Hi everyone,
I'm using this build with some variations:
1. Legend Gems: Esoteric Alteration (Instead of Gogok)
2. 2nd Ring: Ring of Royal Grandeur
3. Kanai Armor: Leoric's Crown
4. Body: Aquila Cuirass
5. Belt: String of Ears
This build make 100%-uptime of Akarat's Champion easier to achieve (Flawless Royal Diamond in Helm x 2 = 25%), your hero tougher (with non-physical damage reduction from Esoteric rather than Dodge Change from Gogok), and equal to Unity with Aquila Cuirass (you can choose better ring for your follower).
I can push to GR85 Solo with 100
