My favorite item in all of fantasy is from a Russian story located here: https://www.dailymotion.com/video/x59yb47
How about the sack the caught death?
Sack
Wondrous item, legendary
This item looks like any other black bag with a rope to close it. However, when the wielder says a creature or group of creatures they can see and should their name and “then get it in!” as an action, the Creature must make at DC 20 will save. On a failure, the creature or group is sucked into the sack. the creature or group remains in the bag until the wielder lets them out the wielder can talk to the creature in the bag. A creature that saves against the sack are immune to the effects for 24 hours.
