Starship Combat Damage
When a starship hits with a weapon, it deals damage according to the type of weapon (see Starship Weapons). Damage is deducted from the target’s current hit points. If a starship’s hit points are reduced to 0 or fewer the ship is in bad shape (see Starship Hit Points.)
Sometimes a starship weapon multiplies damage by some factor such as when it scores a critical hit. Just as in character combat, you can either roll the damage (with all modifiers) multiple times and total the results, or roll the damage once and multiply the result by the given multiplier.
Bonus damage represented as extra dice (such as from an Engineer’s weapon upgrade class ability, is an exception. Do not multiply bonus damage dice when a starship scores a critical hit.
