For the damage type, see Damage/Corrosive Damage.
Corrosive Projection is an aura mod that reduces armor for all enemies in a mission.


Rank Effect Cost *
0 -3% -2
1 -6% -3
2 -9% -4
3 -12% -5
4 -15% -6
5 -18% -7

* Aura mods increase the amount of Mod Capacity


  • This can be stacked with other teammates to reduce armor by up to 72%.
  • Has reduced effectiveness under the "Augmented Enemy Armor" Sortie condition.



  • Corrosive Projection was originally obtainable during Artifact Defense Event from special alerts, and is now available to be bought with Creds from Nightwave Offerings.
  • Prior to Damage 2.0, if all 4 players in a given cell each used a fully-ranked Corrosive Projection, this would result in negative armor values and all damage dealt by the cell would be reduced to 1. This was fixed by capping the maximum armor reduction to 100%.
  • As with Mod TT 20pxEnemy Sense, the mod card still depicts a Shield Lancer armed with a Sicarus Sicarus.


Patch History

Update 27.2
Faction Aura Changes

We are rebalancing the faction Auras to not completely bypass our rebalancing effort. More importantly though, with the complete rescale these Auras (mostly Corrosive Projection) will not be as necessary as they were.

Corrosive Projection, Shield Disruption and Infested Impedance new Rank values are:

  • Unranked: -3%
  • Rank 1: -6%
  • Rank 2: -9%
  • Rank 3: -12%
  • Rank 4: -15%
  • Rank 5: -18%

Why: We think being consistent is key. Passively removing 100% of an enemy's defenses is not an interesting choice, and we were completely inconsistent in this regard with Auras (i.e the efficacy of 4x Corrosive Projections vs 4x Shield Disruptions).

Update 25.1

  • Fixed enemies spawning being uneffected by Corrosive Projection Aura worn by players in the Rift at the time.

Update 8.0

  • Introduced as part of the Artifact Defense Event.
