In reference to Stone Shape and Stone Armor:

How is the armor-bonus calculated? How does it interact (order of operations, so to speak), with Base Armor, Mods, Warframe Powers, Syndicate-Proc Buffs, Arcanes and Allied-Focus-Buffs? Is it a bonus which is additive to mods, or one which is multiplicative and applied after mods?

The reason I ask, is because although DE has yet to give us a comprehensive explanation for any of the mathematical parts of the Focus trees (the abilities themselves, not the focus farm), I already know -- through my own experimentation -- that the Naramon passive Deadly Intent is factored-into the critical hit calculations as a top-level-multiplicative, meaning that it comes into affect after mods have been calculated.

The bonuses granted by Stone Shape are small enough that the difference won't mean much (in most cases), but Stone Armor is a whopping 50% buff, so if it's treated as additive to mods, it would use calculation A.), whereas if it's treated as being multiplicative to mods, it would use calculation B.):

Let's assume I have a maxed Steel Fiber, and a maxed Armored Agility, and I'm using Valkyr.

A.) { Modified Armor Value } = { Base Armor Value * ( 1 + [mod bonus] + 0.50 ) }

{ Modified Armor Value } = { 600 * ( 1 + [ 1.1 + 0.45 ] + 0.50 ) }

{ Modified Armor Value } = { 600 * ( 1 + 2.05 ) }

{ Modified Armor Value } = { 600 * 3.05 }

{ Modified Armor Value } = 1830

B.) { Modified Armor Value } = { Base Armor Value * ( 1 + [mod bonus] ) * ( 1 + 0.50 ) }

{ Modified Armor Value } = { 600 * ( 1 + [ 1.1 + 0.45 ] ) * 1.50 }

{ Modified Armor Value } = { 600 * ( 1 + [ 1.55 ] ) * 1.50 }

{ Modified Armor Value } = { 900 * ( 2.55 ) }

{ Modified Armor Value } = 2295

The resulting final EHP modifiers are a 710% EHP modifier at 1830 armor, and an 865% EHP modifier at 2295 armor. Additionally, the increased armor would affect any and all powers cast while the buff was active, such as Frost's Snow Globe, or Atlas's Tectonics or Rumblers.
