Just wanted to share my slightly unusual HotA build for The Thrill (season 5 conquest requiring solo GR45 with no set items).
By putting Blade of the Tribes into Kanai's Cube, you get two serious damage dealers that also buff and add Fury -- and have short cooldowns.
This build depends a lot on critical hits, including putting an Emerald into The Gavel of Judgment. I had about 30% chance and +250% damage.
The play style that worked for me began each grift with charging to full Fury (shouts and FC) and activating Battle Cry. After that, I used Furious Charge to make distance until I found a big mob of normals or some elites. Wrath of the Berserker, then War Cry and Threatening Shout to rain down damage. Then Hammer of the Ancients to deal most of the damage. If you're hitting too many monsters and your Fury starts to drop, charge it back up and thin the herd with Furious Charge. Once Wrath of the Berserker runs out, reduce the frequency of WC and TS, so WotB has a chance to get the cool down boost from Obsidian Ring of the Zodiac (cubed). This is especially important for the Rift Guardian.
I found that FC ran out occasionally, and sometimes my Fury did too. At these times, the Illusory Boots were brilliant for getting me moving towards the next mob or elite while I waited. They seem to also ignore Wallers.
I found this build to work better for me than The Furnace in KC and Avalanche as my area damage (and better than a non-elemental Seismic Slam build). But to be fair, I did have 8 Ancient items, including my weapon. And I'm annoyed I had to burn a Ramaldni's Cube.
I did GR45 on my first try with 1:35 to spare. I expect I could have reached GR47. The game rated my power as: 939k damage, 34.9m toughness, 1.4m recovery. Without the Emerald, damage was only 720k, and I was struggling at GR43.
Hope this helps someone.
