Trainers increase certain skills in exchange for gold. Training can be used five times per level only. Training a skill in this way costs 10 x current skill level (i.e., raising a skill from 24 to 25 costs 240g). Note that current skill level for the purpose of the payment is calculated after modifiers from i.e. enchanted armor. Therefore, it is cheaper if skill-boosting gear is unequipped before entering a training session.
