If you have finally made it to Act 3 of Baldur’s Gate 3, you may have found the quest “Solve the Open Hand Temple Murders.” This quest requires that you investigate a murder that happened at the Open Hand Temple outside the city.
While trying to figure out these murders, you will stumble upon a group of assassins underneath the temple who happen to be working for Bhaal. Once you kill them, you will obtain a strange Flower Key; however, the game doesn’t tell you where to go next.
Updated by Erin Rice on August 15, 2023: This update includes a little more information on where to use the key. It also added pictures to help readers get a better understanding of where everything is.
What Is the Strange Flowery Key?
The key’s description reads “Flower Key (A ‘10’ is scratched on the petals).” This key is meant to open a certain place in the game to help you prove that the murder wasn’t done by the refugee that they think did it. The only issue is the game doesn’t tell you where to unlock the place in order to solve the murder once and for all. Thankfully, you can figure it out relatively easily.
Where To Use The Strange Flowery Key
If you want to use this key, all you need to do is head to the South Span of Wyrm’s Crossing’s Waypoint. There, you will find Fraygo’s Flophouse. This is the same place you can find some of the vampires Astarion is looking for as well.
Once there, head upstairs to the bedroom full of chests. Here you will be able to find a ladder leading you up to the top floor.
On this floor, you will find a wardrobe that has a slot for the key. This, in turn, opens a secret room that allows you to investigate.
What’s In The Secret Room?
Inside the room, you will find the plans to the temple, a note explaining that Bhaal is killing people and framing the cult of the Absolute, and a disguise kit. Upon further investigation, you will find blood on the floor and a body under the bed. You can take the key from the body to unlock Ffion’s Chest downstairs. Once you have done everything you need to do, you can leave and let the head investigator know what you have discovered.
