Corrosive Damage

Corrosive Damage
Icon

For the aura mod, see Corrosive Projection.

Created by combining  Toxin and  Electricity damage. Highly effective against Grineer Ferrite Armor and Fossilized Infested.
Corrosive Status Effect temporarily removes up to 80% of the target's armor value with multiple stacks.

—In-game Description

 Corrosive Damage is one of the six secondary elemental damage types, composed of  Toxin and  Electricity damage. It is immensely useful against  Grineer Ferrite Armor and Fossilized  Infested creatures, but fares poorly against the Proto Shields of some elite  Corpus enemies.

Status Effects

General

The status effect of  Corrosive damage is Corrosion. It temporarily degrades the armor of the afflicted target by 20% for 8 seconds. Each stack inflicted reduces the original armor by an additional 6%, culminating in a total armor reduction of 80% at 10 stacks, with each stack having its own duration. Any stacks applied after the 10th will replace the oldest stack.

 Emerald Archon Shard can increase the maximum  Corrosive status procs by +2 (+3 for  Tauforged). Applying 14 stacks can fully remove all armor for the duration of the status.

 Hydroid's passive causes enemies damaged by him to be permanently more vulnerable to  Corrosive status, with the first proc degrading 50% of armor, allowing him to have 100% armor reduction at 10 stacks. This vulnerability can come from any source of  Corrosive procs, not just from Hydroid's weapons or abilities, as long as he has damaged the enemy.

Enemies affected by a  Corrosive proc will be covered in a faint green, electricity-like substance. Enemies killed while affected by a  Corrosive proc will have their corpses partially corroded and dissolved.

 Corrosive status armor reduction is multiplicative with other armor reduction sources. This can be expressed as the following:
Armor after reduction = (1 - 50%) × [1 - (20% + 6% × Number of Corrosive stacks)] × (1 - 18% × Number Corrosive Projections)

  View detailed examples  ▾▾

For example, a full 4-player squad with max-rank  Corrosive Projections, an active  Heat proc, and max stacked  Corrosive proc will result in an enemy's armor being reduced to:

(1 - 50%) × [1 - (20% + 6% × 10)] × (1 - 18% × 4) = 2.8%.

If only one player has a max-rank  Corrosive Projection with the above statuses, an enemy's armor would instead be reduced to:

(1 - 50%) × [1 - (20% + 6% × 10)] × (1 - 18%) = 8.2%.

An active  Heat proc, and max stacked  Corrosive proc without  Corrosive Projection would result in an enemy's armor being reduced to:

(1 - 50%) × [1 - (20% + 6% × 10)] = 10%.

Currently, the only non-ability method to completely remove armor is to use  Shattering Impact,  Sharpened Claws or a dagger in tandem with  Amalgam Argonak Metal Auger.

Railjack

 Corrosive 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.

Type Effectiveness

Grineer Health	Corrosive Modifier	Corpus Health	Corrosive Modifier	Infested Health	Corrosive Modifier	The Murmur Health	Corrosive Modifier
Cloned Flesh	—	Flesh	—	Infested	—	Indifferent Facade	—
Ferrite Armor	—	Shield	—	Infested Flesh	—	Machinery	—
Alloy Armor	—	Proto Shield	—	Fossilized	—	Ferrite Armor	—
Machinery	—	Robotic	—	Infested Sinew	—

As with all damage types effective against armor,  Corrosive damage's type modifier works in two ways: it ignores a percentage of the target's armor, and increases the damage dealt in the same way as a type modifier against hitpoints. Practically speaking, this means that  Corrosive damage is only reduced by 25% of a target's whole Ferrite Armor and the base damage is increased by +75%.

