Ack & Brunt

Build and guide

Build it. The Ack & Brunt offers a unique elemental absorption mechanic that significantly boosts damage. Its main weakness is a low base attack speed.

Unique trait: Elemental Absorption

Blocking elemental attacks stores a charge, adding +17.5% of the absorbed elemental damage to the next attack, stacking up to 4 times for a 70% bonus. This bonus combines additively with elemental mods. It takes an Incarnon Genesis adapter from the Steel Path Circuit, which is where most of its 2026 power comes from.

The Ack & Brunt is a unique axe and shield melee weapon, famously wielded by Tyl Regor. It stands out with its distinctive elemental absorption mechanic, allowing it to adapt and amplify its damage based on incoming elemental attacks.

Introduced in Update 17, this weapon has undergone several adjustments, including significant damage and range increases in Update 26. Its signature ability to absorb elemental damage and convert it into a damage buff makes it a versatile choice for players who can effectively utilize blocking.

While it boasts a high critical chance, its base attack speed is notably low, requiring specific modding or stance choices to mitigate this drawback. The weapon also has an Incarnon Genesis form, further enhancing its capabilities and offering new evolutionary paths.

How to get the Ack & Brunt

  1. Research the Ack & Brunt blueprint from the Chem Lab in the Clan Dojo.
  2. Complete The Duviri Paradox and Angels of the Zariman quests.
  3. Unlock The Steel Path.
  4. Earn the Ack & Brunt Incarnon Genesis from The Circuit’s Steel Path.
  5. Apply the Incarnon Genesis to the Ack & Brunt via Cavalero in the Chrysalith.

The Ack & Brunt has a high riven disposition of 1.35, making rivens a powerful option for further enhancing its stats. This disposition allows for substantial stat boosts, potentially addressing its lower base attack speed or further amplifying its critical capabilities.

Builds

Given its high critical chance and unique elemental absorption, a hybrid crit/status build is highly effective. Focus on increasing critical damage and attack speed, while also incorporating elemental mods that can synergize with its absorption mechanic. The Incarnon form further enhances its critical and damage potential.
