Defense is a derived statistic in Fallout: The Roleplaying Game.

Characteristics

In Fallout: The Roleplaying Game, defense is one of two statistics by which a character can avoid damage; the other being various damage resistance types. Defense occupies the "first step" for an attack to land in-combat and simulates the difficulty of landing a hit on targets. Defense is entirely derived from the Agility attribute.

In gameplay, an enemy rolling 2d20 against a character must meet or exceed the total defense of the character, i.e. a character in optimal range with a defense of 2 has a difficulty of 2 to hit so 2 or more success must be made to achieve a hit.

Initial level

The overextended complication can decrease defense for a single round, should the character be using a melee, throwing, or unarmed weapon.

Raising defense

  • Defense can be temporarily increased by 1 when succeeding a Defend major action during combat.
  • Weapons with the Parry quality can increase defense from melee attacks by spending one action point.
  • Stealth Boys increase defense by +2 even while detected.
  • Emergency Protocols power armor mod raises defense by 1 while health is 1/4th its total maximum.
  • Wasteland Survival Guide: Self Defense Secrets increases defense by 1 against melee attacks.

Related perks

  • The Moving Target perk increases defense by 1 when using the sprint major action.
  • The Dodger perk reduces the difficulty of the defend major action.
