Suppose a duelist have stunning critical. What happens if he confirms a critical hit and use crippling critical to lower the enemy saving trhow by -4. Does the enemy use his normal fort save against the stunning efect or his normal fort save -4?.
Saving throw -4 seems to make the most sense. Largely because reducing the saves otherwise seems kind of useless for the solo duelist. You get to apply your effects in the order most beneficial to you, I'd say.
somebody else have an opinion? it seems like cornugon smash+sickening critical+crippling critical+ stunning critical could end an encounter (the enemy would have -8 to his ST).
