It is very easy to unlock the Arsenal system for Barbarians in Diablo 4. You simply need to level up your character to level 5. At this point, the Arsenal system will be unlocked, and you can start leveling it up.

How To Level Diablo 4 Barbarian Arsenal System

It is a very simple process to level up your Arsenal system to gain more weapon expertise, a Rank 10 bonus, and some great stats. 

The only thing you need to do is play Diablo 4. Throughout your leveling process, you will pick up new, better weapons. When you hit a monster with a weapon, that weapon type, for example, a 2-handed axe, will gain Arsenal XP automatically. It is relatively easy and painless to get all weapon types to Rank 10 while going through Diablo 4's huge campaign for the first time.

Our only note here is that currently, weapons do not get any Arsenal XP during PvP.
