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.

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.

If you are replacing your race with a lineage, replace any Ability Score Increase you previously had with these.

Every creature in D&D, including every player character, has a special tag in the rules that identifies the type of creature they are. Most player characters are of the Humanoid type. A race option presented here tells you what your character’s creature type is.

Here’s a list of the game’s creature types in alphabetical order: Aberration, Beast, Celestial, Construct, Dragon, Elemental, Fey, Fiend, Giant, Humanoid, Monstrosity, Ooze, Plant, Undead. These types don’t have rules themselves, but some rules in the game affect creatures of certain types in different ways. For example, the text of the cure wounds spell specifies that the spell doesn’t work on a creature of the Construct type.
