Way to unlock: Automatically, during the Haven's Best and Brightest side quest.
The quest-giver: Blacksmith (M2,7)
This quest becomes available after you see the Blacksmith in the Northern part of Haven (Haven) (M2,7). From the Blacksmith, you learn how to upgrade and craft armors from the scrap. At the same time, you receive this simple quest. It consists in checking out the armor upgrading station (Modify Armor), right next to the Smith. Of course, you need to own an upgrade for the armor, which you can either find in the game world, or but from a Merchant.
