How to Unlock Every Inventor Skill in Octopath Traveler 2

Octopath Traveler 2 is an expansive RPG with several Jobs to equip and skills to choose from and upgrade. One of the most impressive and unique skill sets comes from the Secret Job Inventor, which allows you to create new and powerful items to help you in battle. Having these abilities in your arsenal will give you an edge during combat and make it easier to defeat tough opponents.

The Inventor skills are relatively easy to unlock if you know where to look. However, they have a unique unlock requirement: instead of using Job Points (JP), you must find certain items around the world of Solistia. In this guide, we’ll show you how to get your hands on every Inventor skill available in Octopath Traveler 2.

How to Unlock Inventor Skills in Octopath Traveler 2

Octopath Inventor


In Octopath Traveler 2, players can unlock Inventor skills by finding specific items throughout Solistia and presenting them to Arkar. Arkar is located in the Inventor’s Guild on the outskirts of New Delsta City. No additional action is required to use the Changeable Catapult and Springy Boots skills, as your character begins with these two skills already unlocked.
