Cracked wall

The Cracked Wall is an entity in Baldur's Gate 3. It exists in the rafters of Moonrise Towers] and can be found on the main floor and interacted with after using a ladder to climb up to the rafters.

If interacted with, the interacting party member has the option to reach inside which prompts a series of skill checks (Strength, Dexterity and Sleight of Hand). If the checks are failed or if choosing to submit, the party will be pulled into the wall and transported to the Oubliette and the intacting party member gets the condition  Dislocated Shoulder.
