The minimum for each primary statistic is 1 and the maximum is 10. These boundaries can never be broken, even with bonuses or maluses. Each statistic directly modifies certain derived statistics. In addition, every skill is tied to a primary statistic. Some perks require certain minimum attribute values as well.

Increasing attributes[]


  • Lorri at Lost Hills can provide operations to raise each of your stats (except Luck and Charisma) by 1, although it incurs a significant cost in money and time. It's possible to receive two Intelligence upgrades, as if the player character has less than 4 intelligence, Lorri will offer an intelligence upgrade at a significantly lower cost.
  • Chuck in Adytum can raise Luck by 1.
  • Patrick the Celt's encounter can increase Charisma by 1.


Behind the scenes[]

As Fallout did not support #define commands, scripting relies on direct references. As such, scripts reference primary statistics in the following fashion:

0 Strength
1 Perception
2 Endurance
3 Charisma
4 Intelligence
5 Agility
6 Luck 

Eg.: get_critter_stat(dude_obj,3) tells the game to check the player character's Charisma.
