D&D Fiends and Foes is a new monster book for Dungeons and Dragons

Wizards of the Coast is releasing Fiends and Foes, a new monster book for Dungeons and Dragons, and Polygon has an exclusive first look at its opening pages.

The book focuses on the game's nastiest villains — fiends and other classic D&D antagonists — and appears to be a dedicated bestiary rather than a general rulebook. Beyond the title, the exclusive preview of the first pages, and the framing as a fresh look at the game's iconic evil creatures, no further details about pricing, page count, release date, or specific monster entries are available from the source.

Dungeons and Dragons has a long history of dedicated monster supplements alongside its core Monster Manual. Wizards of the Coast has been actively expanding the 2024 revised edition of D&D with new sourcebooks, and a villain-focused bestiary fits that pattern — giving Dungeon Masters a deeper toolkit for building encounters around the game's most recognizable evil factions, from demons and devils to other classic fiend types.

The preview was published on July 9, 2026. More details about the book's full contents and release window are likely to follow.
