Avarice Band with Boon of the Hoarder instantly picks up progress orbs from elites, increasing the speed of the build significantly. The other ring is optional, but Stone of Jordan with Physical%, CDR, and Elite% will be the highest consistent damage, with Justice Lantern and Unity as decent toughness options. Nemesis bracers are strongly recommended to generate more elites, letting you proc In-Geom, letting you use Iron Skin more often to empower your thorns for faster elite kills.
If you don't yet have the Norvald's set and are using a weapon like Swiftmount or In-Geom in hand the Fervor Passive serves as a nice replacement for Heavenly Strength. If using the Lidless Wall the priority roll is Physical%, and the Vo'Toyias Spiker would be accompanied by the Provoke skill for use on Elites.
The Finery Passive is least important and can be switched out for toughness as required, with Indestructible being a good increase in farming speed if it ends up preventing deaths. Hexing Pants in the Cube are optional and can be switched out to Goldwrap or Aquila Cuirass for toughness, Warzechian Armguards for speed, Leoric's Crown to more easily meet the 56%CDR target for permanent Akarat's Champion, Illusory Boots to get through Walls from Elites, etc. Similarly the Vigilante Belt is recommended as a nice source of CDR, but entirely optional to running the build smoothly. Using Goldwrap will grant basically infinite toughness and you would probably not use any other damage negating gear or skills. If using the Belt of the Trove make sure to have Bombardment - Barrel of Spikes on your bar. The rest of the skills can be occupied by your favorite Law or other buff skills like Shield Glare - Divine Verdict, but ultimately this should make little difference to your farm speed.
The main damage source is the Boyarsky's Chip, along with a Topaz in your weapon, and your Thorns + Strength. A well leveled Bane of the Trapped will be the highest damage after this, but can be replaced by a Bane of the Powerful early in the season for an earlier power spike, Gogok of Swiftness for hitting your CDR target earlier, Wreath of Lightning for higher move speed, or Esoteric Alteration for toughness.
When rifting keep in mind that all rewards scale negatively against mob health as you increase difficulty, meaning the goal is to kill things extremely quickly unless you are making up for slow move speed. This is not a slow build, and you should play on whatever difficulty lets you insta-kill Elites with your Steed Charge when Akarat's Champion and Iron Skin is up. Give slight favor to T6/8/10 over T7/9 for better reward scaling.
