Imagine you have 5 different types of magic that you can learn, like 5 different types of toys you can play with. Each type of magic is special and has its own rules you have to follow to use it properly.
A master of the five magics is someone who has learned how to use each of these 5 types of magic to their fullest potential. They are like a grown-up who knows how to play with all 5 toys in the best way possible.
But it's not easy to become a master of the five magics! You have to work hard and practice a lot to learn each type of magic, just like you have to practice to become really good at using each toy.
But once you become a master of the five magics, you can do amazing things like make objects move with your mind, see things that are far away, and even make yourself invisible! It's like having superpowers that only a few people know how to use.
