While walking around the Shattered Sanctum in the Goblin Camp, you may have encountered a few murals across the ruins. These murals typically have four moons in a diamond shape. The shape typically indicates a full moon at the top, two half moons at the side, and no moon at the bottom. One example is above the door in the chamber you enter if you go down the stairs towards the Defiled Temple, with another one located in the locked room near the trader in the Sanctum.

This shape is what you need to match with the discs moon puzzle on the floor of the Defiled Temple. To begin rearranging the moon discs, you want to aim to get all the ones without moons on the illuminated tile, and all the full moons at the top. This is because it points at the door it will open, and the light signals daytime, hence why the base requires no moons.

So, to complete the Defiled Temple puzzle, you need the full moons at the top, and the ones at the side require two half moons along the outer edges. For reference, you can follow along with our video tutorial, showing you the step by step of solving the moon puzzle in Baldur’s Gate 3.
