The Balcony Key is a Key Item in Bloodborne's The Old Hunters DLC.
- Key to the balcony on the first floor of the Research Hall.
- Lady Maria of the Astral Clocktower gave this to the patient, Adeline.
- Maria had hoped Adeline would find comfort in the faint breeze that carried the scent of flowers from the outside, but Adeline couldn't fathom her intentions.
The Balcony Key opens the Balcony on the ground level of the Research Hall. The Balcony resembles the Lumenflower Gardens. The Blacksky Eye is found in the middle of the Balcony.
- It is a very stubby and small key, yet intrically designed.
