For the aura mod, see Corrosive Projection.

Combined from Toxin DamageDmgToxinSmall64.png Toxin and Electricity DamageDmgElectricitySmall64.png Electricity damage. Most effective against Ferrite armor. Corrosive status temporarily removes up to 80% of the target's armor value.

—In-game Description

Corrosive DamageDmgCorrosiveSmall64.png Corrosive Damage is one of the six secondary elemental damage types, composed of Toxin DamageDmgToxinSmall64.png Toxin and Electricity DamageDmgElectricitySmall64.png Electricity damage. It is immensely useful against IconGrineerB.svg Grineer Ferrite Armor and Fossilized Infestation b.svg Infested creatures, but fares poorly against the Proto Shields of some elite IconCorpusB.svg Corpus enemies.

Status Effects[]


The status effect of Corrosive DamageDmgCorrosiveSmall64.png 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 DamageDmgCorrosiveSmall64.png Corrosive proc will be covered in a faint green, electricity-like substance. Enemies killed by a Corrosive DamageDmgCorrosiveSmall64.png Corrosive proc will have their corpses partially corroded and dissolved.

Corrosive DamageDmgCorrosiveSmall64.png 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 ProjectionMod TT 20px.png Corrosive Projections, an active Heat DamageDmgHeatSmall64.png Heat proc, and max stacked Corrosive DamageDmgCorrosiveSmall64.png 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 ProjectionMod TT 20px.png 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 DamageDmgHeatSmall64.png Heat proc, and max stacked Corrosive DamageDmgCorrosiveSmall64.png Corrosive proc without Corrosive ProjectionMod TT 20px.png 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 ImpactMod TT 20px.png Shattering Impact, Sharpened ClawsMod TT 20px.png Sharpened Claws or a dagger in tandem with Amalgam Argonak Metal AugerMod TT 20px.png Amalgam Argonak Metal Auger.


Corrosive DamageDmgCorrosiveSmall64.png 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 DamageDmgCorrosiveSmall64.png 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 DamageDmgCorrosiveSmall64.png Corrosive damage is only reduced by 25% of a target's whole Ferrite Armor and the base damage is increased by +75%.

  • Corrosive DamageDmgCorrosiveSmall64.png Corrosive damage can be combined with Viral DamageDmgViralSmall64.png 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 DamageDmgCorrosiveSmall64.png Corrosive pairs well with weapons that do primarily Impact DamageDmgImpactSmall64.png 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 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.
