The job system isn’t as simple as it first appears in Octopath Traveler 2. After starting your adventure, you’ll earn JP — Job Points — and use them to unlock new skills for your characters.

Even after starting this quest, it isn’t totally clear how to unlock secondary job for your characters. To unlock more jobs, check the glass cases in the Inventor’s House.

For each invention you unlock, you’ll add a new skill to your Inventor Secondary Job.
