The "Fiery Dust" quest in Act 3 of Path of Exile is an essential step in progressing through the game, as it allows you to clear a path through the sewers by destroying a foul Undying Blockage. This guide will walk you through the steps needed to complete the quest.
Your journey begins as you explore the Sewers beneath Sarn. Here, you will come across a disgusting Undying Blockage, which prevents further passage. To progress, you need to find a way to destroy it.
At this point, you realize that some special substance might be required to break through this obstruction.
To clear the blockage, you need to locate a substance called Thaumetic Sulphite. Lady Dialla, found in the Solaris Temple, hints that this material is crucial for your task. She advises you to search the Docks, where this dangerous chemical can be found.
Explore the Docks until you locate the Thaumetic Sulphite. Once you have it, your next step is to return to Lady Dialla.
With the Thaumetic Sulphite in hand, return to Lady Dialla in the Solaris Temple. She will use her knowledge, learned from Malachai, to transform the Sulphite into something more potent.
Lady Dialla will craft the Infernal Talc, a powerful explosive powder capable of burning through the Undying Blockage.
After Lady Dialla has finished her work, she will hand you the Infernal Talc. This substance is incredibly volatile and must be used with care.
Lady Dialla will explain that just a sprinkle of this powder can provoke a reaction so intense that it will burn the Undying to ashes.
Armed with the Infernal Talc, return to the Sewers where the Undying Blockage resides. Use the Infernal Talc on the blockage to set it ablaze, clearing the way forward.
As you ignite the blockage, be prepared for a fight. The Undying may not take kindly to your actions, and you may have to fend off their attacks.
Once the blockage is destroyed, the path through the Sewers is cleared, allowing you to access the Ebony Barracks and continue your journey.
The "Fiery Dust" quest is a pivotal moment in Act 3 of Path of Exile, providing both a challenge and an essential progression point. By finding and utilizing the Thaumetic Sulphite, and then wielding the Infernal Talc, you can clear the path through the Sewers and continue your fight against the dark forces that plague Wraeclast.
