Portal:Dungeons & Dragons/Selected rulebook/5

Libris Mortis: The Book of Undead is a book which is an official supplement for the Dungeons and Dragons role-playing game, version 3.5. It is about the fictional undead within the D&D universe and comprises seven chapters, introducing new content for Dungeon Masters and players, as well as providing general information about undead.

It was received positively by reviewers, with praise for its material for Dungeon Masters and its illustrations, but received criticism for its weak player-oriented content. The book was the second in the series of books about specific monster types, the first being Draconomicon. Similar books published since include Lords of Madness. Libris Mortis included content from older books, such as Tome and Blood and the Book of Vile Darkness, that had been reworked.
