Wanted to post my build that I finalized a couple days back, the one that used the tech of consuming endurance charges rapidly to get absurds amount of life recovery and fire damage.

Primal Hunger keystone, Rageforged in walking calamity so that each meteor consumes rage. Jagged ground 1 in ancestral cry ferocious roar so that each step consumes an endurance charge. Take all the consume endurance charge passives on the tree (30%+ life recovery per second, 100+ fire damage, 20+ damage as extra fire)

Build deals damage via fire spell on hit living bomb that triggers from both Molten crash fissures and ancestral cry steps, as well as ignites which trigger fire-infused comets. Since it's spells, we also don't care to much about losing the damage bonus from rage

*Other than mainting buffs, no buttons are required.