• Tips & Tricks

Info

• Hydroid expends 25 energy to mark a targeted location for orbital bombardment over unrestricted range, calling forth an artillery barrage-like salvo of water missiles from above to strike the marked area 3 / 5 / 8 / 10 meters in radius for 4 / 6 / 8 / 10 seconds. Water missiles launch from above in a salvo of 4 per second, with each missile exploding on impact dealing 150 / 175 / 225 / 300  Corrosive damage with a 100% status chance and  Stagger to enemies within a 5 meters explosion radius.
  • Damage does not bypass obstacles in the environment and does not diminish with distance.
  • The barrage will be centered on the spot where the reticle is pointing up to the first solid object within view. This allows Tempest Barrage to be cast at distant locations as long as one has line of sight. Note that it tends to fall short if cast through a door or gateway.
  • When cast on  Snow Globe it will not be able to strike through it, but when cast within it will fall through it normally.
• Ability Synergy:
  • Hydroid's Passive allows the first  Corrosive stack to remove 50% armor and is able to fully remove all armor at 10 stacks.
• Tempest Barrage is a One-Handed Action that allows casting during movement, while midair, and on ziplines.
• Can be recast while active to create multiple barrage instances.
• Water missiles and their impact indicator circles are affected by Hydroid's chosen Warframe energy color.
• Breaks containers and damages turrets/cameras.
• Subsuming Hydroid to the Helminth will offer Tempest Barrage and its augments to be used by other Warframes.

Info

• Hydroid expends 50 energy to cleanse himself of all negative Status Effects while transforming into liquid and surging forward as a wave of water. While traveling in waveform, Hydroid becomes completely Invulnerable to damage, as his speed increases to ? / ? / ? / 40 meters per second over a duration of 1 second; the wave may be steered during its travel by changing the view direction, and Hydroid may halt his surge early by jumping (default Spacebar ). Enemies within 3 / 4 / 5 / 6 meters of the wave are  Ragdolled and pulled along by the riptide, while dealt 100 / 200 / 250 / 300  Corrosive damage when caught by the wave and when the wave breaks at the end of the duration, and are inflicted with a variable number of  Corrosive Status Effects based on how long they are carried by the wave.
  • Tidal Surge's pull on enemies attempts to collect them in front of Hydroid's wave. At the end of the surge, pulled enemies are left clumped together at the location where the wave ended.
  • Hydroid jumping out of Tidal Surge will carry forth its momentum as he travels through the air.
• Can be recast while active to remain in waveform and renew the surge for continuous travel toward a new direction. Tidal Surge's energy cost is discounted by 50% if cast again while Hydroid is surging.
• Ability Synergy:
  • Hydroid's Passive allows the first  Corrosive stack to remove 50% armor and is able to fully remove all armor at 10 stacks.

Tips & Tricks

• It can be used to reach or pass certain areas of the map.

Bugs

• Sometimes when Hydroid emerges from the wave, his "fin" will be gone.
• On PS4, if Hydroid is in the middle of a Tidal Surge when all players reach the extraction point, he will be permanently stuck in his dashing pose and simply clip into the drop ship during the "Mission Complete" mini-scene that plays during the loot screen.

	3 75	Plunder Plunder Armor from nearby enemies and increase Corrosive Damage on your Abilities and weapons. Enemies affected by Corrosion Status offer a greater increase. Introduced in Update 34.0 (2023-10-18)	Strength:20 / 25 / 30 / 40 (armor per enemy) 20 / 25 / 30 / 40 (armor per  Corrosive status) 750 (armor cap) 5% / 6% / 7.5% / 10% ( Corrosive bonus damage per enemy) 5% / 6% / 7.5% / 10% ( Corrosive bonus damage per enemy per  Corrosive status) 200% ( Corrosive bonus damage cap)

• Info
• Augment

Info

• Hydroid expends 75 energy to siphon the armor from all on-screen enemies within 25 meters,  Staggering them and consuming any active  Corrosive status to permanently remove their armor. For 10 / 15 / 20 / 25 seconds, Hydroid gains a 20 / 25 / 30 / 40 bonus armor per enemy and per consumed  Corrosive status effect to a cap of 750 bonus armor, and a  Corrosive damage bonus to all abilities and weapons by 5% / 6% / 7.5% / 10% per enemy and per consumed  Corrosive status effect to a cap of 200%  Corrosive damage bonus.
  • Does not require Line of Sight from Hydroid; enemies only need to be within view of the camera to be affected.
    • An enemy that has line of sight but is off-screen will not be hit.
  • While the bonus is active, a stylized armor and damage bonus counter appears above the ability icons.
  • If Plunder affects enemies on recast, the bonus values are replaced by the new values. If no enemies are affected, the bonus values will not change but the duration will not be refreshed.
  • Damage increase does not apply to Helminth infused abilities.
• Ability Synergy:
  • Passive allows 10  Corrosive stacks to fully and permanently remove all enemy armor.
  •  Tempest Barrage,  Tidal Surge, and  Tentacle Swarm all inflict  Corrosive status for Plunder to apply its effects.

