Say Ten Numb rolls two crits, and the defender rolls one evade. How many get through? To put it another way, which of the two crits can't be cancelled?
One of those crits is getting through, because there's no evade to cancel it. Does the second one get through because it can't be cancelled, or can the defender say "no, the other one was the one that can't be cancelled"?
