DM’s Guide to Greyhawk 576

Hello all!

I figured it was best to get this out into the wild while the OGL1.0a was still applicable.

This is a book originally intended to be one of a pair, with everything you need to DM a 5th Edition D&D game in the World of Greyhawk, except the maps.

Contents include Campaigning in the World of Greyhawk, History of the Flanaess, Calendar and Seasons, Weather, Cosmology, Lands and Wildernesses of the Flanaess, Magic Items, and Monsters.

You can download the book here. Enjoy!

Written by 

Wargamer and RPG'er since the 1970's, author of Adventures Dark and Deep, Castle of the Mad Archmage, and other things, and proprietor of the Greyhawk Grognard blog.

  1. Very impressive work, even just skimming it . . . Wait, “Orange cats are bad luck in Blackmoor?” Oh, you’re canceled, Joe. You’ll be hearing from the Anti-cat Defamation League shortly.

  2. This is great stuff! Thanks so much for creating and sharing it! Regarding the rulers, 5E, as I understand it, really doesn’t have levels beyond 20th, but a number of the rulers here exceed that through multi-classing or following the old fighter/thief/bard progression. Thoughts on how they should be handled?

      1. Interesting! Wasn’t aware of that. Back in 3E days I was deeply intrigued with epic levels, but my 5E campaign so far has characters at 3rd level after a year of play, so no imminent need for rules like these…

  3. Thanks for putting this out. That section on grues are particularly timely for me.

    I have a question about the Spell Immunities sections: as written it strikes me that they would have an effect, but were they all meant to say “will NOT have any effect…” ?
