Haedrig can be trained in his art, provided the player gives him [[Salvaging|Salvaging Supplies]] and some Gold. Upon giving these materials to him (these come in sets, for example, 4 Common Scraps and 500 gold for 1 upgrade), Haedrig gains experience. Once he levels up, Haedrig offers more crafting recipes, more/better items sold and is visually Upgraded.
