How do I unlock the hidden chest in the Underdark in Baldur's Gate 3?

To unlock the hidden chest in the Underdark in Baldur's Gate 3, you need to follow a series of steps that involve exploration, puzzle-solving, and careful interaction with the environment. This chest is located in the Myconid Colony, a key area in the Underdark, and it is hidden behind a puzzle that requires you to manipulate the environment in a specific way. Here is a detailed guide on how to achieve this.

First, you need to reach the Myconid Colony. This area is accessible after you descend into the Underdark through various routes, such as the Zhentarim Hideout or the Whispering Depths. Once you arrive at the Myconid Colony, you will notice a large, central area with several NPCs and a glowing mushroom called Sovereign Spaw. Near Sovereign Spaw, there is a hidden chest that is locked behind a puzzle involving glowing mushrooms.

The puzzle involves interacting with three specific glowing mushrooms in the correct order. These mushrooms are scattered around the area, and each one emits a faint glow. The key is to interact with them in the right sequence to unlock the chest. The correct sequence is not immediately obvious, so you may need to experiment a bit. The sequence is as follows: first, interact with the mushroom closest to the chest, then the one to the left, and finally the one to the right. If you do this correctly, the chest will unlock, and you can access its contents.

One important tip is to save your game before attempting the puzzle. This way, if you get the sequence wrong, you can reload and try again without losing progress. Additionally, make sure to have a character with high Perception or Investigation skills in your party, as this will help you spot the glowing mushrooms more easily. If you are playing as a class like a Rogue or a Wizard, you can use abilities like Detect Magic to help locate the mushrooms.

Common mistakes to avoid include interacting with the mushrooms in the wrong order or missing one of the mushrooms entirely. If you interact with them out of sequence, the chest will remain locked, and you will need to start over. Another mistake is not checking the area thoroughly, as the mushrooms can be easy to miss if you are not paying close attention.

Advanced techniques involve using spells or abilities that enhance your perception or allow you to manipulate the environment. For example, a Druid or Ranger with the Speak with Animals ability might be able to gather clues from nearby creatures about the correct sequence. Similarly, a Wizard or Sorcerer with the Mage Hand cantrip could use it to interact with the mushrooms from a distance, reducing the risk of triggering traps or other hazards.

In terms of D&D rules and mechanics, this puzzle is a good example of how environmental interaction and problem-solving are key aspects of the game. The glowing mushrooms can be seen as a form of magical trap or puzzle, requiring a combination of Perception, Investigation, and sometimes Arcana checks to solve. The sequence itself is a nod to classic D&D puzzles that require players to think logically and pay attention to their surroundings.

Specific examples and scenarios include encountering the puzzle for the first time and realizing that the glowing mushrooms are more than just decorative elements. Another scenario might involve using a character with high Dexterity to navigate the area quickly and interact with the mushrooms before any enemies can interfere. Overall, unlocking the hidden chest in the Underdark is a rewarding experience that combines exploration, puzzle-solving, and a bit of trial and error. By following these steps and tips, you can successfully unlock the chest and claim its valuable contents.
