To progress in Baldur’s Gate 3, one must navigate the intricate moon door puzzle at the Defiled Temple. Our detailed guide facilitates your journey through the Reach Moonrise Towers quest.

The Defiled Temple in Baldur’s Gate 3 is a crucial location where solving the moon door puzzle unlocks the path to the Selunite Outpost in the Underdark, alongside the Goblin Camp and the Nightsong Quest.

Although you do get a glimpse of the clue while inside, it can turn out to be trickier to figure out the exact pattern, as the puzzle deals with the phases of the Moon.

So, here’s a handy guide with everything you need to solve the moon door puzzle in the game.

How to solve the moon door puzzle in Baldur’s Gate 3?

To solve the moon door puzzle in Baldur’s Gate 3, you’ll need to arrange the four Stone Discs in a particular order. The order is such that Full Moons are displayed at the top disc, two Half Moons in the middle discs, and No Moons at the bottom stone disc.

You may follow the steps listed below to arrange the Stone Discs in the correct order:

1. Right Stone Disc: Rotate it once.
2. Left Stone Disc: Rotate it thrice.
3. Bottom Stone Disc: Rotate it twice.
4. Right Stone Disc: Rotate it twice.
5. Left Stone Disc: Rotate it twice.
6. Top Stone Disc: Rotate it twice.

As soon as you solve it, a door will open. This will allow you to move to the Selunite Outpost, the place of origin of the Underdark. You can take the stairs and move down to unlock the “Underdark – Selunite Outpost” waypoint.

The first instance of this puzzle’s clue is located in the Shattered Sanctum. It’s a room with a lot of barrels – and the four phases of the moon are shown in the correct order here. This room is located adjacent to Priestess Gut’s room.
