Just wanted to put this there for people yet to figure it out:You can start learning a crafting vocation by talking with a Master or Mistress of Apprentices. You can talk to one of them again if you want to change your vocation later on.
Masters and Mistresses of Apprentices can be found in several towns:
Bree-land:
Combe: Jill Brushwood, Mistress of Apprentices
Bree-Town Crafting Hall: Old Roger Sorrel, Master of Apprentices
The Shire:
Michel Delving: Blossom Proudfoot, Mistress of Apprentices
Ered Luin:
Celondim: Golphedinir, Master of Apprentices
Gondamon: Alfwin, Master of Apprentices
Thorin's Hall: MorĂ³r, Master of Apprentices
North Downs:
Esteldin: Thentlaer, Master of Apprentices
The one in bree is the scrool just below the town crier.Have a good one!
