Rules edition: This guide separates legacy 2014 race rules, optional character-origin rules from Tasha’s Cauldron of Everything, and revised 2024 species/background rules. Check the edition and source allowed by your Dungeon Master before applying a trait. The same species name can refer to different rules in different books.
Choose the rules version first
Under the 2014 Player’s Handbook, a race—and sometimes a subrace—provides the traits printed in that source, including its ability-score increases. Tasha’s Cauldron of Everything offers optional origin-customization rules that can change some ability-score increases and proficiencies when the DM allows them. These options do not automatically update every older race.
The revised 2024 rules use the term species. A species gives its listed traits; ability-score increases and an Origin feat come from the character’s background. Do not add a 2014 racial ability-score increase to a 2024 background unless your table is using a specific compatibility rule that says to do so.
Read the exact source for each trait
Books published after the 2014 Player’s Handbook sometimes present updated versions of species that first appeared elsewhere. For example, Mordenkainen Presents: Monsters of the Multiverse revises several earlier options. A guide should name the version it uses, and a character should use one complete trait package rather than combining features with the same name from different books.
Pay attention to a trait’s action, range, uses, recovery, and level prerequisites. A movement feature, spell, resistance, or proficiency is useful only as its printed wording allows. If an option is tied to a campaign setting, confirm that the source fits the world your group is playing in.
Build the character you want to play
No race or species is automatically best for a class. Set ability scores using the character-creation rules paired with your class, then compare the traits you expect to use in your campaign. Movement, senses, defenses, proficiencies, and once-per-rest features can matter in different ways depending on the adventure. A character’s ancestry also does not prescribe their personality, morality, culture, or how strangers must treat them; use the setting and the character’s own story.
