Wizards of the Coast has announced Mordenkainen’s Tome of Foes, a new supplement for its Dungeons & Dragons role playing game, releasing in May.

The 192-page Mordenkainen’s Tome of Foes introduces new monsters, playable character races, and historic lore about some of the most factious racial relationships in the realms.  Useful for both Dungeon Masters and players, the book offers new options for tiefling, elves, githyanki and githzerai characters, as well as extensive details on the historic schism between warring races. There are also new personality tables, a menagerie of new creatures, and dozens of new monsters. MSRP is $49.95.

Mordekainen’s Tome of Foes will release to WOTC Core level stores and above on May 18. A limited edition, alternate-art cover (by Vance Kelly) will also be available to hobby stores. Broad release is set for May 29.

See both covers in the gallery below.

WOTC’s last Dungeons & Dragons book, Xanthar’s Guide to Everything, became the fastest-selling D&D release in the game’s history last year (see “Record Broken at WotC”).
