Alright, here is the proficiency system. Everybody gets 2 points for each item they have (not all races have the same value), and can distribute them how they see fit, with no one proficiency being able to rise above 3. At second and third stages, you gain 1 point to spend freely wherever desired. This point may push a 3 into a 4, but it can not push a 4 into a 5.
1: They suck at this subject, most characters with a 1 in a given ability will try to avoid using it much in combat.
2: The character in question is average at the ability, relative to his stats.
3: The character in question is an expert at this ability.
4: The character is a total master in this ability.
