Tanners are Forgotten Leatherworking Assets that can be hired to perform various tasks in order to raise the character's Forgotten Leatherworking level and produce armor for the Trickster Rogue. Tanners are required assets needed to complete most Forgotten Leatherworking tasks from levels 7 to 13. They can also be added to tasks that offer optional personnel asset slots to reduce the completion time for those tasks.
At Forgotten Leatherworking level 7, a Tanner can be hired by completing a task that trades 4 Skinners into 1 Tanner. Tanners can be traded and sold on the auction house.
Higher tiered personnel, such as the [Assistant Leatherworker] can be used instead of Tanners for tasks that call for them.
