Octopath Traveler - Battle-tested Weapons/Shield locations

There are 2 ways to acquire these weapons, one is post game guaranteed and the other is a low percent drop from certain 10 star NPC's. The guaranteed methods of obtaining are only available after completing a certain character's chapter 4. I will give the location of the NPC that drops and also the location of the weapon to purchase/steal from. The drop rate for challenging is 2% so it may take a while to get the items to drop.
