Banned because this is the way xp works in minecraft imo:
After killing mobs you get experience on fighting with them, when you have an enchanting table and lapis you are able to wirte with lapis as ink ways ti fight them and then you create enchantements, you wirte on tools, weapons, armor or books. The same goes for ores, you get experience with mining ores or smelting them. When you add bookshelvs you arw aboe to write more about your experiences,
