==Armor Removal Interactions==
===General===
*This mod stacks additively with itself when multiple teammates are using it, reducing enemy armor up to 72% with a 4-player squad.
**Armor reduction from this aura maxes out at 80%. This can be achieved by having all squad members equipping this aura with at least three squad members equipping too.
*Armor reduction stacks additively with Warframe abilities that reduce armor, such as and 
**For example, when Corrosive Projection is equipped, after a single cast of , an enemy will have armor remaining.
*The effectiveness of this mod is reduced under the "Augmented Enemy Armor" Sortie condition.
*Currently, the only non-ability method to completely remove armor is to use , or a dagger in tandem with . It should be noted that using Corrosive Projection is multiplicative with these mods and thus will not cause them to strip armor faster.

For example, a full 4-player squad with max-rank Corrosive Projections, an active proc, and max stacked proc will result in an enemy's armor being reduced to:
:.
If only one player has a max-rank Corrosive Projection with the above statuses, an enemy's armor would instead be reduced to:
:.
==Tips==
*Most effective against Grineer enemies, although useful against Infested due to armor-buffing Swarm-Mutalist MOAs.
==Trivia==
*Corrosive Projection was originally obtainable during Artifact Defense Event from special alerts, and is now available to be bought with Creds from Nightwave Offerings.
*At the time of release, Corrosive Projection decreased enemy armor by 5% each mod rank up to 30% reduction.
**Prior to Damage 2.0, if all 4 players in a squad each used a fully-ranked Corrosive Projection, this would result in negative armor values (a 120% reduction) and all damage dealt by the cell would be reduced to 1. This was fixed by capping the maximum armor reduction to 100% before reduced the armor reduction to 3% per rank.
*As with , the mod card still depicts a Shield Lancer armed with a .
