SCRIPT ERRORS!!
But don't worry, the admin and editor team are aware of them and they will be resolved over the next few days as our Weapons Module goes through a much needed overhaul. Sorry for any inconvenience!

Combined from Toxin and Electricity damage. Most effective against Ferrite armor. Corrosive status temporarily removes up to 80% of the target's armor value.
The status effect of Corrosive damage is Corrosion. It temporarily degrades the armor of the afflicted target by 26% for 8 seconds. Subsequent procs further reduce armor by 6% of the original armor up to 80% armor reduction in total after 10 stacks, each stack having its own duration.
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)

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:
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.
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%.
Scarab Swarm Charge to transform health into hardened scarab armor. Discharge to blast enemies with a scarab swarm; survivors have their health drained and bestowed on allies.
Energy Cost to Charge: 0
Health Drain per Armor Percent: 29 HP
Scarab Armor Cost per Cast: 25%
Inaros stands still to summon the desert sands and sacred scarabs, offering his Health as a sacrifice to gain Scarab Armor, which permanently increases his base armor by up to 100%. While holding down the ability key (default 4 ), Inaros loses 29 health points for every 1% of converted additional bonus armor, for a total of 2,900 health lost to fully charge the armor. Inaros will continue in the animation until releasing the ability key or Inaros only has 2 points of health left; health drain will cease once the bonus armor has reached 100%.
All Scarab Armor values are not affected by mods.
The armor bonus is additive to armor mods; with a fully charged Scarab Armor (100%) and a maxed rank Steel Fiber, Inaros will have a total armor value of: 225 × (1 + 100% + 110%) = 697.5
Charging Scarab Armor causes Inaros to lose all momentum, except when aim gliding.
Inaros is immune to stagger, knockback, and knockdown effects while charging Scarab Armor.
The current bonus armor value is displayed on the ability icon and also beside Inaros' health indicator.
Scarab Armor lasts indefinitely until partially or entirely removed by casting a swarm projectile, entering a Nullifier bubble, moving too close to a Comba or Scrambus, by being dispelled, or falling into a pit. Scarab Armor bonus can not be removed by enemy weapons fire.
When Scarab Armor is dispelled, all health previously converted into armor is instantly refunded to Inaros, provided his health is not at maximum value.
While Scarab Armor is at or above 25% and an enemy target is near the aiming reticle, tapping the ability key (default 4 ) causes Inaros to consume 25 energy and 25% of his total armor bonus to launch a swarm of scarabs that travels up to 20 / 22 / 25 / 30 meters away.
Scarab Swarm can not be launched if Scarab Armor value is below 25%.
Scarab Swarm is launched near the end of the casting animation, giving the player time to adjust the trajectory before the animation ends.
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.
Once launched toward the targeted enemy, Scarab Swarm infests all enemies in its path on contact. Swarmed enemies will flail in panic and receive 100 / 150 / 175 / 200Corrosive damage per second for 6 / 10 / 12 / 15 seconds, during which they are completely disabled. Each swarm host generates an aura with a 6 / 10 / 12 / 15 meter radius that converts the damage dealt by Scarab Swarm into health points for Inaros and his allies in range. Scarab Swarm can spread all of its effects to any unaffected enemies within a 5 meter radius from a swarm host for 100% of its remaining duration.
Spread radius and remaining duration percentage are not affected by mods.
Scarab Swarm cast animation of 1.25 seconds is affected by Natural Talent and Speed Drift. Charging scarab armor or launching scarab attack while stationary will prevent movement, however casting scarab attack while moving will not interrupt movement.
It is more energy efficient to cast a Scarab Swarm attack on a single enemy in the middle of a large, clustered group, and allowing the swarm spreading effect to infect all nearby enemies. This is particularly effective against Infested that naturally tend to clump together in groups.
Players can get Scarab Swarm dispelled on purpose, such as by running into a Nullifier bubble, to instantly get up to 2,900 points of health back.
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.
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.
Number of energy beams and sweep area are not affected by mods.
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 and Volt's Speed.
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, while also increasing energy drain to 40 energy per second.
Boosted damage per second is affected by Ability Strength.
Boosted beam radius is affected by Ability Range.
Boosted energy drain is affected by both Ability Efficiency and Ability Duration.
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 enemies with infested flesh.
Corrosive status effect reduces a target's current armor by 26%, with further procs removing 6% for up to 80%. Each proc has a duration and will end on its own.
Magnetic will deal 100% bonus damage to shields, dealing 25% more with every consecutive proc for up to 325% extra damage. It will also stop natural shield regeneration from shielded enemies.
Gas status effect will proc a gas damage over time effect to the target, which increases in size and damage with consecutive procs while damaging nearby enemies.
Danse Macabre consumes 20 energy per second while active and will remain active until Revenant's energy is depleted, or the ability is deactivated by pressing the ability key again.
Damage reflected by Mesmer Skin also accumulates into Danse Macabre's energy beam damage pool.
Reave has 50% reduced energy cost during Danse Macabre. Casting speed becomes instantaneous and Danse Macabre's stopping animation can be skipped if deactivated during Reave.
Revenant cannot cast Enthrall or Mesmer Skin, perform parkour Maneuvers or general interactions 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
Getting near any edge eligible for automatic edge grabs with the ability active will lock the player out of using Reave and disabling Danse Macabre, making the depletion of all energy the only way to disable channeling.
Upon energy depletion, the player will be relocated near the edge that caused the bug to initiate the queued animation.
Increasing beam damage, and subsequently energy cost, still works.
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.
Saryn infects an enemy target within 30 / 40 / 50 / 60 meters with 2 / 2 / 3 / 3 virulent spores for an unlimited duration. Each individual spore inflicts Corrosive damage per second with a 50%Corrosivestatus chance, lasting until the spores themselves or the infected enemy is destroyed.
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.
Transmitted spore and max spores per enemy via spread are not affected by mods.
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 per second alone.
When the outbreak first begins, damage per second starts at 6 / 8 / 8 / 10Corrosive damage; for every second Spores remain active, damage per second increases by 1 / 1.25 / 1.5 / 2Corrosive 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.
Initial damage and damage growth per second are affected by Ability Strength.
Damage growth enemy cap is not affected by mods.
Amount of infected enemies is unlimited, only damage growth is capped.
Current damage per second is hard-capped at 70,000 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 0.5 seconds until it reaches the initial damage amount. Damage decay stops when at least one enemy is infected by Spores.
Reset decay is inversely affected by Ability Strength (e.g., more strength reduces amount consumed.)
Damage decay rate is inversely affected by Ability Duration (e.g., more duration reduces amount of damage decay per half second.)
Nullifying effects (such as entering Sanctuary Onslaught Data-Conduits) increases the decay rate to 30% per half second.
Damage decay interval is not affected by mods.
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.
Reset decay is inversely affected by Ability Strength (e.g., more strength reduces amount consumed.)
Recast energy discount and max spores per enemy via recast are not affected by mods.
All spores destroyed via melee weapon contribute to the melee combo counter.
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.
Venom Dose is a Warframe Augment Mod for Saryn that allows Spores to be held on cast, creating a wave of energy traveling outward from the user that temporarily grants the caster and nearby allies additional Corrosive damage to all attacks.
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.
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.
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.
Media[]
An enemy affected by a corrosive proc, the green electric like visuals can be seen, although faint
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.
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.
