Nah, the whole thing would be kinda transparent.
Let\'s say you\'re a lumberjack, each day you chop wood to get a living, what stat will increase? Not charisma, strength!
If you use an axe all the time, your skill in using an axe will go up, and you will, let\'s say work faster
If you go to use a saw instead, and use it quite long, you will forget some axe skill because you haven\'t practised it.
Not really levels were you can add charisma or agility points for killing mosters/choping wood
Reserved for future correction, not a single bit of the information may be right, but I sure hope so
