Defense

Defense is a derived statistic

Gameplay
In Fallout: The Roleplaying Game, Defense allows a character to avoid damage. 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.

An enemy rolling 2d20 against a character must meet or exceed the total defense of the character. If a character has a Defense value of 2, the enemy must roll 2 successes in order for their attack to hit.

Initial Level

 * Agility 1-8: +1 Defense
 * Agility 9+: +2 Defense

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. An additional point is added if the player characters spends two action points.
 * Weapons with the Parry quality can increase Defense by +1 against melee attacks by spending one action point.
 * Stealth Boys increase defense by +2 even while detected.
 * The Emergency Protocols Power Armor mod increases Defense by +1 while health is 1/4th its maximum.
 * Wasteland Survival Guide: Self Defense Secrets increases Defense by +1 against melee attacks.
