Octopath Traveler 2 Inventor Job Guide: How To Unlock All Skills

The Inventor is a secret job and class in Octopath Traveler 2 that is designed to adapt to any role. Your skills no longer require any SP.

Inventor is one of the secret jobs in Octopath Traveler 2 in which you can create different inventions for both offense and support.

This secondary job is different in the sense that you don’t need Job Points needed to unlock the skill. But rather you need to gather items from all over the world to unlock skills one at a time.

After unlocking the Inventor job, you will have Sword and Axe as your equipable weapons. To get you on your feet, Octopath Traveler 2 also gives you Changeable Catapult and Springey Boots skills.

For the rest of the skills of this hidden job, you need to become an inventor and make them as you gather items. Divine skill will be unlocked once you have made a couple of inventions which will reduce the crafting time on each skill.

How to unlock the Inventor job in Octopath Traveler 2

To unlock the Octopath Traveler 2 Inventor job, you first need to have access to the Inventors Guild. Just like any other secret job, the Guild will act as your proof of license that your character can then later use to have Inventor as your Secondary Job.

To get the Inventor Guild, you need to talk to the Arkar in his house. For that, you need to make a journey toward the eastern part of New Delsta Highroad located in the Brightlands region.

After getting there, you need to find a bridge which is located in the southeast part of the region. You will find yourself in front of a house after crossing that bridge. As soon as you enter the house, you will find Arkar whom you need to talk to.

The inventor job will be unlocked after your conversation ends with the Arkar. He will then award you with Inventors Guild which you can use any time to access this secret job.

Where to find all Inventor skill items?

There are several skills that you can unlock for the Inventor in Octopath Traveler 2 by finding different items. There is no easy way out of this. You need to head to each Inventor skill item location to unlock their respective skill.

Critical Scope

To get your hands on the Critical Scope, you need to build it. For that, you need the following items:

You can find Empowering Lychee quite commonly all over the map but most certainly, you can get it from the chest located in North Beastling Traverse.

Best character for the Inventor job in Octopath 2

Agnea can be the best support character for the Octopath Traveler 2 Inventor job as she can support a lot from the Dancer skill. She can make weapons faster than any characters as she gets two turns with her Leave no Trace and Throne’s Latent Power.

With Agnea’s swift moves, she has the chance to make the first move in the fight before the enemy is even started. Being able to buff your physical attacks, she can bring the best out of the party.

Another best support character choice for the Inventor job is Mistral. Talking of defensive moves, well, he lacks quite a lot, but all the damage taken will be negated by his Heal Wounds skill.

This means that he can stay longer than any character and that longevity can be utilized to produce weapons at all times.
