I see one line in the SRD stating:
you roll your damage more than once, with all your usual bonuses
However, that is immediately followed by the line:
Exception: Extra damage over and above a weapon’s normal damage is not multiplied when you score a critical hit.
My question is this: At the moment, I have a +2 strength bonus and a +2 weapon specialization bonus.
On a critical hit, do I get to add those bonuses to my total twice?
