Amulet of Locking

When placed on an object and given the verbal command, the amulet casts Arcane Lock on a closed door, window, gate, chest, container, or other entryway, and it becomes locked for the duration. The container can be no larger than 4ft x 4ft x 6 ft and it follows the same properties as the Arcane Lock spell.
