Characters are required to spend many weeks training "after" an experience-generating adventure in order to increase skill levels. Weapons training typically requires the aid of a person of greater skill than the player, and hiring a weapon-master can be expensive as well. Often, a group will return to town laden with gold, only to realize that between the several months spent training (room & board) and the cost of experts to assist them with training, most of the money is already spent! It is also possible that a character may actually "be" the expert in his/her local area, and thus might have to travel some distance to receive instruction from a person of greater ability.
