Combined from Heat b Heat and Toxin b 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

Gas b Gas Damage is one of the six secondary elemental damage types, composed of Heat b Heat and Toxin b Toxin elements. It is particularly effective against light Infestation bInfested types, but deals lower damage to IconCorpusBCorpus and IconGrineerBGrineer bodies.

Status EffectsEdit


The status effect of Gas b 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 b Gas damage equal to 0.5 × Modded Damage × (1 + Faction Damage bonus). As can be seen from the formula, tick damage does not scale with any Elemental mods. Multiple instances of the effect can stack on the same target, with each instance having its own timer.

For example, tick damage for a weapon with an innate 100 damage, Mod TT 20pxSerrationMod TT 20pxThermite Rounds, Mod TT 20pxInfected Clip and Mod TT 20pxBane 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, Gas b Gas will continue to tick damage on all enemies caught in the host's radius for its remaining duration.

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


Gas b Gas does not have an Empyrean counterpart and is thus not able to proc any status effect nor is it included in calculations for status proc weighting.

  • 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 HistoryEdit

Update 27.3

  • 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

  • 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.
