Crippling

Weapon Special Rule
Weapon systems with the Crippling characteristic inflict crippling damage when they score one or more critical hits. In addition, to any normal Hull Damage, Crippling damage is incurred regardless of the number of Hull points actually inflicted providing one or more Hull damage is suffered by the target. If a target ship is reduced to 50% hull or below by the attack it will need to make two Cripping Damage rolls and apply both of them.

If a weapon with the Crippling rule is affected by another rule which would make Critical Hits automatic (such as the Particle rule) then the roll you would have needed to achieve a Critical Hit is the roll required for the Crippling rule to take effect.For example, a Lock 3 + weapon would need a 5 or 6 to make an additional roll on the Crippling table.
