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.

Gas b Gas damage's status effect is Toxin Cloud, which produces small toxin cloud that deals Toxin b Toxin damage (notably not Gas b Gas damage) to all enemies within its 3-meter radius. The cloud deals immediate damage on proc equal to (Base Damage / 2) * (1 + Toxin Damage), then itself procs Toxin b Toxin status, dealing 9 ticks of damage over 8 seconds each equal to (Base Damage / 4) * (1 + Toxin Damage)². Multiple instances of the effect can stack on the same target with each instance having its own timer.

Because the Gas b Gas proc is strengthened by Toxin Damage,  Toxin b Toxin mods also help to increase proc damage; in contrast, Heat b Heat mods will merely increase the proc bias toward Gas b Gas without increasing the procs' damage. If a proc occurs together with a headshot, stealth bonus, and/or critical hit, the ticks are also affected by their respective multipliers. However, innate Toxin b Toxin damage from weapons such as the Paracyst does not contribute to the damage-over-time ticks.

Because the damage from this status effect is Toxin b Toxin and not Gas b Gas, it can bypass Shields/Proto Shields and deal increased damage against Flesh and Ferrite Armor enemies, which can help compensate for Gas b Gas's damage penalty against Corpus Flesh and Grineer Cloned Flesh.

Although effective against light Infested units, the status effect's Toxin b Toxin damage is reduced against Fossilized units. In addition, a Toxic Ancient produces an aura to its allies that provides 100% damage reduction to Toxin b Toxin and 80% damage reduction to Gas b Gas, neutering this element against the Infested while the aura is in effect.
