It entails a bargain with Bagrivyek, the goblin deity of cooperation. The God offers them a deal they can’t refuse, significant magical assistance for their quest, should they become its test subjects in a fight to the death with some of its elite troops. Devils that have been infected with a special substance, which is called soul-ichor and was created by a psychomancer, in search of his own power. The heroes will have a chance to interact with a god and bargain with it, a fight to the death at the Hellbent Fighting Pits, and also get a chance to learn of or even be introduced into a long-forgotten school of magic. Will the players reap all the benefits of this god-deal, or suffer the consequences of failing?

  • An introduction to a new school of magic and a new specialist wizard – Psychomancy.
  • One DM and one player version-map for your tables or online virtual TTRPG platforms.
  • A new very rare magical item (potion), which can significantly change any creature it comes in contact with, with unpredictable effects- the Soul Ichor!

  • Quotes from unknown and famous people of the Forgotten Realms for each chapter.



Important note: This adventure is designed as a supplement for Baldur’s Gate: Descend into Avernus. DM’s can use the scenario in other campaigns, in case the goblin god Bargrivyek or its avatar is encountered.

What does the following mean: "Immunity to damage from normal weapons, resistance to slashing, piercing and bludgeoning damage from non magical weapons that aren’t silvered"? Why is there immunity and resistance in this paragraph, and then resistance afterwards to the "same" thing?

Thank you Nicolai for spotting this error. It should just say : "You gain immunity to slashing, piercing and bludgeoning damage from non magical weapons that aren't silvered"
It has now been amended and an updated file has been uploaded. Thanks and please let us know if you have enjoyed this module.

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.
