"As a 1 star Mage you can use magic power reinforcement to enhance any part of your body, but reinforcement is one of the lesser abilities of a Mage. To be honest, it can't even be called a special ability and is only useful against weaker Mages or non-Mages. That is why you have to have special training in all kinds of martial arts, these exist to help you use your strength more efficiently.
In fact, it is actually possible for a non-Mage with training in martial arts to defeat a 1 star Mage. In front of a person with training even if you are a Mage, you will only just be another slightly stronger human. As long as he uses some good technique he can put you down easily. So you have to train in fighting styles and martial arts, this also applies up the ladder for higher levels."
