This chart shows the cost in training points to increase your character's skill at each level.

P/M: The number of Physical and Mental training points required to increase this skill. For example, a skill which is 5/2 requires 5 physical and 2 mental training points.

(T): The number of times the skill can be trained per level. Note that each training doubles the cost. For example, a 5/2 skill trained three times would cost 5/2 + 10/4 + 20/8 = 35/14.

When training, you can convert between physical and mental points at twice the cost. For example, if you have 9 physical and 0 mental points, you can use them to train in a 5/2 skill.
