Combined from DmgFireSmall64.png Heat and DmgToxinSmall64.png Toxin damage. Most effective against most Infested. Gas status creates clouds that damage the target and other nearby enemies over a short duration.
—In-game Description

DmgGasSmall64.png Gas Damage is one of the six secondary elemental damage types, composed of DmgFireSmall64.png Heat and DmgToxinSmall64.png Toxin elements. It is particularly effective against light Infestation w.svg Infested types, but deals lower damage to IconCorpusOn.png Corpus and IconGrineerOn.png Grineer bodies.

Status Effects[]


The status effect of DmgGasSmall64.png 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 DmgGasSmall64.png 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, potentially allowing headshot bonuses to apply twice (which is also affected by the added headshot damage from Mod TT 20px.png Target Acquired and zoom bonuses on some sniper rifles).

For example, tick damage for a weapon with an innate 100 damage, Mod TT 20px.png Serration, Mod TT 20px.png Thermite Rounds, Mod TT 20px.png Infected Clip and Mod TT 20px.png Bane of Grineer will be:

Modded Damage = 100 × (1 + 1.65) × (1 + 0.3) = 344.5
Tick Damage = 0.5 × 344.5 × (1 + 0.3) = 223.925

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, DmgGasSmall64.png Gas will continue to tick damage on all enemies caught in the host's radius for its remaining duration.

A DmgGasSmall64.png Gas proc briefly creates a dark green cloud on the afflicted.

DmgGasSmall64.png 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.

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.

  • Gas damage, with its brown color and its extra lethality to most Infested, is likely a reference or callback to Enferon, a gas that is described as far more dangerous to Infested creatures than uninfected humans in Digital Extremes' earlier title, Dark Sector.


Patch History[]

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.
