> [Spells (SRD p)](srd_spells.md) --- # Knock - MDR: [Déblocage](hd_spells_deblocage.md) - Source: (SRD p158) -  2nd-level transmutation - **Casting Time :** 1 action - **Range :** 60 feet - **Components :** V - **Duration :** Instantaneous - Classes: Bard, Sorcerer, Wizard ### Description Choose an object that you can see within range. 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](spells_vo.hd#arcane-lock)_, that spell is suppressed for 10 minutes, during which time the target can be opened and shut normally. When you cast the spell, a loud knock, audible from as far away as 300 feet, emanates from the target object.
