Moldvay Basic: Monsters

The Moldvay Basic rulebook did not merely draw upon the Holmes Basic rulebook for its list of Monsters, but introduced several changes, adapted creatures from the AD&D 1e Monster Manual, and introduced new monsters (underlined, below).*

*many of the new creatures had appeared in the newly updated, combined Monster & Treasure Assortment (1980), Sets One-Three: Levels One-Nine, for which a working draft of the new list of monsters may have been available
