McMMO's main function is to incorporate an RPG-like skill system that players will have access to right from the beginning. Depending on how much a certain tool is used or a certain action is performed, players will gain experience that will eventually add bonuses such as double drops, rare drops, or ability enhancement.

You can earn ranks in-game by levelling up your MCMMO Power level. Power level is sum of all different skill levels.

Skills are mentioned down below.
