How It WorksEdit

When a player rolls a natural 1 on a d20, it's a miss. However, to add a bit of drama to the game, have them roll a confirm miss or critically fumble. If they get a 6 or more on another d20 roll, the attack is a simple miss. If they roll a 5 or less, roll a d100 on the fumble chart.
