I know that when a starship takes damage equlling 10% of its hull, it suffers a severity 1 critical hit. What if it takes multiple hits of less than that? Say a starship with 100 hull takes a hit that does 5 points, and then a hit that does 7 points. will the 12 points of damage total cause a sustained damage critical hit since the ship has taken greater than 10% of its hull in damage? Or does it all have to come from a single attack? Thanks.
