Damage/Gas Damage

Damage is one of the six secondary elemental damage types, composed of and  elements. It is particularly effective against light Infested types, but deals lower damage to Grineer and Corpus bodies.

damage's status effect is Poison Cloud, which applies two separate instances of damage (notably, not  damage) on the target and all enemies within 5 meters of the target:
 * 1) Immediate damage equal to ( + )/2.
 * 2) 9 ticks of damage over 8 seconds, each equal to 125% of the weapons total  damage.

Because both instances of the proc include the weapon's  damage, emphasizing on  mods will have a greater effect than  mods.

Multiple instances of the effect can stack on the same target with each instance having its own timer.

Base damage mods and combo multipliers will also increase the damage of gas ticks and if the proc occurs together with a headshot and/or critical hit, the gas ticks are also multiplied by a headshot multiplier and/or critical damage multiplier respectively. In case of melee weapons, another 8x stealth damage multiplier is applied to the gas ticks if the Warframe is in a stealth state. Because the damage from this status effect is and not, it can bypass Shields / Proto Shields and deal increased damage against Ferrite Armor enemies which compensates for the damage penalty against Corpus Flesh and Grineer Cloned Flesh up to a certain degree.
