When a PC is fighting in the dark and rolls a natural 20 is there still a 50% chance of a miss? The rules say the following about fighting in the dark:
All opponents have total concealment from a blinded creature, so the blinded creature has a 50% miss chance in combat.
But the rules also say the following for a Natural 20:
A natural 20 (the d20 comes up 20) is always a hit. A natural 20 is also a Critical Threat—a possible critical hit.
So if I roll a 20 on the die is a percentage roll required?
