The video is in Korean, but you can just watch the first few seconds where it kills Xesht difficulty 3.

Build explanation

I'm using Hateforge & Serpent's egg to generate charges. For generating rage, I'm using 3 Ngamahu charms with some charm related uniques (Pragmatism + Bijouborne). For getting fire self-damage, I use Scold's Bridle and Molten Being passive node which converts 5% of physical damage taken as fire damage.

This results in activating 3 charms per 2 seconds, which means getting 3 average endurance charges per second (i.e. 1 ancestral warrior totem per second). I thought this way can generate more charges than using warcries (raging cry + roaring cries), when there is no unique enemy nearby. But according to this comment, using a warcry with 10 power generates 16 rages instead of 8 for unknown reason (maybe due to Talisman of grold?); so maybe warcry is better. But I just went with the charm.

Mana issue can be resolved by Heart of the Well unique jewel, with "Recover #% of maximum mana when a charm is used" option.

It's fun but summoning too many totems in your presence may lag the game.
