- Armor only reduces damage taken to health, and not damage taken to shields.
- Therefore, this mod is most effective on the Carrier Prime due it having the most health and armor.
- Can also be equipped on Kubrows, Kavats and MOAs, but is mutually exclusive with Link Armor
- Metal Fiber is more effective than Link Armor if the selected Warframe has less armor than the companion's own base armor.
- Before Update 11 Sentinels didn't have armor which rendered this mod useless.
