I have a level system interwoven in the magic system of my novel. Before Tate Publishing went belly up, both ghostwriters loved it as a unique idea. Now before you bash it allow me to explain. The in-story reason for a level system is wizards were dying from storing too much magic in their bodies at once. In the euphoria of doing magic they ignored or missed the warning signs and would go out in a flashy implosion. It got so bad that wizards quit doing powerful magic for fear of death. One prominent wizard lobbied for a warning system to prevent death. He suggested using some of the extra magic in a flashy sizzle of magical sparks that no one can ignore. The idea caught like wildfire, a circle was formed and the level system was born. Levels one through fourteen has nothing to identify it, for magic is not as dangerous. From fifteen onward there is the leveling display, for example multicolored (if that's what the wizard is) sparks sizzle around the feet then spiral up around them in a single chain. At sixteen there is two, ect until level twenty where there is a fireworks display and a ring of sparks. It goes on and on in different styles of display with fireworks at every #0. Most wizards only reach around thirty as their natural born limit. Some are more powerful with a rare few going beyond forty. My level system is not "Oh you did this enough time here is a level up!" It's more of the "magic muscle" becoming stronger to allow the use of more magic without straining the magic muscle from overuse. Much like a body builder hitting their wall, they cannot store more magic once they reach their level wall. There are techniques wizards can learn to compress their magic storage but that is phsically demanding and only used to cast powerful spells they can't cast normally. It takes time and effort so it's only used in extreme cases. In magic battles wizards who level up tell their oponet how powerful they are and if they've settled in their level yet. For example, if a settled twenty challenges an unsettled level twenty-two and they evel to twenty-three then the twenty will often bow out and admit defeat. Or they bow out and turn the battle over to a demon, but that's a unicorn of a different color. That's basically it in a nut shell. Tell me what you think about my level system. Be gentle, I bruise easy.
