Build Guide
Classic Gyrfalcon's Foote + Jekangbord build I've been using from T2-T5. Extremely efficient if there's 3 or more enemies.Important rolls are CDR, Holy damage, +Blessed Shield damage, Area Damage. Perma AC (Akkarat's Champion) can be maintained pretty easily with full Of Akkhan's Set.
Make sure to get a Jekangbord with 6 rolls. The build is also playable without Gyrfalcon's Foote, until you have the foote which seems to be more rare than Jekangbord (had 4 jekang's before I had my 1st and only foote) you can easily play it with a resource generator, my choice was Justice - Crack.
Resist all would be my guess.
