Smelters are Weaponsmithing Profession Assets that can be hired to perform various tasks from levels 1-6 in order to raise the character's Weaponsmithing level and produce weapons for the Great Weapon Fighter, Guardian Fighter, and Trickster Rogue. They can also be added to certain tasks that offer optional Person asset slots in order to reduce the completion time for those tasks.
Recruiting the first Smelter takes 5 seconds. At Weaponsmithing level 2, additional Smelters can be hired by completing a task, each taking 18 hours. At level 7, 4x Smelters can be upgraded to 1x [Grinder], which is needed for Weaponsmithing tasks at higher levels.
Smelters may be traded between players and bought or sold on the Tarmalune Auction House.
