Secret treasures and areas are all over the place in Baldur's Gate 3. It's virtually impossible to get every secret in any single playthrough as the combinations of choice and abilities will often limit what the party is capable of. Still, it's reasonable to want to get as many hidden treasures as possible.
Baldur's Gate 3 dangles one particular secret area right in front of the faces of gamers who get into the Toll House Basement. It's hard to call this room a "secret" because it appears on the map. But getting it open with the Stone Chairs can be a confusing and deadly process.
Solving The Stone Chair Puzzle
- Place a vase on each of the two Stone Chairs.
- Toggle Group Mode off.
- Jump over the grey plate on the floor.
- Loot the room.
- Jump back over the grey plate.
- Toggle Group Mode on.
Each Stone Chair needs to be "sat" on at the same time to open this secret area. Players can actually have party members do this or they can simply drag vases over to each chair. Do not go into the room immediately. Look for a grey plate on the floor and avoid it. When playing with friends, make sure everybody on the team knows not to step on it. When playing alone, deactivate Group Mode because a companion will automatically follow the player and step on the plate.
If players disabled the Sarcophagus trap, they'll be familiar with this classic vent trap. All the traps seen earlier are vents that don't activate until a trigger happens. These are triggered by the grey plate at the entrance of the secret room.
Players who don't want to bother with jumping can set vases on each of the vents and then walk on the plate as normal. There are two vents in the secret room itself, so be sure to place vases on those as well before safely stepping on the plate.
Baldur's Gate 3 is available in Early Access on PC and will be available on August 3rd, 2023. The PlayStation 5 version will be available on September 6th, 2023. A version for Xbox Series X/S is still in development.
