Locate Thrumbo for Mystic Carrion in BG3

In the shadowy depths of Baldur’s Gate 3’s Lower City, the quest involving Mystic Carrion and his servant Thrumbo presents players with intriguing moral dilemmas, hidden locations, and rewarding combat encounters. This guide explores every step to locate Thrumbo, fulfill or defy Mystic Carrion’s request, and potentially dismantle the necromancer’s immortality through his scattered organs.

Encountering Mystic Carrion in Philgrave’s Mansion

Mystic Carrion resides within Philgrave’s Mansion, a foreboding structure in the Lower City. Access it by lockpicking the stone wall or slipping through a hole at coordinates X:29 Y:-166. Alternatively, a secret passphrase from a letter in Lady Jannath’s Estate Atelier grants entry without force.

Inside, Mystic Carrion tasks you with retrieving the body of his escaped zombie servant, Thrumbo, promising a reward. This initiates the ‘Find Mystic Carrion’s Servant’ quest, setting the stage for choices that branch into loyalty or rebellion.

Tracking Thrumbo to His Hiding Place

Thrumbo hides in a modest house beyond the Heapside Strand waypoint. Exit the mansion, pass the waypoint, and descend vines to the right into Smuggler’s Beach area. Enter the house to spot a trail of blood leading to a wardrobe.

Interact with the wardrobe as if looting it—Thrumbo bursts out, pleading for mercy. He reveals Mystic Carrion enslaved him and other beggars, transforming them into undead puppets. Here, decide: slay Thrumbo for Mystic Carrion or hear his tale of a ‘mummy lord’ whose heart holds the key to freedom.

• Key interaction tip: Use dialogue to learn Thrumbo’s backstory, unlocking options to side with him.
• Location precision: House at Heapside Strand, post-vines descent.

Options After Discovering Thrumbo

Choices diverge sharply:

Carrying Thrumbo’s corpse requires a strong inventory slot—assign to a lightly loaded companion.

Unveiling Mystic Carrion’s Vulnerability: The Organ Jars

Mystic Carrion’s power stems from four canopic jars containing his organs. Destroying them progressively weakens him, with the heart being pivotal. A book, ‘Funerary Jar Form and Function,’ in the Ancient Lair reveals the heart resides in Thrumbo.

Jar of Mystic Carrion’s Heart

Housed in Thrumbo. Kill him to extract, or—after reading the book—convince him to vomit it out non-lethally. Destroy via ranged attacks (explodes with 8d6 Fire damage).

Jar of Mystic Carrion’s Brain

In the Ancient Lair, Undercity Ruins. From the waypoint, head west, lockpick a stone wall, enter the room—brain jar sits on a table.

Jar of Mystic Carrion’s Liver

Adjacent gilded chest in the same Ancient Lair room. Defeat undead guardians first; also yields the crucial book and note confirming heart’s location.

Jar of Mystic Carrion’s Lungs

Graveyard mortuary, northwest of Basilisk Gate. Trapdoor at X:31 Y:21, past Mortarch Gracie Scyre. Battle undead army to access basement.

Destroy jars by dropping and igniting with fire, or ranged spells. Each weakens Carrion significantly.

Navigating the Ancient Lair and Undercity Ruins

The Undercity Ruins waypoint leads to the Ancient Lair. Proceed west into a passage, lockpick the stone wall on the right. Inside, confront undead, loot brain jar from table, liver from gilded chest. The note here proves Thrumbo harbors the heart, swaying him if alive.

• Preparation: Bring lockpicks, fire spells, undead-resistant gear.
• Tactics: Focus undead leaders to open paths.

Confronting and Defeating Mystic Carrion

With heart destroyed (mandatory for permanence), return to Philgrave’s Mansion. Carrion becomes vulnerable—engage in combat. He summons minions; prioritize jars if any remain.

Victory yields Staff of Cherished Necromancy, Armor of the Sporekeeper, Veil of the Morning, scrolls, keys. Thrumbo rewards Crypt Lord Ring (level 6 Create Undead spell).

If siding with Carrion initially, expect Torch of Revocation from gilded chest, especially if linked to ‘Free the Artist’ quest.

Rewards and Quest Outcomes

Thrumbo relocates to the mansion post-victory, selling Carrion’s wares.

Strategic Tips for Success

• Moral playthrough: Spare Thrumbo, gather all jars for easiest fight.
• Combat prep: Fire resistance for heart jar; crowd control for undead.
• Inventory management: Offload Thrumbo’s body quickly.
• Dialogue checks: High Charisma aids bargaining, persuasion.

Common Pitfalls and Troubleshooting

Avoid killing Thrumbo prematurely if pursuing his side—reload if needed. Ensure book is read before heart extraction. Lungs jar requires full mortuary clear; skip undead waves at risk of traps.

If Thrumbo vanishes after heart reveal, he escapes safely—quest progresses.

Integration with Related Quests

This ties into ‘Free the Artist’ via Oscar at Lady Jannath’s, yielding passphrase and Torch synergy. Explore Lower City fully for context on Carrion’s influence.
