Gas Damage is one of the six secondary elemental damage types, composed of 
Heat and 
Toxin elements. It is particularly effective against light 
Infested types, but deals lower damage to 
Corpus and 
Grineer bodies.
Status Effects
Edit
Gas damage's status effect is Toxin Cloud, which produces small toxin cloud that deals Toxin damage (notably not Gas damage) to all enemies within its 3-meter radius. The cloud deals immediate damage on proc equal to Base Damage × (Toxin Mod Multiplier ÷ 2), then itself procs Toxin status, dealing 9 ticks of damage over 8 seconds each equal to Base Damage × (Toxin Mod Multiplier ÷ 2)2. Multiple instances of the effect can stack on the same target with each instance having its own timer.
Because the Gas proc is strengthened by Toxin Damage, Toxin mods also help to increase proc damage; in contrast, Heat mods will merely increase the proc bias toward 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 damage from weapons such as the 
Paracyst does not contribute to the damage-over-time ticks. It should also be noted that due to the nature of Faction damage mods, their bonuses are applied thrice during the calculation of Toxin Cloud damage per tick. For example, the Toxin Cloud damage per tick of a weapon with an innate 100 damage, 
Serration, Infected Clip, and Bane of Grineer will be:
- Base Damage = 100 × (1 + 1.65) × (1 + 0.3) = 344.5
- Toxin Mod Multiplier = (1 + 0.9) × (1 + 0.3) = 2.47x
- Toxin Cloud Damage per tick = 344.5 × (2.47 ÷ 2)^2 = 525.44
Because the damage from this status effect is Toxin and not Gas, it can bypass Shields/Proto Shields and deal increased damage against Flesh and Ferrite Armor enemies, which can help compensate for Gas's damage penalty against Corpus Flesh and Grineer Cloned Flesh.
Although effective against light Infested units, the status effect's 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 and 80% damage reduction to Gas, neutralizing this element against the Infested while the aura is in effect.
