Titan Quest 2: Open the Mysterious Door in Fiend's Hollow

The Puzzle: The Fire Basins of Fiend's Hollow

While exploring the winding corridors and prisoner cells of Fiend's Hollow during the "Cages in the Dark" quest, you will come across a large, sealed door. This door is not part of the main quest, but it is a self-contained puzzle tied to a series of fire basins scattered throughout the cave. The solution lies in lighting these basins in a specific, sequential order.The key to solving the puzzle is simple once you know the logic: light the sets of basins in ascending order of the number of basins in each set.

Step-by-Step Guide to Opening the Mysterious Door

Follow these steps carefully to light the fire basins in the correctorder. If you interact with a basin out of sequence, its flame willimmediately extinguish, and you will have to start the puzzle over.

Step 1: The Single Basin (Northernmost Section)

• Your first target is the basin that stands alone.
• Travel to the northernmost section of the Fiend's Hollow cave.
• Just before the path takes a final corner, you will spot a single basin placed on a pedestal.
• Interact with this basin to light it. A successful interaction will cause theflame to stay lit, confirming you are on the right track.

Step 2: The Two Basins (Prisoner's Cell)

• From the first basin, make your way to the bottom-right corner of the cave.
• Here, you will find a small cell where you may have previously freed prisoners during the "Cages in the Dark" quest.
• Inside this cell, there is a set of two basins. You can interact with thesetwo in any order—the game only cares that both are lit after the singlebasin.

Step 3: The Three Basins (Mysterious Door)

• With the first three basins now lit, return to the sealed Mysterious Door.
• In front of the door, you will find the final set of three basins.
• Just like the previous step, you can interact with these in any order.

Once all six basins (the single, the pair, and the trio) have been lit inthis exact sequence, a satisfying sound will signal that the puzzle iscomplete, and the Mysterious Door will swing open.

The Rewards Behind the Door: Treasures and a Grumpy Miner

The effort you put into solving the puzzle is well worth it, as the roombehind the Mysterious Door contains both a unique encounter and somefantastic loot.

• Mopsus the Miner: Inside, you willfind a miner named Mopsus. He will not be happy to see you, as he sealed himself behind the door to escape the madness of the outside world.While he doesn't offer a quest or any items, his unique dialogue adds afun bit of lore and humor to the game.
• Two Treasure Chests: The real prize lies in the two treasure chests located within the room. These chests are not your average loot containers; they have anexceptionally high drop rate for quality gear. The chest in thebottom-right of the room is particularly rewarding, often droppingmultiple rare or epic items at once.

Solving this puzzle is not only a satisfying intellectual challenge but also a great way to acquire powerful new weapons and armor, giving you a significant edgeas you continue your adventure through the treacherous world of Titan Quest 2.
