Why level 0? It's simple: all players start with this level in the game. To get the next one, you need to accumulate experience, receiving it for tasks or killing mobs. But I didn't try to grow in levels like everyone else in my group did. After all, I had a Plan! True, if he fails, then he will have to grow in levels like everyone else. All players have this function of stopping growth in levels. You just don't get experience and that's it. Rarely does anyone use it, because at first glance it doesn’t provide any benefits. But if you carry out tests, you will notice that all the characteristics and crafts grow a little faster. That’s why I’m the only one among us.
