CalculationsEdit

Armor ValuesEdit

Steel Fiber gives additional Armor based on the frame's Base Armor.

The Total Armor can be calculated by the following formula:

Total Armor = BaseArmor * (1 + SteelFiberPercent)

Example - 190 Base Armor with 110% Steel Fiber would be calculated as follows:

Total Armor = 190 * (1 + 1.10) = 399 Total Armor

Damage MitigationEdit

Damage Mitigation is the amount off the total damage that armor reduces, and is calculated as:

 Damage Mitigation = Total Armor / (Total Armor + 300)

The following table shows the net Damage Mitigation percentage values provided by armor for different key base armors that various frames have.

Effective HealthEdit

Higher armor values can be thought of as increasing your effective health in relation to incoming damage.  However, this would only apply to damage types that do not ignore armor.  Because "effective health" more literally translates as "the maximum amount of damage you can take", if we simply set your "Total Health" equal to your "Incoming Damage" after Damage Mitigation, and then solve for the Incoming damage alone, we can determine your Effective HP.

Total Health = Incoming Damage * Damage Mitigation %
Total Health / Damage Mitigation % = Incoming Damage

As Armor Increases, Damage Mitigation values decrease, and therefore Effective HP drastically increases. Below are two tables with examples of how Effective HP increases with armor. All values are rounded to the nearest integer.

NotesEdit

  • Armor and Steel Fiber only mitigate damage to Health.
  • This mod does not improve Shields or Rhino's Iron Skin.
    • As of Update 13, it was confirmed to be true that Iron Skin is not improved with this mod.  To test this, a player counted the number of strikes it took a Grineer Butcher to destroy all the armor points of Iron Skin, with and without Steel Fiber.
  • This mod is less effective on frames with less than 100 armor
