Diablo 4 Barbarian Weapon Expertise Guide

Barbarian Expertise

Expertise is the special mechanic of the Barbarian Class in Diablo 4, that allows you to level up your Weapon skills and earn additional bonuses! Expertise is tied to the Barbarian’s Arsenal system and their ability to use four weapons at the same time. Barbarians can carry a Two Handed Bludgeoning Weapon, a Two Handed Slicing Weapon and two One Handed Weapons for Dual Wielding. Certain skills require a certain type of weapon used, so it is possible for a Barbarian to use all three different types depending on their skills.

At level 15 Barbarians can also unlock a Technique Slot that gives access to a special bonus from a Weapon expertise of their choice. In order to unlock this slot however, you will have to complete a Class specific Priority quest. The Expertise System is essential to create strong Barbarian Builds in Diablo 4!

Barbarian Technique in Diablo 4

Technique is a special slot for Barbarian in Diablo 4 that unlocks an Expertise Bonus! You can pick any of your available Weapon Expertise for the Technique slot, as long as they are at least Rank 1. The Technique affects every weapon you are using, even if it is a different type of the chosen Expertise. So the Two-Handed Weapon Mace Expertise will give you a chance to gain Fury when hitting an enemy even if you are using a Polearm. If you are using the same weapon though, the effect will not stack and double itself.

To unlock the Technique Slot you need to complete a Barbarian specific Priority Quest first. The Quest is called “Barbarian: Masters of Battle” and you will get it automatically when you reach level 15. To start the quest you will have to travel to Ked Bardu in the Dry Steppes zone and talk to the Forgemaster Gerti. The Quest is rather easy, since all you have to do is complete a few basic tasks around the zone. Follow the instructions and return to Gerti to complete the Quest and unlock your Technique slot!
