Finding the Jar of Mystic Carrion's Lungs is an essential step for players navigating the complex quests of Baldur's Gate 3 in Act 3. Mystic Carrion is a powerful mummy lord who cannot be permanently defeated until his hidden organ jars are located and destroyed. Searching for these organs requires careful exploration and a solid understanding of the Lower City's layout.

Understanding the Importance of the Organ Jars

Mystic Carrion relies on necromantic magic to maintain his immortality, binding his soul to four distinct jars hidden throughout the city. Without destroying these items, any attempt to slay the mummy lord will result in his immediate resurrection. Tracking down each piece allows players to weaken his power and complete the quest cleanly.

The lungs represent one of the key organs required to strip away his invulnerability during the confrontation. Finding them involves investigating specific hideouts and unraveling clues left by his former servant, Thrumbo. Thorough players will want to gather every jar before starting the final battle at Philgrave's Mansion.

Location of the Jar of Mystic Carrion Lungs

The Jar of Mystic Carrion's Lungs is located inside the City Sewers, specifically hidden within the Mortuary near the Undercity Ruins. Adventurers can access the sewers through various manholes around the Lower City or via the basement of the blushing mermaid. Once inside, navigate toward the central sewer corridors to locate the secluded stone chamber.

Inside the mortuary area, players will encounter a table containing several alchemy items and ritualistic containers. The jar rests among these belongings, requiring careful interaction to acquire or destroy. Be prepared for potential traps or hostile creatures lurking nearby as you secure the organ.

How to Safely Destroy the Lungs

Destroying the organ jar requires precaution because breaking it directly can trigger an explosive cloud or necrotic damage. Using ranged attacks or elemental spells from a safe distance is often the best strategy to minimize risk to your party members. Alternatively, placing the jar in an isolated space before attacking it ensures complete safety.

Once the lungs are destroyed, Mystic Carrion's health pool and defensive abilities in the upcoming fight will be significantly reduced. Combining this achievement with the destruction of his heart, brain, and liver guarantees his permanent demise. Players can then return to Philgrave's Mansion to conclude the quest and claim their rewards.

Tips for Completing the Free the Artist Quest

Finding the organ jars connects directly with the broader storyline involving Oskar Fevras and the haunted mansion. Resolving Mystic Carrion's fate unlocks crucial items needed to cleanse the estate and free the trapped spirits. Adventurers who balance both questlines will gain unique story outcomes and valuable magical loot.

Taking the time to read scattered notes and journals throughout Philgrave's Mansion offers additional lore context for Mystic Carrion's origins. Preparing your party with fire damage and necrotic resistance will make the final confrontation far manageable. Following these steps ensures a smooth path through one of Act 3's most memorable side adventures.
