Our group recently had a character made helpless through a Hold Person spell, then a Coup De'grace was performed by a rouge type. (Red Mantis Assassin). The character attacked has moderate Fortification on his armor.
What I want to know is how this works. Fortification can stop Critical hits, and it can stop Sneak Attack damage. Is there only a single roll on the armor since there was only one attack, or is there multiple rolls on the armor to count for the two types of damage? (critical and sneak attack)
