Barbarian Arsenal System - Class Mechanic
The Barbarian has the ability to specialize the weaponry he uses and level up weapon types for improved combat.
The Arsenal System unlocks automatically at level 5.
As the name suggests this is the Barbarian’s collection of weapons but it specifically refers to weapons he has on his loadout and not simply in his backpack.
In Diablo 4 the Barbarian can equip four weapons at one time switching between them automatically depending on which skill he is using. He can have a two-handed bludgeoning weapon, a two-handed slashing weapon, and two single-handed weapons to dual wield.
- The Arsenal System will become available at level 5 automatically.
- Via the Expertise Tab, players can see the ranks of weapons which will scale-up to level 10.
- Once rank 10 is reached, an additional bonus is applied for that weapon type that has reached rank 10.
- Players must assign a weapon to a skill via the skills menu.
It's best to think of the Arsenal System as a bonus for your weapons and it's more beneficial to select the best weapon you have.
Expertise
As the name suggests Expertise determines the Barbarian's proficiency in using different weapon types (1-handed axes, polearms etc). Proficiency levels begin at 1 for every weapon type but the more you use the weapon type the more their level increases up to level 10. Each level improves the bonuses applied when using the weapon type, level 10 providing the most powerful bonuses.
| Expertise | Rank 10 Powers | Rank 10 Additional Bonus |
|---|---|---|
| 1-Handed Axes | (5.0%) Increased Critical Strike Chance against Injured enemies. Double this amount when using two Axes. | Lucky Hit: Critical Strikes have up to a (55%) chance to grant (+0.6%) increased Attack Speed for (2) seconds. Double the Attack Speed bonus when using 2 Axes. |
| 1-Handed Maces | (x10%) increased damage to Stunned enemies. Double this amount when using 2 Maces. | Lucky Hit: Up to a (10%) chance to gain Berserking for (1.50) seconds when you hit a Stunned enemy. Double this chance when using 2 Maces. |
| 1-Handed Swords | Lucky Hit: Up to a (10%) chance to gain (5) Fury when hitting a Crowd Controlled enemy. Double this chance when using two Swords. | Killing a Crowd Controlled enemy grants (+15%) increased Attack Speed for (3) seconds. Double this amount for kills with 2 Swords. |
| Polearms | (x10%) increased Lucky Hit Chance. | You deal (+10%) increase damage whilst Healthy. |
| 2-Handed Axes | (x15%) increased damage to Vulnerable enemies. | (+10%) increased Critical Strike Chance against Vulnerable enemies. |
| 2-Handed Swords | (+20%) of Direct Damage you deal is inflicted as Bleeding damage over 5 seconds. | You deal (x30%) increased Bleeding damage for (5) seconds after killing an enemy. |
| 2-Handed Maces | Lucky Hit: Up to a (10%) chance to gain (2) Fury when hitting an enemy. Double the amount of Fury gained whilst Berserking. | You deal (x15%) increased Critical Strike Damage to Stunned and Vulnerable enemies whilst Berserking. |
Technique Slot
This option is unlockable at Level 15 when the Barbarian gets the Quest, Masters of Battle and has to speak with Forgemaster Gerti in Ked Bardu in the Dry Steppes.
The Technique slot gives you the Expertise bonus of a certain weapon type regardless of which weapon type you use if you choose it as your Technique. So if you have level 10 Expertise in 2-Handed Maces but you want that level 10 Expertise to apply to Polearms you'd select it as your Technique so now the bonuses for your Polearms would be that of a level 10 2-Handed Maces.
