Walkthrough

The location of A Mummy's Memoir.

Defeat Mystic Carrion is gained after following Find Mystic Carrion's Servant and talking to Thrumbo after finding him. Siding with Thrumbo initiates Defeat Mystic Carrion. To kill Mystic Carrion for good, his heart must be destroyed. Thrumbo mentions he was brought down to a cellar by Mystic Carrion, so the Mansion is a good place to begin. Take the stairs on the side of the mansion without entering the room that Mystic Carrion is in. On this floor, there is a locked door. Lockpicking it leads to a room full of corpses and, further north, an iron ladder (X:19, Y:-153). Take the ladder to find part of Mystic Carrion's lair. Within the lair is a book called A Mummy's Memoir which references an ancient lair in the Undercity Ruins. Alternatively, there is a hole in the wall (X:-1499, Y:-140) that can be bypassed using Wild Shape, Disguise Self, Gaseous Form, or other means.

Location of Funerary Jar Form and Function.

Using the Undercity Ruins waypoint, move west to discover a passageway (X:-180, Y:934). Entering the passageway, there is a room full of gilded chests. Interacting with them causes a horde of undead monsters to rise up and attack the party. Either battle the undead or ignore the treasure, and move to the stone wall to the north (X:-1390, Y:75). Lockpick the door (DC 20) and the party will arrive at the Ancient Lair. In the corner of the lair is a book called Funerary Jar Form and Function ((X:-1395, Y:84). Reading it reveals that Carrion's heart is inside of Thrumbo.

Return to Thrumbo and tell him the heart is inside of him. Disturbed, he will puke up the canopic jar. The jar can be destroyed using ranged attacks, as it explodes upon its destruction and deals massive damage.

There are three other canopic jars which can be destroyed to weakon Mystic Carrion, but are not necessary to permanently defeat him:

• Jar of Mystic Carrion's Lungs is in the mortuary - accessed via a hatch in the graveyard
• Jar of Mystic Carrion's Liver is in the Gilded Chest in the Ancient Lair
• Jar of Mystic Carrion's Brain is on the table in the Ancient Lair

Now that Mystic Carrion's heart is destroyed, he can be destroyed permanently. Return to the mansion and face off against him to free Thrumbo and his friends once and for all.

Once Mystic Carrion is defeated, his body can be looted. It has Scroll of Circle of Death, Staff of Cherished Necromancy, Armour of the Sporekeeper, Veil of the Morning, Crystalline Lens, and a Rusty Key that opens the gilded chest in the back of the room. The chest contains the Torch of Revocation. After Mystic Carrion's death, Thrumbo takes over as a trader, selling the same items as his former master.
