Octopath Traveler II: Inventor Job & Skill Unlock location guide
The Inventor Job Class is one of the ultimate, top-secret classes available in Octopath Traveler II - and it has some complexities that mean that unlocking this job and its abilities isn't as simple as just finding it on the Eastern Continent - you'll have to actually undertake a number of steps to unlock the Inventor and its abilities.
The Inventor is likely the first of the hidden classes you'll encounter, as depending on who your starting character is you might begin the game with it right on your doorstep. Once that happens, you'll unlock it quite quickly - but then faced with further quests to make it viable. This guide covers all that, from unlock to having one of the best jobs in the game.
Octopath Traveler 2 Inventor Job guide & Unlock
This guide exists to help you through the trials and tribulations associated with the Inventor in Octopath Traveler 2 - which does get rather testing. The test starts out with Arkar, a top-hatted steampunky NPC you'll find in a dilapidated building at the New Delsta Highroad, not far from the Eastern exit of New Delstra city itself.
It's important to remember that unlike the Secondary Jobs, the Inventor is like the other Octopath 2 Secret Jobs in that there's no indication on the map until you actually discover it - you'll need to enter this random building and talk to the NPC, and that'll kick off the storyline, which takes the form of the A Genius Inventor side quest.
That's complicated enough in itself... but then things get more so - which is where this guide really kicks in.
Upgrading and Improving the Inventor Job Class
Okay, so - the Inventor is an entirely unique job class in Octopath Traveler 2. Unlike the rest of the jobs in the game including two of the other secret jobs (the Arcanist, and Conjurer), the Inventor does not require JP to learn new abilities, but requires a completely different method. This is similar to only one other job, the Armsmaster.
By examining the glass showcase of Arkar's building, you will find that each invention requires a set of materials to build. Once the invention is invented, you will obtain new abilities for the inventor related to that invention. The starting abilities for the inventor might seem a bit lackluster, but once you get a good amount of abilities, you will find this job to be extremely strong.
