldra enemies. Its Status Effect creates a damaging cloud.

Status Effects[]

General[]

The status effect of  Gas damage is Gas Cloud. It produces a gas cloud that deals a tick of damage each second to all enemies within a 3-meter radius; subsequent procs increase the radius by 0.3 meters up to 6 meters in total after 10 stacks. The cloud has a 6 second duration. Each tick deals  Gas damage equal to:

Notice that modded base damage calculation used for DoT is not the same as normal damage calculations, ignoring physical and elemental damage bonuses.

Additional Multipliers include modded critical multiplier on Critical Hit and multipliers on Enemy Body Parts; these stack multiplicatively with each other.

As can be seen from the formula, tick damage does not scale with any Elemental mods. Up to 10 instances of the effect can stack on the same target, with each instance having its own timer. Any instances after the 10th will replace the oldest instance.

The Gas Cloud is able to hit heads and other body parts by itself. However, the Gas Cloud itself has a 1x damage bonus when headshotting. This can be increased with the use of mods such as  Target Acquired, zoom bonuses on some sniper rifles, or  Primary Deadhead/ Secondary Deadhead.

For example, tick damage for a weapon with an innate 100 damage,  Serration,  Thermite Rounds,  Infected Clip  Bane of Grineer, and  Rifle Elementalist will be:

Modded Damage = 100 × (1 + 1.65) × (1 + 0.3) = 344.5
Tick Damage = 0.5 × 344.5 × (1 + 0.3) × (1 + 0.9) = 425.4575

As can be seen in the above calculations for tick damage, Faction Damage is applied twice, making their effective bonus = (1 + Faction Damage bonus)2. Which is +69% for the 30% Faction Damage mods and +140.25% for the 55% Primed Faction Damage mods.

If the host target dies,  Gas will continue to tick damage on all enemies caught in the host's radius for its remaining duration.

A  Gas proc briefly creates a dark green cloud on the afflicted.

Railjack[]

 Gas does not have a Railjack space counterpart and is thus not able to proc any status effect nor is it included in calculations for status proc weighting.

Erupt with a multitude of Eidolon energy beams and sweep a circle of death around Revenant. The beams will modify their Damage Type to target select defenses, while incoming damage is redirected back into the beams. Hold fire to boost Status Effects and Damage, at the cost of increased energy consumption. Thralls killed by this leave overshield pickups.

Trivia[]

  • Gas damage, with its brown color, damage over time, and its extra lethality to most Infested, is likely a reference or callback to Enferon, a gas that is highly lethal to creatures infected by the Technocyte Virus but not uninfected humans in Digital Extremes' earlier title, Dark Sector.

Patch History[]

Update 37.0 (2024-10-02)

  • Fixed Gas damage’s radial damage bubble VFX disappearing after hitting 10 stacks on the target.
    • It should now only disappear after all Gas stacks have expired.

Update 36.0 (2024-06-18)

Simplified Faction Resistances
  • Deimos Infested:
    • Vulnerable to Gas
Status Effect Reworks

Gas

Gas often lacked effective readability, making it difficult to distinguish its presence from the enemy or yourself. We’ve introduced enhanced visuals so that when the Gas Status Effect is active, you’ll be able to recognize it more clearly.

Gas Changes:

  • Added VFX on top of the target affected by a Gas Cloud to clearly show an effect is active.
    • In addition to current and new VFX, Gas VFX now also more clearly shows the radius of the Gas Damage-over-Time (DoT) effect around a given target to better understand its impact on surrounding enemies.
      • If a player is inside the radius of the Gas DoT, the visuals are reduced for them to maintain visibility, similar to Frost’s Snow Globe.
  • Gas VFX now has billowy volume to better present presence.
  • Gas VFX now has additional floating particles around the smoke.

Update 33.5 (2023-06-21)

  • Fixed a rare crash that could occur when using Enemy Radar and weapons that create Gas Status Effects.

Update 27.3 (2020-03-24)

  • Gas Effects will continue to tick radial Damage-over-Time for the average of the remaining Effect duration if their host dies.
  • Gas Status Area-of-Effect radius increases with the number of stacks, to a max of 10 stacks.
  • Removed Gas damage resistance from Toxic Ancient Auras.

Update 27.2 (2020-03-05)

  • The base duration of a Gas Status Effect now matches Slash for 6 seconds. No longer does AoE with forced Poison Status Effect (resulting in Poison DoT for enemies in radius), instead it does AoE DoT Gas damage around the target.

Update 11.0 (2013-11-20)

  • Introduced.
