If you’re willing to play the game over and over again using the same character, there’s a way to save about twenty skill points. Your Intimidate and Charm ratings are automatically upped when you become a Spectre. If you play the game over again, and over again from there, your Charm and Intimidate skills will slowly increase as each play-through grants you Spectre status. This will thereafter allow you to put the points you would normally spend on Charm and/or Intimidate on something else, making your character even stronger.