Info

• Hydroid expends 50 energy to summon a creature from the deep, causing up to 8 / 12 / 16 / 20 tentacles to emerge from all surfaces within a marked location 15 / 15 / 15 / 15 meters in radius, cast over unrestricted range. Tentacles prioritize spawning beneath enemies inside the radius, with each tentacle capturing their initial targets and lifting them into the air until the ability expires after 10 / 13 / 18 / 20 seconds. Captured enemies are incapacitated in a  Ragdoll state and stay attached to the tentacles while suffering 50 / 100 / 150 / 200  Corrosive Damage with 100% status chance per second.
  • Against enemies with crowd control immunity and protected by Overguard, tentacles will not capture targets or inflict their  Corrosive damage over time, since they are not physically attached. However, Overguarded enemies will be attacked once by the tentacle spawning under them, inflicting 50 / 100 / 150 / 200  True damage with a guaranteed  Corrosive status effect.
  • Tentacles detect and capture new enemy targets when they come into range.
  • Each tentacle can only capture one enemy at once.
    • This means that Tentacle Swarm can only incapacitate 20 enemies at any given time.
  • Tentacles with captured enemies will hold their victims steady in the air, allowing players to take aim and kill their targets.
• Ability Synergy:
  • Hydroid's Passive allows the first  Corrosive stack to remove 50% armor and is able to fully remove all armor at 10 stacks.
    • However, Tentacle Swarm alone cannot reach 10  Corrosive stacks and is only able to reach 8 stacks at most due to inflicting status per second and the status's 8 second duration.
• Casting Tentacle Swarm is a two-handed action that stops Hydroid's movement and other actions.
• Can be recast while active; however, only one instance of Tentacle Swarm can be active at a time. Recasting will replace the previous instance.
• Hydroid briefly summons the Kraken at the center of the spawn area as a visual effect. The Kraken emerges from a pool of water, then submerges slowly and disappears. Kraken is affected by Hydroid's chosen Warframe appearance and energy colors.
• Tentacles appear as translucent water tendrils emerging from a small puddle of water. Tentacles emit splashes of water periodically, as well as a steam particle effect at their base which is affected by Hydroid's chosen Warframe energy color. However, when the ability is cast by  Hydroid Prime, the tentacles will be opaque and more organic in appearance.

	4 100	Scarab Swarm Summon a Scarab Swarm to attack enemies with guaranteed Corrosion Status. Damage scales with Inaros' Health. Enemies killed while immersed in the swarm summon a Swarm Kavat that fights alongside Inaros and guides the scarabs to other enemies. Introduced in Update 18.5 (2016-03-04)	Strength:N/A

Info

• Inaros expends 100 energy to hurl swarms of scarabs that travel up to 20 / 22 / 25 / 30 meters away, infesting all enemies in their path. Swarmed enemies will flail in panic and receive 5% / 6.5% / 8% / 10% of Inaros' max Health as  Corrosive damage with a guaranteed status effect per half second for 6 / 10 / 12 / 15 seconds, during which they are completely disabled. While active, Scarab Swarm splits a flying swarm every ? seconds to spread to an unaffected enemy within a 12 meter radius from a swarm host for its remaining duration.
  • Launching a Scarab Swarm on an enemy that is still under the effects of another Scarab Swarm, will not refresh the debuff.
  • Scarab Swarm's projectile possesses innate punch through but does not bypass obstacles in the environment.
• When an enemy affected by Scarab Swarm dies, they spawn a friendly Swarm Kavat that scratches enemies to spread Scarab Swarm. A maximum of 3 Swarm Kavats can spawn, each lasting 20 seconds.
  • Number of active Swarm Kavats are tracked as a buff icon beside Inaros' hitpoints indicator.
  • Swarm Kavat-inflicted Scarab Swarm does not spread flying swarms.
• Ability Synergy:
  • Swarm Kavat claw swipes contribute as hits toward Inaros' revival via his Passive.
  •  Desiccation's Curse allows Finisher kills to summon a Swarm Kavat and increases the maximum limit of Swarm Kavats to 5.

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.

