Understand Corrosive Projection
Useful when…
- Apply the Aura's listed armor reduction to enemies.
- Choose it when enemy armor is the concern addressed by the Aura slot.
Effect and Aura slot
Corrosive Projection reduces enemies' armor by 3% at rank 0, 12% at rank 3, and 18% at rank 5. It is an Aura with Naramon polarity and a listed base drain of -2. The description supplies the reduction amount, not a complete armor or damage calculation.
Rank investment
Example steps cost 20 Endo and 966 Credits, then 80 Endo and 3,864 Credits, then 320 Endo and 15,456 Credits. The later ranks raise the reduction but require substantially more resources; choose a rank that fits the intended Aura capacity and benefit.
Choosing another Aura effect
Shield Disruption instead reduces enemy shield capacity by 18% at its listed maximum. Combat Discipline changes health on kills for the player and squadmates, while EMP Aura reduces Corpus enemy accuracy. They address different conditions, so they are alternatives when their specific effects better match the mission or squad plan.
Acquisition
The listed drop entries are Duviri/Endless Tier 1 and Tier 3 on Normal. These are cached entries and do not guarantee current availability.
Limitations and tradeoffs
- The Aura slot is committed to armor reduction instead of another listed Aura effect.
- Higher reduction requires more Endo and Credits and may use more capacity.
Common mistakes to avoid
- Assuming armor reduction also reduces shields.
- Treating the listed 18% reduction as a full damage increase or final armor calculation.
