Octopath Traveler 2: How To Unlock All Inventor Skills | Advanced Job Item Locations Guide

To unlock the true power of the Inventor job in Octopath Traveler 2, you’ll need to search the continent for rare items. Some of these items can only be found in hidden treasure chests in obscure dungeons, or carried by powerful NPCs that’ll only drop their weapon if you use specific path actions. Tracking down the items for this job is a real pain — and JP is pointless, you can only earn new abilities by helping the inventor craft new gadgets. That makes this one of the best (and most annoying) Job classes in the game. If you’ve searched everywhere and need a helping hand pointing out the last locations, check out the item list below for exact instructions.

All Inventor Skills | Crafting Item Locations

The Inventor is an Advanced Class located east of New Delsta on the New Delsta Highroad. Find the inventor’s house and talk to him to unlock the job. Instead of using JP, you’ll need to find items to deliver to the Inventor. Bring the right items and the Inventor will craft new gadgets — these gadgets become skills.

Finding all the items required to craft these skills can be difficult. Below, you’ll find locations for every item, broken up by each skill.

• Elemental Bomb Bottle: Deal the same type of damage as a single foe’s exposed elemental weak points 1 time.
  • Fire Soulstone: New Delsta Flats – Sold by a random merchant in the Black Market. Vendor only appears at night. Swap between night & day to swatch vendors.
