Attack Roll
An attack roll represents one starship’s attempt to strike another on its turn in a round. Most starships are armed with ranged weapons aimed by gunners. When a starship makes an attack roll, roll 1d20 and add the appropriate modifiers (described below). If the result equals or beats the target’s Defense, the attack hits and deals damage. A starship’s attack roll is:
1d20 + gunner’s ranged attack bonus + range penalty + starship’s size modifier + targeting system’s equipment bonus
Gunner’s Ranged Attack Bonus: Unless noted otherwise, all starship gunners are assumed to have the Starship Gunnery feat. Without this feat, a starship gunner takes a –4 nonproficient penalty on attack rolls with starship weapons.
For simplicity, all gunners aboard a starship have identical ranged attack bonuses.
Range Penalty: The range penalty for a ranged weapon depends on what weapon the starship is using and the distance to the target. All ranged weapons have a range increment, as noted in Table: Starship Weapons.
As with character weapons, any attack from a distance of less than one range increment is not penalized for range. However, each full range increment causes a cumulative –2 penalty on the attack roll.
A beam weapon has a maximum range of 10 increments. A projectile weapon has an unlimited range, since projectiles don’t lose inertia in space. Starship’s Size Modifier: Starships are Huge, Gargantuan, or Colossal in size. Table: Starship Sizes notes the size modifiers for ships of different sizes. Targeting System’s Equipment Bonus: Most starships have computerized targeting systems to help gunners train weapons on targets. A standard targeting system provides an equipment bonus on the gunner’s attack roll depending on the ship’s size: Huge +1, Gargantuan +2, Colossal +3. Improved targeting systems (see Starship Sensors) grant higher bonuses. Table: Starship Sizes summarizes the targeting system equipment bonuses for ships of different sizes.
Automatic Misses and Hits: As in character combat, a natural 1 on the attack roll is always a miss. A natural 20 is always a hit. A natural 20 also always threatens a critical hit (see Critical Hits, below).
