No, actually, they're related but not identical. Rolling a 20 is an auto-hit and is also a critical, but you can roll a critical without it being an auto-hit when you have an expanded critical range. Likewise, you can have an attack that auto hits but is not a critical hit (like magic missile).The auto-hit is part of scoring a critical though?![]()
The difference between the average damage of a -X/+2X attack and a normal attack does not change when you factor in criticals.
You can run the math and find out.
