Monster Manual Errata                                             Home Up

Errata for the early prints of the Monster Manual, first released in Jun 1978.  Unlike the errata for the Dungeon Masters Guide, which were incorporated all at once (into the "Revised Edition" of Dec 1979), the Monster Manual changes were gradually introduced over a period of two years, up to the "final" Fourth print.  The print in which the particular change was incorporated is noted in blue text below (note that a few changes never actually made it into any print).  These corrections originally appeared as an article in Dragon Magazine #35.

An error recently pointed out to us -- and never corrected in any print -- occurs on the back cover, in the Quasit's statistics.  The Hit Dice, Magic Resistance, # of Attacks, and Damage/Attack is different from the statistics listed inside the book.

A second never-corrected error: in the stats block for the Giant Water Beetle, it is listed as having a ground speed 3" (correct), and a flying speed of 12" (incorrect).  It's missing the second forward slash (3"//12") which would correctly identify the 12" as swimming speed.  Thanks to Samuel Thomas for this info.

Additionally, some monster pictures were left out of early prints, and gradually inserted in later prints (up to the "final" Fourth print).  The list of missing pictures per print is as follows (thanks to Larry Helm, Rene Hurka, and Antoine Pressard for this info):

First:  Ape (Carnivorous), Centaur, Doppleganger, Dryad, Eye of the Deep, Fungi, Gar, Ghost, Hobgoblin, Intellect Devourer, Kobold, Men (Berserker), Merman, Mummy, Otyugh, Pegasus, Pixie, Purple Worm, Rat (Giant, Sumatran), Skeleton, Slug, Sprite

Second:  Ape (Carnivorous), Eye of the Deep, Fungi, Otyugh, Rat (Giant, Sumatran)

Third:  Eye of the Deep, Fungi, Otyugh, Rat (Giant, Sumatran)

Fourth:  All pictures present.  Note that some monsters still do not have an accompanying illustration, but the Fourth print is as good as it gets.

Lastly, three pieces of artwork were changed between the First and Second prints, obstensibly because Dave Sutherland was forced to rush several pieces and was unhappy how they turned out. The three pieces are: the Chimera, the Type III Demon, and the Nightmare (thanks to Mike Ferdie for this info).
