Armour Breaker Warbringer
Build Overview
The Warbringer is a jack of all trades Warrior ascendancy, but we're choosing to focus on Armour Break offensively, and Block defensively. We'll be taking Anvil's Weight and Imploding Impacts from the first two ascensions while levelling with a two-handed mace. Later into progression we'll be using Giant's Blood once we have enough strength, with a two-handed mace in the main hand and shield in the offhand - after this keystone is allocated, we'll begin to prioritize scaling block chance with Renly's Training, Turtle Charm and Glancing Blows.
Levelling
Early progression guide below, prior to unlocking Stampede and Ancestral Warrior Totem.
In the early stages of progression we're using Earthquake and Shockwave Totem as our main ability combo alongside Mace Strike.
Earthquake creates Jagged Ground which erupts for a larger hit after a duration. Shockwave Totem's slam will cause any Jagged Ground in its radius to explode, so you can force Earthquake's aftershock to erupt sooner.
Mace Strike is a free-to-use default attack option that deals respectable single target damage in the early game - make use of it when possible in close range to a boss.
Prioritize two-handed maces for weapon upgrades and passive tree nodes. See passive tree section below.

Passive Tree
Path through Brutal and Smash and move toward the Singular Purpose wheel early on. Go back for Relentless for recovery, then continue pathing to Resolute Technique. Take Beef and path to Hale Heart for more recovery, grabbing Spike Pit on the way. After your first ascension into Anvil's Weight you can begin to fill out the armour break nodes.
I plan to test Blood Magic if mana costs are an issue - will update results.
How it Works
Stampede moves the character forward, creating patches of Jagged Ground which are exploded when the final slam portion of the ability is executed. Ancestral Warrior Totem (with Jagged Ground) will create two patches of Jagged Ground per use of Rolling Slam that will also be exploded by Stampede.
Use Leap Slam to reposition and benefit from the Holy Descent recovery.
Hammer of the Gods is your finisher for tankier targets - use it when the boss is at or below 35% hp to benefit from Execute.
Note: If you don't have enough spirit to maintain Scavenged Plating and Attrition, use Scavenged Plating during general gameplay and deactivate it to activate Attrition for bossing.
