The prophecies variant of the SFA build is the Armour of Earth + Kinetic Armour build. I think there's a build on wiki somewhere, I 'll have a look later and edit my post.
Armor of Earth + Kinetic Armor will make you take very little damage, but against high level enemies, to get the constant 0s, you would have to get Stoneflesh Aura.
The graph between Armor rating and Damage done to you, is not linear. But you would need skills to increase your armor really high, so you get damage in the range of 5-20 and then use Stoneflesh or Shield of Absorbtion to reduce the rest of that damage.
