All right, here's the situation.
Your player has a Vorpal Sword that is five foot in length. He is facing a large Dragon that has a ten foot neck in diameter.
Even if the players rolls a natural 20, would you allow a five foot vorpal sword to cut the head off of a dragon, or any beast, that has a neck diameter of ten feet, or more, would you allow the entire head of the beast be chopped off?
