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 + Toxin Damage) ÷ 2, then does 9 ticks of damage over 8 seconds each equal to Toxin Damage. Multiple instances of the effect can stack on the same target with each instance having its own timer.

Because the Gas b Gas proc includes the weapon's modded Toxin b Toxin damage, emphasizing on Toxin b Toxin mods will have a greater effect than Heat b Heat mods. 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.

For weapons dealing Gas b Gas damage without any Toxin b Toxin mods, the proc will instead deal 1/4 of the base damage per tick. This is only possible for weapons with innate Toxin b Toxin damage using Heat b Heat mods and no Toxin b Toxin mods, or for weapons with innate Gas b Gas damage like the Zakti.

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 compensates 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, completely nullifying this element's use against the Infested.
