This is NOT a leaguestarter due to uniques needed, I would go a classic CHIEFTAIN if you leaguestart with it due to things being much easier and cheaper if you do so.

I think this build has some interesting synergies. Vulconus in main hand and Nycta's Lantern for Battlemage in the offhand makes for a good combo, when you take Avatar of Fire on the tree as well as bleed the enemy somehow. In this build, I bleed the enemy by using a Reaper, which has 50% chance to bleed innately. Defensively, this build goes the new Jugg node alongside the Rakiata Lethal Pride, which has good synergy due to math reasons I won't get into in this thread. I also go Energized Armor in the templar jewel socket along with the agnostic and the 20% more armor effectiveness mastery while not at low energy shield (we're at no energy shield so this always applies), which applies to the elemental armor conversion from the new jugg node according to POB.

Damage is pretty low but I imagine it could be a pretty good mapping character due to herald of fire and being slow/stun/chill/freeze immune.

EDIT: I took undeniable in the POB for some reason. Don't do that.
