To generate an ability score, roll four six-sided dice (4d6). Disregard the lowest die and total the three highest dice. This roll gives you a number between 3 (horrible) and 18 (tremendous). The average ability score for a typical individual is 10 or 11, but a character is not typical. The most common ability score for heroes are 12 and 13 (the average hero is above average). Make this roll six times, recording the result each time on a piece of paper.
