Note: Light spoilers for Baldur's Gate: Descent into Avernus in this description!

Expand your Baldur's Gate: Descent into Avernus game with three new adventure locations, complete with plot hooks and NPCs, plus two new artifacts: Baphomet's glaive, Heartcleaver, and Yeenoghu's flail, Butcher! This supplement adds more challenges for characters of levels 8 and above who dare face Demon Lords on the River Styx.

  • Face Baphomet aboard his war barge!
  • Go inside the belly of Yeenoghu's beast, Crokek'toeck (literally)!
  • Get a little Eberron in your Forgotten Realms by acquiring an elemental galleon made to sail the River Styx... if you can deal with the yugoloths defending it!
  • Maps and a printer friendly version included as separate files!
The Blood War rages in Avernus. Will you sieze opportunity, fight back the hordes, or perish?

Map sizes would be very useful. As it stands, I've given up and just use the maps with no grid.

Does anyone know what the map sizes are for the barge?

Bookmarks, always include bookmarks. Everything looks great, art, items, adventure, but damn if not having bookmarks makes looking around the document more of a chore.

The file is MASSIVE. 800 MB, I think? This should be indicated somehow. It also seems like a huge waste since it is full of duplicates.

I misread the description as "Face Baphomet aboard his war bagel" and I got really excited for a minute

Are the maps compatible with Roll20 or other virtual tabletop sites? This looks awesome!

Yes! You can easily upload them to Roll20 on any other VTT.

Do you happen to know the grid size for the maps? I don't see it mentioned anywhere.

What level characters is this adventure for? From the description I can tell that it's for higher level PCs, but if anyone can share ideally what level the characters should be at, that would be great.

Hey Rachit! Good question. The default character level for these locations is 8 or 9, though there are some tougher encounters (like demon lords) that should be avoided by the characters if they are that low level (via sneaking or running away).

Rules Edition(s)
Original electronic
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.
