Expand Your BALDUR'S GATE: DESCENT INTO AVERNUS Campaign with ABYSSAL INCURSION
James Introcaso recently released a new unofficial expansion for Baldur’s Gate: Descent into Avernus called Abyssal Incursion. This expansion requires the main adventure but adds three new locations, 2 new artifacts, and a variety of new challenges for adventuring parties who want to face Demon Lords. Each of the locations even features a variety of story hooks and NPCs for you to use and further immerse your players in the adventure.
You can purchase Abyssal Incursion from the DMs Guild for $4.95.
