Malestan has a good explanation of the build here. I ran something similar and it was really good but my gear wasn’t great for it to move past MoF 15 so I changed to better suit my gear. I’ve thought about changing back though since I have another 15 levels since then and probably better gear.
Edit* gear wise I ran something quite different to max my defenses and didnt use the uniques. I only use Orian’s eye now for my current build and it would likely be similar for this build. You can simply craft better stuff than set and uniques in most instances.
