This walkthrough guide will show you how to solve the Gauntlet of Shar Umbral Gem Puzzle which is a part of the quest “Find Ketheric Thorm’s Relic” in Baldur’s Gate 3 (BG3).
When you first enter the dungeon, you’ll see a center statue encircled by a magical barrier that repels your character if you approach it. There are eight lanterns hanging from the ceiling need to be lowered and turn off to reveal the secret path.
The room is also filled with traps. A good perception check will be beneficial in avoiding traps from being triggered. To evade the traps, you can leap into the side rooms.
There is a little side chamber with a lever at each corner of the room. Navigate through these four side rooms, interacting with the levers to lower all of the lanterns and finally extinguish the light.
Unequip the moon lantern if you have it in your hand.
When the area is fully black, you will notice two magical rings surrounding the statue with gaps that your character may pass through to reach the Orb in the center.
To prevent your other teammates from activating the force field, It’s recommended to switch to a single character. To finish the puzzle, walk within the pattern’s lines and interact with the Umbral Gem on the pedestal.
This allows you to unlock the gateway by touching the orb.
