On your journey to complete the “Find the Nightsong” quest in Baldur’s Gate 3, you’ll come across a unique moon puzzle in the depths of the Defiled Temple in the Goblin Camp. Solving the sliding floor puzzle will grant you access to the Underdark, which you’ll need to complete your quests for Shadowheart.
There aren’t many context clues for figuring out this puzzle, but if you have a bit of knowledge about moon phases, you might be able to figure it out. In case you don’t have a background in the celestial, our Baldur’s Gate 3 moon puzzle guide will show you the simple solution to solving this small puzzle.
Moon puzzle solution
After you’ve dealt with the goblin priestess, you can rummage through her chambers. Beyond her room is an entrance to the Defiled Temple. You’ll know you’re on the right path when you see a door with a unique piece of art containing some large eyes and stars hanging above it. (You’ll see this art again on your way to finding Halsin, the captured druid.)
Beyond this door is the moon puzzle. To solve it, you must slide the stone discs on the floor so that all the moon phases match up in a specific orientation (full moons on top, half moons on the sides, no moons on the bottom).
If you’ve just walked into the room and are facing the fallen statue in front of the puzzle, rotate the stone discs in this order:
- Right x2
- Bottom x3
- Left x2
- Right x2
- Top x3
- Left x3
- Top x3
- Right x3
Once you’ve solved the puzzle, the room at the far end will open up, giving you access to the Underdark which lets you move forward with the “Find the Undersong” quest.
Since Baldur’s Gate 3 is still in early access, you may notice some graphical glitches, mainly the stone discs not showing the moon art on them. You can still solve the puzzle with the guidance above, but there is also a lock you can pick to the right of the door if roguish behavior is more your style.
