Octopath Traveler II: Armsmaster Job Unlock & Rusty Weapon Locations

The Armsmaster in Octopath Traveler II is one of the hidden jobs found in the western continent. As a hidden job, this is undoubtedly one of the most powerful classes in the game - and so you'll want to unlock it and all of its skills as early as you can, which this guide will help you with.

The gimmick of the Armsmaster is a neat one: they can equip every single type of weapon in the game. Daggers, Swords, Axes, Polearms, Bows, and Staves - they can do it all. There's a catch, however - once unlocked you must restore old rusty weapons to their former glory - which in turn allows you to equip them and use unique abilities for this class. This guide explains both how to unlock the Armsmaster, and all of the Rusty Weapon locations to get all of the skills.

Octopath Traveler 2 Armsmaster Job Unlock & Skills guide

To begin unlocking the Armsmaster job class in Octopath Traveler 2, you will need to get travel to the town of Gravell. This is the town located in the northeast side of the Wildlands. You will find a debt collector blocking your way to one of the houses in the main road. Knock him out with a Path Action so that you can get inside the house.

You'll need to take out this pesky Debt Collector with a path action to get inside the building.

Inside the house, you will find a retired blacksmith. The blacksmith will mention about wanting to work on divine weapons. Thus, begins the 'In Search of the Divine Weapons' side story quest chain to unlock the Armsmaster job class.

To complete this quest, you will need to find six rusty weapons and then have the blacksmith repair them. When the weapon is fully repaired, they become divine weapons. When you first restore a single divine weapon, you will get the Armsmaster Job License. Restoring further weapons is still worthwhile because of how powerful the Divine Weapons are. 

Here's the location of Gravell, just in case you're struggling to find the town where the Armsmaster is unlocked.

When using the Armsmaster, equipping the divine weapon will also determine which ability you can use in battle.
