Monsters and Rules for Ravenloft and the Curse of Strahd
From the introduction:
This book contains a wealth of classic monsters for the Ravenloft Campaign Setting, updated from both the 2nd Edition and 3rd Edition of the Dungeons & Dragons rulesets.
The monsters of this book were primarily found in Ravenloft Monstrous Compendium Appendices I & II and Ravenloft Monstrous Compendium Appendix III: Creatures of Darkness, and full information on the habitat, societies, and ecologies of these monsters is included in those products. I heartily recommend these products be purchased for full use of this PDF. However, the monster statblocks are complete, and self-contained, so there is all the information needed to run each of these monsters in this book.
All entries have been updated to conform with the format and standards established in Monster Manual (D&D 5e).
