Ok, I didn\'t really explain it that well... Let me explain the multiplier better:
All skills would advance like this: gained x*y points in whatever
x = base points gained from action of using the skill
y = multiplier to make it easier/harder to learn
(both x and y are non-negative)
At the same time you gain points in a skill, the multipliers of other related/opposite skills would be slightly raised/lowered.
Example: Learn 0.5 points in a skill, with a multiplier of 2, get 1 point total. At the same time, all similar skills would get their multipliers increased and opposing skills would get their multipliers decreased.
