Megadungeon Monster Manual

Selected Option:

The Megadungeon Monster Manual is an OSR fantasy role-playing game supplement for Barrowmaze, The Forbidden Caverns of Archaia, HighFell: The Drifting Dungeon, and Dwarrowdeep. The book brings together the most fearsome monsters from these megadungeons and combines them into a single volume.

The Megadungeon Monster Manual will keep your players on their toes and your campaign going strong for years. The creatures are compatible with any early edition ruleset or their clones.

The MMM is brought to you by the Old School Renaissance (so don’t forget your 10’ pole).

Check my drivethrurpg profile for all sorts of additional Barrowmaze material.

Any chance to see an example monster or two with their illustrations? Not any under Preview. Thanks in advance for your response.

Has what I need, and I will make good use of it, but I must say for $25-$35 PDFs, the lack of bookmarks is an annoyance as I'm going to need to do it myself... again.

Just bought this and all the other stuff from Greg. If you love old-school D&D these are a no brainer. Use them as is or pick them apart to add to your own concoctions. Awesome art and good clean layout too. Excellent.

Just got my print copy today. Very pleased, beautiful book and artwork.

I plan on using this for OSE solo. Can I also use the same stat blocks for 1st edition Advanced D&D as is?

Out of curiosity, how many pages is this?

Does the Monster Manual have 5e stat blocks to help supplement the 5e versions of the various megadungeon modules?
Customer avatar

Just OSR stats. Not sure if he will do a 5E version given recent events.

A longer preview to see some of what we'd actually be getting beyond a list of names would be appreciated.

I'd love to see a stat block. I'd like to know if it uses ascending AC, uses all d8s for HD, has the old school style saves or the cleaner/modern saves, etc.

It uses the classic BX format, i.e. descending AC, d8s for HD, and the old school saves. The entries for those aspects look like:
Armor Class: 6
Hit Dice: 1+1
Save: F1

Could be helpful if you are putting all the Gillespie mega-dungeons on the Outdoor Survival game map as one campaign. I'd like to see an expanded "Northern Reaches Gazetteer" with more details on each area, culture/racial variant races, etc.

Yeah, not sure why I'd need this, given everything else that is already available. Please provide additional samples of art and statblocks.

What I would really love to see is a couple of example monsters stats. To see how they fill out and if they would work for me. I use Labby Lord and O to 2nd edition. So seeing if they use similar treasure types and morale roles is key for me. Or something equivalent.

There isnt an encounter table, is there? Any listings based on enviroment? Not listed in index but it could have continued on the next page. I understand, since this is really just sharing a lot of monsters from several megadungeons with other DMs for use in their games. I just had to ask. Thanks in advance for your response.

PS I agree with Jeremy, a sample of the art with the samples requested above would be just plus.

Any extended samples of the artwork?

I would second that. Happy to purchase but I would like to see some of the actual monster artwork.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
