Navigating through the Shattered Sanctum in Baldur's Gate 3 eventually leads adventurers to the mysterious Defiled Temple. Beneath the floor of this ancient chamber lies an intricate stone disc mechanism that guards the entrance to the Underdark. Solving this moon puzzle requires a clear strategy or an understanding of environmental clues scattered around the area.
Finding the Defiled Temple Location
The Defiled Temple is tucked away in the western portion of the Goblin Camp inside the Shattered Sanctum. Accessing it usually involves passing through Priestess Gut's private quarters, either by stealth, trickery, or combat. Once inside her chambers, you must deal with her bodyguard Polma before reaching the puzzle chamber.
Players who prefer to bypass direct confrontation can look for alternative pathways through broken walls or elevated ledges. Small characters or wild-shaped druids can also find narrow crevices to slip past guarded doors undetected. Knowing these options makes navigating the temple much smoother for any party composition.
Understanding the Moon Disc Puzzle Mechanics
The floor puzzle consists of four interlocking circular plates marked with solid black dots and illuminated white dots representing moon phases. To unlock the hidden doorway, all the solid black dots must be positioned on the bottom circle where the light shines. The goal is to rotate the dials strategically to shift the dark dots into the correct configuration.
An environmental clue can be discovered nearby inside a Selunite Journal or drawn on a wall disc in a storage room. This clue explains that full moons must stand above while darkness remains at the bottom. Understanding this logic allows players to manipulate the rotating discs with precision.
Step by Step Dial Rotation Solution
To solve the puzzle quickly from the entrance archway, orient your camera directly facing the four discs. Start by turning the top dial once, then rotate the left dial once. Next, rotate the right dial twice, followed by the bottom dial three times, and finish by rotating the left dial twice.
Following this precise sequence immediately aligns all four dark circles on the bottom plate. Once the final dial locks into position, a heavy wall mechanism clicks open to reveal a secret staircase leading down.
Alternative Methods to Skip the Floor Puzzle
If you prefer not to rotate the discs, there is a bypass built into the environment. A hidden lever is located near the eastern wall close to the stairs. Passing a passive perception check reveals this locked mechanism to your party members.
Characters with high Dexterity can pick the lock on this lever using Thieves' Tools. Flipping the lever opens the hidden passage instantly, allowing you to bypass the puzzle entirely and head straight down into the Underdark.
