When determining your ability scores, you increase one of those scores by 2 and increase a different score by 1, or you increase three different scores by 1. You follow this rule regardless of the method you use to determine the scores, such as rolling or point buy. This is shared across all races presented here.

Your class’s “Quick Build” section offers suggestions on which scores to increase. You’re free to follow those suggestions or to ignore them. Whichever scores you decide to increase, none of the scores can be raised above 20.
