(You still have to correct the size)<br/>This time you spent 8 SP when you got 10: you have 2 more points to assign.<br/>As explained before, to increase by one point a skill level you have to spend as many skill points as the skill level you're gonna reach (minimum 1 SP). So, if you upgrade a skill from 0 to 1, you spend 1 point; if you upgrade from 1 to 2, you spend 2, from 2 to 3 you spend 3 and so on.
