STATUS EFFECT
Created by combining  Heat and  Toxin damage.

 Gas produces gas clouds that deal damage to all enemies within a 3 meter radius for a short duration.

—In-game Description

 Gas Damage is one of the six secondary elemental damage types, composed of  Heat and  Toxin elements. Deals increased damage to Infested Deimos and Techrot enemies but reduced damage against Scaldra enemies. Its Status Effect creates a damaging cloud.

Status Effects

General

The status effect of  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 damage equal to:

${ \begin{aligned} \text{Modded Base Damage} &= \text{Base Damage} \times (1 + \text{Base Damage Bonuses}) \times (1 + \text{Faction Damage Bonuses}) \end{aligned} }$

Notice that modded base damage calculation used for DoT is not the same as normal damage calculations, ignoring physical and elemental damage bonuses.

${\begin{aligned}{\text{Gas Proc Damage per Tick}}=\;&0.5\times {\text{Modded Base Damage}}\times (1+{\text{Faction Damage Bonuses}})\\&\times (1+{\text{Status Damage Bonuses}})\times {\text{Additional Multipliers}}\end{aligned}}$

Additional Multipliers include modded critical multiplier on Critical Hit and multipliers on Enemy Body Parts; these stack multiplicatively with each other.

As can be seen from the formula, tick damage does not scale with any Elemental mods. Up to 10 instances of the effect can stack on the same target, with each instance having its own timer. Any instances after the 10th will replace the oldest instance.

The Gas Cloud is able to hit heads and other body parts by itself. However, the Gas Cloud itself has a 1x damage bonus when headshotting. This can be increased with the use of mods such as  Target Acquired, zoom bonuses on some sniper rifles, or  Primary Deadhead/ Secondary Deadhead.

For example, tick damage for a weapon with an innate 100 damage,  Serration,  Thermite Rounds,  Infected Clip  Bane of Grineer, and  Rifle Elementalist will be:

Modded Damage = 100 × (1 + 1.65) × (1 + 0.3) = 344.5

Tick Damage = 0.5 × 344.5 × (1 + 0.3) × (1 + 0.9) = 425.4575

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 will continue to tick damage on all enemies caught in the host's radius for its remaining duration.

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

Railjack

 Gas does not have a Railjack space counterpart and is thus not able to proc any status effect nor is it included in calculations for status proc weighting.

Abilities

• Revenant

	4 25 +20-40/s	Danse Macabre Erupt with a multitude of Eidolon energy beams and sweep a circle of death around Revenant. The beams will modify their Damage Type to target select defenses, while incoming damage is redirected back into the beams. Hold fire to boost Status Effects and Damage, at the cost of increased energy consumption. Thralls killed by this leave overshield pickups.

