A base character has a 5 out of 10 rating in each. But, never fear, you can adjust to your hearts content. In fact any combination is possible, you get to allocate the points any way you desire. These skills come in mighty handy as you roam the world. These start higher and go up more quickly than the others.
Many approaches are possible.
I tried a sharpshooting assassin and a charismatic liar. I finished the game with both, though I admit it was a lot easier with the liar since I already knew the basics of what I needed to do from the assassin. Still, many styles and approaches can work. Just be sure you have some reasonable ranged combat skills, you will need them. These can have a big impact on the game, choose wisely.