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

Only applies  Corrosive damage on armored enemies.

	1 25	Spores Inflict a target with a pox of Corrosive spores. Spread spores to nearby enemies by destroying them or killing their host. The longer the Spore spreads, its damage will increase.

• Tips & Tricks

Info

• Saryn expends 25 energy to infects an enemy target within 30 / 40 / 50 / 60 meters with 2 / 2 / 3 / 3 virulent spores for an infinite duration. Each individual spore inflicts  Corrosive damage per second with a 50%  Corrosive Status Chance, lasting until the spores themselves or the infected enemy is destroyed.
• Saryn's disease spreads its infection rapidly, grows evermore lethal, and decays in the absence of hosts over the course of the epidemic:

• Spread
• Growth
• Decay

• Shooting or hitting a spore directly bursts its membrane to release infectious pus, which regrows the spore on its host and transmits 1 spore to all nearby enemies within 10 / 12 / 14 / 16 meters; infected enemies can carry up to 3 spores via transmission from another enemy.
  • Spores can spread by directly bursting them with weapons, abilities, and Bullet Jump. Enemy attacks can also burst spores on contact.
  • Spread bypasses obstacles in the environment and damage does not diminish with distance.
• All spores on an infected enemy will burst and spread if any of the following conditions are met:
  • Spores' initial target is killed by any source.
  • Players landing the killing blow on any infected enemies.
  • Infected enemies are killed by  Molt's explosion damage.
  • Saryn's weapons hitting anywhere on the infected enemies' body while  Toxic Lash is active.
  • Infected enemies are killed by any source while sickened by  Miasma.
• Spores do not spread if enemies infected via transmission are killed by Spores' damage over time.

When the outbreak first begins, damage per second starts at 6 / 8 / 8 / 10  Corrosive damage; for every second Spores remain active, damage per second increases by 1 / 1.25 / 1.5 / 2  Corrosive damage per infected enemy, up to a damage growth cap of 7 infected enemies. Current damage per second is uniform across all active spores and will apply to newly infected enemies.

• Current damage per second is hard-capped at 100,000 damage.

While Spores is active, a stylized infection meter appears above Saryn's ability icons on the HUD, indicating the current damage per second and tracks the number of infected enemies in the mission affected by spores belonging to the player.

When zero infected enemies remain, Spores' current damage per second is instantly reduced by 20% then decays at 10% of the new total every half second until it reaches the initial damage amount. Damage decay stops when at least one enemy is infected by Spores.

• Nullifying effects (such as entering Sanctuary Onslaught Data-Conduits) increases the decay rate to 30% per half second.
• Reset decay is inversely affected by  Ability Strength, meaning more Strength reduces the amount consumed.
• Damage decay rate is inversely affected by  Ability Duration, meaning more Duration reduces the amount of damage decay per half second.

Current damage per second is visibly subtracted from the meter whilst a red flashing "decaying" warning message replaces the counter for number of infected enemies.

The infection meter disappears when it reaches the initial damage amount.

---

• If Spores is still active, recasting Spores on any enemy consumes 20% of current damage per second from the infection meter and casts Spores for 50% reduced energy cost. Recasting on an infected enemy grows a new set of spores on the target, which carries up to 12 spores via recasting Spores on it.
  • Recast decay is inversely affected by  Ability Strength, meaning more Strength reduces the amount consumed.
• All spores destroyed via melee weapon contribute to the melee combo counter.
• Spore Snapshotting
  • The first Spore casted retains all of your regular Strength and conditional Strength as well as Range (like from the Fissure buff).
  • If your Spores begin to decay and there are none in the game, as long as the unique Spore icon at the bottom right does not disappear, Saryn will maintain all conditional stats from when she initially casted it. Even if they have expired.
  • Casting new Spores while the Spore icon is still present will cause the new Spore to still retain the original conditional stats even if the new Spore has higher values.
  • If you want to properly cast Spores with new stats ( Ability Strength &  Ability Range), you must let the Spore icon disappear.
• Ability Synergy:
  •  Toxic Lash can make spores burst with every attack, even without direct hits.
    • Hitting a spore while Toxic Lash is active applies an additional  Toxin proc.
  •  Miasma deals 400% damage to enemies affected by Spores.
• Spores is a one-handed action. As such, it can be used while performing various maneuvers and actions without interruption.
• If the initial target dies before the spores appear, energy used for Spores will be refunded.

