Even if it is not in cf, it can be considered in a different place, the amount of charisma points of skills can be reduced or more charisma points can be given for the killed character. For example, killing 1 character costs 50 or 100 charisma points.
Everyone who has written on the subject agrees. Even if not in cf mobs, there should be an alternative to earning these charisma points for +120 level players. The asking price for the item called carving... is too high and the amount of gold available on the server is very small.
