Stats points are the points you use to boost your stats. They are those upgrades you get when your forehead is wet with sweat and your fingers hurt, since you have typed too much. They are the fruits of your efforts.
It goes like this:
You start with 30 overall points. You put them in any of the six main skills.
It will be limited to a maximum of 10 on the same stat for now, since starting with 40 strength plus race and class modifiers would be a bit unrealistic.
Each level, you gain three more stats points. There is no limit to how you can use these.
To know if you put all of your stats point, it's easy just use the following formula.
60(base points) + 27 + (lvl X 3) = total stats points
Let's say I am lvl 8, I should have no more than 111 stats points. Unless of course, some magic items or spells enhance my character. This is true no matter your class and race.
I think I've made myself perfectly clear, so don't try pointing at me saying "You're wrong", you jerk! I assure you I won't even bother telling you off.
I'll add on the stats' descriptions afterwards.
