Rolls & Combat

The wasteland is dangerous, but it is not a dice grinder. Dice come out only when an outcome is uncertain and matters.

The Stretch Roll

Compare your skill to a task’s difficulty. Subtract your skill from the threshold.

0 or lessYou succeed without rolling.
1–5Roll a d20; 10+ succeeds.

11–15Roll a d20; 17+ succeeds.

21 or moreIt is a Wall: find another approach.

A raw attribute check uses that attribute × 10 as the skill value. You never roll for what your character says, believes, or decides.

Combat in one page

  • To hit: roll d20 + your weapon skill bonus (skill ÷ 10, rounded down) against 10 + the enemy’s Agility modifier.
  • Armor: Armor does not make someone harder to hit. It subtracts Damage Threshold first, then Damage Resistance reduces what remains. A successful hit always deals at least 1 damage.
  • Weapons: Weapons deal fixed damage—no damage dice.
  • Criticals: A natural 20 is a critical. At Luck 7–8, 19–20 crit; at Luck 9–10, 18–20 crit. A critical doubles final damage and may create a fitting tactical effect.
  • Fumbles: A natural 1 creates a complication, such as a jam, a bad position, or unwanted noise.

V.A.T.S.

Where the campaign makes V.A.T.S. available, it is a called-shot option. It gives +2 to hit and prevents movement while aiming.

Getting hurt and recovering

At 0 Health, you are incapacitated or dying. Stimpaks restore 30 + one-third of your Medicine skill.

Stress is exhaustion from hardship, injury, radiation, and withdrawal. At half your maximum you begin to suffer; at your maximum you collapse until rested.

Resolve is your mental resilience. At zero, you break under pressure in a way that respects your control over your character.

Rads use a 0–1000 scale. At 1000 rads, if radiation is what takes you to 0 Health, you may choose the optional Ghoul Protocol rather than ordinary death.
