The magic in Dungeons & Dragons consists of the spells and magic systems used in the settings of the role-playing game Dungeons & Dragons (D&D). D&D defined the genre of fantasy role-playing games, and remains the most popular table-top version. Many of the original concepts have become widely used in the role-playing community across many different fictional worlds, as well as across all manner of popular media including books, board games, video games, and films.
