When you reach the maximum level of 81, enter the player.setav block 15 code followed by player.advskill 50000. Each time you do this, you will advance by two levels (adding 2 perk points and allowing you to choose 10 extra points for Magicka, Health, or Stamina). Repeat the process until you have the desired amount of Perk Points. Note: You can restore the maximum level (and difficulty range) afterwards with the player.setlevel 81 code or any other level or difficulty range.
