The object can be a door, a box, a chest, a set of manacles, a padlock, or another object that contains a mundane or magical means that prevents access. A target that is held shut by a mundane lock or that is stuck or barred becomes **unlocked, unstuck, or unbarred**. If the object has multiple locks, only one of them is unlocked. If you choose a target that is held shut with *Arcane Lock*, that spell is suppressed for 10 minutes. When you cast the spell, a loud knock, audible from as far away as 300 feet, emanates from the target object. --- ## At Higher Levels This spell does not have an upcast effect.