Tips & Tricks

• Cast on an enemy in the middle of a crowd and promptly kill it or use one of the many methods to spread the spores.
• Each spore inflicts damage per second and  Corrosive status effect on proc, which is tripled on an enemy carrying three spores from a max rank Spores cast or accumulated from transmission from other infected enemies.
• Infect at least 7 enemies to maximize damage growth, allowing Spores to reach higher damage per second counts over time.
• Mod for Ability Strength to increase initial damage, damage growth per enemy, status chance, while reducing the reset decay on recast or on zero infected present.
  • Status chance can reach 100% with 200% Ability Strength.
• Recast Spores several times to inflict an enemy with up to 12 spores to strip its Armor quickly, deal more damage per second instances, and provide more spores to spread.
  • However, note that each recast will consume a percentage of damage per second stored in your infection meter.
• Using melee to hit enemies makes it easier to burst spores, compared to firearms, especially with Range mods, e.g.  Reach ( Primed).
• Use  Toxic Lash to spread spores on an infected enemy on every hit using your gun or melee.
• Cast  Miasma to inflict quadruple damage to all enemies infected by Spores within range.
• Can be used to destroy Corpus cameras and (active) turrets. A spore will appear but a camera dies on the first tick.
• When combined with AoE weapons (such as  Ignis and  Embolist, which both deal DoT, increased by Saryn's passive), the spores will pop very easily, quickly spreading  Corrosive procs.
  • Thrown secondaries loaded with  Concealed Explosives are also effective and economical at quickly popping Spores, especially when combined with  Fulmination ( Primed).
• The ability synergizes well with Nova's  Molecular Prime, both spreading and weakening enemies until one dies and causes a series of chain explosions and effectively quartering enemy survivability.
• Spores is excellent for bosses with shields to prevent them from recovering.
  • This is quite effective against Ambulas since it targets the torso and, like all MOAs, he takes three times damage on that body part.
• Sentinels can also pop Spores.
  • Equipping a sentinel with the  Sweeper weapon increases this chance.
• Spores that are popped on a target's weak point, like the head, will do extra damage based on the respective damage multiplier.
  • For example, if you pop a Spore on an enemy's head, it will deal 50 damage (25 x 2 damage multiplier).
  • Spores' DoT ticks are unaffected by weak spots.
  • AoE damage from popping spores is unaffected by weak spots. Nearby enemies will still only take 25  Corrosive damage from popped spores on weak spots.
• A Range-based Spores build is good for earning Focus points in stage-less endless missions such as Survival, Disruption and Void Flood, as long as Saryn can keep it from decaying.
• Active spores can help fill the self-revive gauge from the  Unairu school's Last Gasp.

Additional Effects

Some mods add additional effects when a  Corrosive occurs or dealing  Corrosive damage.

 Emerald Archon Shard

Tips

•  Corrosive damage can be combined with  Viral damage (when applicable) to create a deadly damage combo against enemies with armor, especially the Grineer. The reduction of armor will lessen the reduction of damage, while viral procs will increase damage dealt even further.
•  Corrosive pairs well with weapons that do primarily  Impact damage. This results in an excellent faction-neutral build, as Corrosive is either buffed or normal against every damage type except for Corpus Proto Shields, which the Impact makes up for, especially on a high-crit weapon.

Patch History

Update 33.6 (2023-07-27)

• Fixed crash related to Corrosive procs.

Hotfix 33.5.3 (2023-06-23)

• Fixed crash related to Corrosive procs.

Update 31.6 (2022-06-09)

• (Undocumented) Corrosive damage icon updated to match Essential Corrosive Glyph.

Update 27.2 (2020-03-05)

• The first Corrosive Status Effect strips 26% Armor. Subsequent Corrosive Status Effects strip 6% more Armor, leading up to 80% Armor removal. Each Corrosive Status Effect lasts 8 seconds.
  • Note: Corrosive was the only Status with infinite Duration and 100% Efficacy toward a defensive stat. This was necessary to some based on how Armor Scaled. We feel our rebalancing efforts need a differently behaving Corrosive to balance out all Status overall.

Update 11.0 (2013-11-20)

• Introduced.
