Reaching the final chapters of Divinity: Original Sin brings players to the steps of the enigmatic Source Temple, hidden deep within the Phantom Forest. This ancient structure holds the key to advancing the main narrative, but gaining entry requires more than just brute strength or standard lockpicking skills. Source Hunters must prove their journey by collecting specific relics scattered throughout Rivellon to bypass the heavy magical defenses guarding the threshold.

The Critical Role of Star Stones and Blood Stones

The primary barrier preventing you from stepping inside the temple is a massive stone door that evaluates your cosmic progression. To satisfy the door's magical requirements, players must find and activate at least twelve Star Stones or Blood Stones throughout their entire playthrough. Each stone you uncover restores a piece of your characters' forgotten memories and unlocks new rooms within the Homestead realm.

If the temple door refuses to open, it means your current count of activated stones is insufficient for the trial. You can easily check your progress by visiting the Homestead to see how many elemental portals have opened up during your journey. Hunting down missed stones in earlier regions like Cyseal or Luculla Forest will quickly resolve this narrative roadblock.

Navigating the Phantom Forest to the Temple Entrance

Locating the physical entrance requires navigating through a treacherous environment filled with environmental hazards and powerful enemies. Players must head to the northernmost reaches of the Phantom Forest, pushing past dense undergrowth and hidden traps. Ensuring your party has high perception stats will help you spot hidden triggers and avoid unnecessary damage along the path.

Before reaching the steps, you will encounter a broken mirror maze and a series of riddle statues that test your tactical awareness. Disarming the local traps and coordinates your party members across separate pressure plates will safely clear the final approach. Once the area is secure, your party can approach the grand staircase to face the final door verification.

Solving the Inner Light Puzzles

After successfully passing the main door, the true test of the Source Temple begins inside its atmospheric, torch-lit corridors. The inner sanctuary features a complex puzzle involving three distinct elemental altars representing Devotion, Materialism, and Spirit. Source Hunters must light specific candles in a precise chronological sequence to open the inner sanctum pathways.

Paying close attention to the cryptic books and wall inscriptions scattered around the ruins provides the exact clues needed to solve these puzzles. Splitting your party to handle distant levers simultaneously will prevent the puzzle rooms from resetting unexpectedly. Successfully completing the trial grants access to the ancient wizard Leandra's secrets and prepares your team for the endgame confrontation.