Info

• Revenant unleashes the might of the Eidolon essence emanating from his left arm, dispersing the Sentient energy into 9 energy beams as he levitates and spins counterclockwise. Energy beams oscillate in angle vertically as Revenant rotates, rapidly sweeping across a 100 meter radius area with rotation speed 1 rev/sec in a pentagonal shape. Each energy beam has a thickness of 0.03 / 0.05 / 0.08 / 0.1 meter radius and continuously inflicts 500 / 750 / 1,000 / 1,250 damage per second with a 20% status chance to all enemies caught in its path.
  • Casting speed is affected by Casting Speed.
  • Energy beams possess innate Punch Through, allowing them to bypass terrain and obstacles in the environment.
  • Energy beams cannot hit enemies standing above Revenant's left arm due to the oscillation pattern.
  • While active, all damage received by Revenant is stored into a total damage pool. The stored damage is displayed as a buff. The current displayed value is added to each beam as a flat damage bonus.
    • Stored damage decays at a rate of ~23.33% current damage per second, which equates to ~39.5% every 2 seconds, ~52.1% every 3 seconds, etc.
    • Damage resisted by  Mesmer Skin is stored, despite not injuring Revenant.
  • Revenant is able to move with reduced movement speed while channeling Danse Macabre. Speed the same as Revenant's running speed (without sprint) and affected only by Hobbled Dragon Key,  Volt's  Speed, and  Wisp's  Reservoirs Haste Mote.
• Holding the fire button (default LMB ) increases the beams' damage per second to 1,000 / 1,500 / 2,000 / 2,500, status chance to 40%, and beam radius to 0.05 / 0.1 / 0.15 / 0.2 meters.
• Energy beams autonomously adapt their damage type to the attributes of the enemies they hit:  Corrosive against armored enemies,  Magnetic against shielded enemies, and  Gas against Infested.
• Danse Macabre costs 25 energy to activate, then consumes 20 energy per second (40 energy per second during the boosted version) while active and will remain active until Revenant's energy is depleted, or the ability is deactivated by pressing the ability key again.
  • Revenant cannot replenish energy using  Energy Vampire,  Rally Point, Rift Plane's innate energy regeneration, Squad Energy Restores,  Energy Siphon,  Energy Nexus,  Dreamer's Bond, and/or  Wellspring while Danse Macabre is active.
  • Energy Orbs, Orokin Void Death Orb's energy restores,  Rage,  Hunter Adrenaline,  Arcane Energize, and  Emergence Dissipate's Energy Motes can still replenish Revenant's energy during Danse Macabre.
  • Danse Macabre's energy drain is not converted into shields by Augur Mods.
• Ability Synergy:
  • Enemies affected by  Enthrall when killed by Danse Macrabe drop a unique pickup that grants 50 Overshields when collected by Revenant or his allies.
  • Enthrall energy pillars explode to inflict damage radially when struck by Danse Macabre lasers.
    • Explosion deals the remaining damage of the pillar to surrounding enemies.
    • Explosion damage diminishes with distance.
  • Damage reflected by  Mesmer Skin also accumulates into Danse Macabre's energy beam damage pool.
  •  Reave costs halved energy during  Danse Macabre, with instantaneous casting speed and Danse Macabre's stopping animation can be skipped if deactivated during Reave.
• Revenant cannot cast Enthrall, Mesmer Skin, subsumed abilities over Enthrall or Mesmer Skin via the Helminth system, perform parkour Maneuvers or general interactions while channeling this ability.
• Revenant can cast Reave or a subsumed ability over Reave via the Helminth system while channeling this ability.
• Revenant is immune to  Knockdown while channeling this ability.
• Casting Danse Macabre is a full body animation that interrupts grounded movement and other actions.
• Revenant visually extends his left arm outward and his right arm upward, as he hovers and rotates in place. Energy beams are generated and spread throughout his left arm, while droplets and gaseous energy particles emit from both hands. When the fire button is held, a surge of Sentient energy resembling Enthrall's energy pillars continuously erupt skyward from beneath Revenant's feet.
• Energy beams, energy particles, and energy surge color tinting are affected by Revenant's chosen Warframe energy color.

Bugs

• Beam punch through is inconsistent, often failing to penetrate terrain to hit enemies in range. No known causes nor workarounds, unfortunately.

Trivia

• Gas damage, with its brown color, damage over time, and its extra lethality to most Infested, is likely a reference or callback to Enferon, a gas that is highly lethal to creatures infected by the Technocyte Virus but not uninfected humans in Digital Extremes' earlier title, Dark Sector.

Status Effect Reworks

Gas

Gas often lacked effective readability, making it difficult to distinguish its presence from the enemy or yourself. We’ve introduced enhanced visuals so that when the Gas Status Effect is active, you’ll be able to recognize it more clearly.

Gas Changes:

• Added VFX on top of the target affected by a Gas Cloud to clearly show an effect is active.
  • In addition to current and new VFX, Gas VFX now also more clearly shows the radius of the Gas Damage-over-Time (DoT) effect around a given target to better understand its impact on surrounding enemies.
    • If a player is inside the radius of the Gas DoT, the visuals are reduced for them to maintain visibility, similar to Frost’s Snow Globe.
• Gas VFX now has billowy volume to better present presence.
• Gas VFX now has additional floating particles around the smoke.

Update 33.5 (2023-06-21)

• Fixed a rare crash that could occur when using Enemy Radar and weapons that create Gas Status Effects.

Update 27.3 (2020-03-24)

• 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 (2020-03-05)

• 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.

Update 11.0 (2013-11-20)

• Introduced.
