About Monstro.cc

Monstro.cc is a bestiary tracking OSR (Old-School Renaissance) monsters across multiple sourcebooks and game systems. My goal is to create a centralized, searchable, and interconnected database of classic fantasy monsters from the OSR ecosystem.

The Data

All monster statistics are extracted from publicly available System Reference Documents (SRDs). This is an ongoing project - if you spot an error, please email [email protected].
