Immurk's distraction was an arcane enchantment spell that prevented people finding concealed objects by causing them to be distracted. It was useful for hiding buried treasure chests and smuggled goods.
When cast on a particular item that was then concealed, the spell clouded the mind of anyone within 50 feet (15 meters) searching for it and prevented them from finding it. If the item was hidden inside a container or beneath something else, then an affected person would not consider opening the container or looking underneath. If they were ordered to do so by someone unaffected by the spell, then they would still fail to find it. Only an item in plain sight would be discovered.
