For the aura mod, see Corrosive Projection.

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

Status EffectsEdit


The status effect of Corrosive b Corrosive damage is Corrosion. It degrades the armor of the afflicted target by 20% plus another 6% per stack. Proccing Corrosive again while another Corrosive proc is active will add a stack, capping at 10 stacks for up to 80% armor reduction in total, with each stack having their own duration of 8 seconds.

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

Armor Removal InteractionsEdit

When Corrosive b Corrosive status is combined with Heat b Heat status and Mod TT 20pxCorrosive Projection, the armor reduction is multiplicative. 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 Mod TT 20pxCorrosive Projections, an active Heat b Heat proc, and max stacked Corrosive b 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 Mod TT 20pxCorrosive 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 b Heat proc, and max stacked Corrosive b Corrosive proc without Mod TT 20pxCorrosive 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 Mod TT 20pxShattering Impact or Mod TT 20pxSharpened Claws.


Corrosive b Corrosive does not have an Empyrean counterpart and is thus not able to proc any status effect nor is it included in calculations for status proc weighting.

Type EffectivenessEdit

As with all damage types effective against armorCorrosive b 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 b Corrosive damage is only reduced by 25% of a target's whole Ferrite Armor and the base damage is increased by +75%.

  • Corrosive b Corrosive damage can be combined with Viral b 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 b Corrosive pairs well with weapons that do primarily Impact b 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 HistoryEdit

Update 27.2
  • 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.
