Kenshi Wiki
Stats Affected: Description:
Toughness is both physical and mental. It's how you survive out in the desert. Physically it's your ability to take a beating and survive. Mentally it's an attitude forged from harsh experience. Do you pass out from your wounds like a sissy, or do you force yourself to struggle to your feet again? Do you panic and bleed out or can you stay calm enough to lower your heart rate and let the blood clot?
-Damage resistance
-Martial arts damage
-Chance to resist stealth knock-outs
-Knockout time
Ways to Train:
-Getting hurt, getting beaten up, losing battles
-Not wearing armour, taking more damage
-Get up and fight instead of playing dead

Toughness was introduced in version 0.61.0 of Kenshi and appears to replace a stat that was previously known as "Warrior Spirit" (though it was never actually implemented). Toughness determines a character's Damage Resistance and KO point (Knock Out Point).

  • Damage Resistance: Starting value for a character at 0 toughness is -0.65 and at level 100 is 0.65. For each level of Toughness the characters Damage Resistance will increase by 0.01 meaning Toughness at 51 or greater the character takes less damage from attacks while levels 49 and lower take increased damage. 
  • KO point: The greater the Toughness this number will grow in negative value. Current range is -10 to -80 (-80 is a character at maxed Toughness).
Loading Screen Tips
If your whole squad is taken down, any survivors will play dead until the enemy is out of range. You can force them to get up anyway by giving them an order, which will also improve their Toughness stat.

Improving Toughness

The following methods are ways of improving a character's Toughness (quoted directly from In-game):

  • Getting hurt, getting beaten up, losing battles
  • Get up and fight when you should be playing dead
  • Bonuses if you are fighting critically wounded
  • Making certain (often foolish) dialogue choices
    • "It means starting fight with drunks, bandits, or any other usually hostile factions through dialog"
  • Once your health drops below your KO point [Specific to your character] your health becomes critical and you won't be able to get back up again. You will need healing and go into a coma.

Toughness combat exp scales based on the amount of damage received relative to your toughness level, using the skill diff modifiers in the FCS. Damage that is resisted via armour or toughness itself IS still counted for this purpose, even though the damage might be nullified.

  • At 25 damage or lower than your toughness level, you will receive x0.1 the amount of exp.
  • At 10 damage over your toughness level, you will receive x2 exp. This scales up to x6 exp at 50 damage over your toughness level.
