Saving the world on a Sunday afternoon
The Monster Compendium contains a selection of stats for various monsters and creatures that have appeared on games to offer new GMs an example of what makes for an interesting encounter, as well as commentary on how to change them to fit the circumstances.
They are not intended to be a rigid set of stats that must be used, but rather for guidance and ideas for how to make an encounter fun and unique.
Experienced GMs are welcome to submit their own stats for inclusion if they choose. Stats should come with a rank bracket they were intended for as a minimum and optionally any commentary on why certain choices were made.
