After hours gathering currency and looking at pob, this version is probably the most polished. Single target and uber boss fights are still meh, but its mapping is a beast. Pob: https://pobb.in/e67D9cXh8lUT

Q/A:

1. Budget? The budget in the clip is around Mageblood + 150 Divines. You can start with minimum 70-80 divines, either rare belt or soulthrist variant. HH is great on this. Core items for a start are voidforge, stranglegasp, replica farrul fur, ralakesh.
2. How do we sustain endu charges? Endu on stun, replica farrur ful and the chance to get maximum endu on precursor emblem, also the chance to get endu on kill on tree helps a lot. Enduring composure would be also nice.
3. How much is the AoE? 6.9 meter is what i find most balance which you can see in the clip. For more meme you can do pulverize + get the aoe/endu near charge wheel in the middle + more endu somewhere (max frenzy ring). 8 meter is doable.
4. Why phase run? 50% uptime if you have increase duration support and 9 frenzy charges without anything consuming it. More phys damage.
5. Whats next to upgrade? Progenesis, maximum frenzy ring, double corruption on both chest and sword. Rare amulet/carnage heart/yoke with 4 anoints. Defiance of destiny is good if you want to be more tanky, it pretty much negates all the juiced content in the game.
6. What are some of the problems with the build that you still cant fully fix? Endu sustain on single target still feels bad. Maybe dropping immortal call, push more armour and go molten shell would be better.

Edit: items going up in price so the budget showcased in this video might be close to 250 Divines + mageblood.
