GrimTools: Paladin, Level 100 (GD 1.1.9.4) - Grim Dawn Build Calculator
Edit: Link updated for 20% chance of cooldown reduction and devotion reassignment as per recommendations made by @tqFan.
Bron Voidhurler is what you get when you combine the Voidsoul’s Aegis of Menhir benefits with the Conduit of Divine Whispers (Aegis of Menhir modifiers). The result is a build that deals very heavy hitting Aegis of Menhir’s attacks fairly often. 
Aegis can be thrown once every 0.5 seconds (with a 15% chance of cooldown reduction; I might up this later). It has a Total Damage Modifier of 65%, 66.6% of the phys damage converted to chaos, plus bonus chaos flat damage, and deals 430% weapon damage. While it does not stun targets, it does still taunt them, making this build somewhat of an aggro thief in multiplayer. Aegis has 6% attack damage converted to health, not including the 9% of global lifesteal.
Focuses on OA (3722), DA shred (254) combined with 112% crit damage (total) with Aegis makes for large attacks, 800k being the highest I’ve seen so far, but more commonly around 200-430k damage.
Because it can hit up to six targets per cast, and because there’s a chance to instantly cast it a second time, there is the potential for great AOE damage, and great self healing. The build has 124% chaos resistance reduction.
The important part about the weapon is that it has the Of The Abyss suffix, to give every attack resistance and reduced damage to targets. As this weapon is not typically a chaos damage weapon, farming it may take some time.
Inquisitor Seal plus Ascension help to boost your survivability significantly due to damage absorption.

Damage is fun, survivability is stable, even against multiple bosses in the boss room.
This is the first iteration of the build - I came up with the concept and ran with it, and have spent zero time optimising it. Suggestions welcome. 
Enjoy!
