In Diablo III, Haedrig Eamon is the crafting artisan who specializes in blacksmithing.
Haedrig is introduced early in the campaign and becomes a permanent artisan who can train to craft weapons and armor. Players provide gold and crafting materials to improve his training level, which unlocks additional recipes and stronger equipment.
His personal story is also tied to the early campaign. Haedrig asks the player to help him deal with a family crisis and later joins the player’s settlement. This makes him both a gameplay service provider and a recurring character in the narrative.
Covetous Shen is Diablo III’s jeweler, while Myriam the Mystic is the artisan who enchants and transmogrifies equipment. Zoltun Kulle is a major lore character associated with the Black Soulstone, not the game’s ordinary blacksmith artisan.
