How do I spend my points?

[ddemers]

if I understand skill correctly, i get 5 points for every level i gain. Also if I have at least 1 point in a skill it will level as I use it.

So technically I only need a certain number of skills to get everything to 1, after that what do I spend the points on?

I dint want to use them to up existing skills just in case I was supposed to save them for something.
