I see one line in the SRD stating:
A critical hit means that you roll your damage more than once, with all your usual bonuses, and add the rolls together. Unless otherwise specified, the threat range for a critical hit on an attack roll is 20, and the multiplier is ×2.
However, that is immediately followed by the line:
Exception: Extra damage dice over and above a weapon’s normal damage is not multiplied when you score a critical hit.
At the moment, I have a +2 strength bonus and a +2 weapon specialization bonus.
My question is this: On a critical hit, do I get to add those bonuses to my total twice?
