From publisher blurb:
Running a game of MyD20 Lite just got a lot easier! The MyD20 Lite Bestiary: Common Creatures is intended to provide the Referee with a basic list of more than sixty different monsters that are common to many fantasy campaigns, some of which have multiple stat blocks for variant monsters, leading to almost seventy-five different unique monsters ready to populate your adventures!
In addition, you'll also find rules on how to create your own monsters in the MyD20 Lite system!
MyD20 Lite's small, spartan rule-set frees up your creativity to create a fantasy role-playing experience without the hassles found with larger, more complex gaming systems.
