Sanctum of the Fiend of Possession

This encounter is intended for four 3rd level characters

     Concluding this series of encounters based on my old defunct Neverwinter game is the ultimate boss fight. Since the goal of the dungeon was investigating a cult’s plot to possess citizens with the spirits of evil outsiders, I figured the most fitting final encounter would be with a creature that is eager to possess the PCs. Originally, I paired this fight with a language substitution puzzle that could be uncovered using a series of scattered notes (your favorite “tell the story with journal entries” gimmick, from System/BioShock games). The recovered notes would reveal a key to the puzzle, allowing players to translate a magical glyph system that they would then apply to scribing a summoning circle in order to bind the Devil they were fighting. My notes were incomplete and relied on some specific circumstances so I eschewed them for the sake of this write-up.

     As before, I make references to people, places, and organizations in Neverwinter; swap these out for entities from your own campaign world where necessary.

Story Background

     Understanding the circumstances of this encounter requires a little setup. Any of these plot elements can be reworked or discarded as need be, but for brevity’s sake I’ll transcribe the situation as it was planned in my game. Beneath the House of Knowledge were a series of crypts and archives that housed ancient books, scrolls, records, manuscripts and relics. Alongside these were the bodies of priests and acolytes who served the temple in life – now comfortably resting between stacks of books in death.

     Loremaster Atlavast; the last Oghman priest to have survived the cataclysm makes his home in these crumbling archives, navigating through the sewers beneath the city when he needs to make trips above-ground. Eccentric, jealous, and more than a little snooty, Atlavast kept to himself, seeking only to preserve the knowledge that survived disaster beneath the temple’s crumbling fa├žade. 

     But ever paranoid, Atlavast was quickly made aware of the Ashmadai cult’s infiltration into the refugees living in the temple above. He began a one-man guerrilla campaign against the cultists; using old spells and traps of his own devising to discourage them from exploring the lower levels of the House of Knowledge. He began to research devils and their other fiendish kin in order to better combat his enemy…and this was his undoing.

     In a moment of uncharacteristic boldness he read from a tome in the “Dangerous Books” wing of the archives. Lurking in the pages was a spectral possession devil named Xamzael that was freed from its prison between the covers when Atlavast read from a forbidden passage. The creature immediately possessed the priest but was denied access to the surface due to ancient wards placed on the the door to the archives, trapping it there. 

     Vaguely aware of the Ashmadai thanks to its limited ability to read Atlavast’s thoughts, the devil uses its host to find a means of escaping, and has even constructed a summoning circle to call more of its brethren into the mortal plane to help. Were it to escape, the devil would happily join the Ashmadai forces in conquering the city…with the expectation of becoming Neverwinter’s new infernal king, of course.

Tactics

Much of the flow of this fight is dictated by this devil’s particular qualities, so read its stat-block carefully and get a feel for how it orchestrates the battle. Xamzael will do its best to avoid direct confrontation with the PCs at all costs. It’s first action is to attempt to possess the nearest and hardiest available target; using the host as both weapon and human shield.

The fiend begins combat with a random devil arleady summoned, and Invisibility cast on itself if it is aware of the PCs incursion. Xamzael will prioritize summoning more help when his follwers are killed. He can use the summoning circle even while possessing a foe.

Features of the Area

  Illumination: Between the menacing red glow of the summoning circle and the flickering candles positioned about the room, the chamber is filled with dim light.

  Book Stacks: Each wall (Including those around the square columns in the center of the room) is covered in rickety shelves containing moldy old tomes. Some are ancient and forgotten spellbooks, some merely treatises on the magical arts, still others tertiarily related to the craft of wizards (such as accounts of a city’s “Mage Laws” or ledgers of the names of individuals burned for “witchcraft”).

There are eight and a half foot tall, free-standing bookshelves as well. A Moderate STR (Athletics) check could be used to topple the case over, dealing 1d6 bludgeoning damage and potentially trapping a target if they are not strong enough to remove the fallen shelf.

  Tables and Chairs: Worn out tables and chairs occupy the north side of the room. Once these were used for scholars studying the potentially dangerous tomes around them. Age has worn the furniture down, and the surfaces are caked with cobwebs and dust.

  Summoning Circle: This circle is a weak gateway to the outer planes. Xamzael has been using it to call forth lesser fiends to do his bidding. He need only spend an action to loudly incant in a foul language while adjacent to the circle in order to call forth a random devil (see the chart above). Once the circle has been used it will require an indeterminate time to recharge. 

Roll 1d6: on a 5-6 another devil is poised, ready to pass through into the material plane. This will be apparent to the PCs: the creature’s growls can be heard through the veil between worlds and the glyphs of the summoning circle itself glow with a pulsing red light.

Any spellcaster who expends a 3rd level spell slot and succeeds on a Hard Intelligence (Arcana) roll can disable the circle, closing the portal for good.At your discretion, appropriate spells like Protection From Evil might also close or disrupt the circle as appropriate.

Rewards

Originally, the destruction of Xamzael was required to free Loremaster Atlavast, and the reward for this harrowing battle was acquiring a new ally. The needs of your campaign will dictate an appropriate compensation: the room is filled with scrolls, old spellbooks, and rarities. New spells, a tome sought after as part of a quest, treasure maps, or even some secreted away relic would all be suitable.
