Simply put, items with the Boomerang Enchantment fly (accurately) in a loop when thrown, to the target and back to the owner, akin to an actual boomerang (yet not at the same time: boomerangs generally don't come back if they hit something). If the item is dropped, left behind, or taken away, it will return to the owner's hand in the same time it'd take a boomerang to return after being thrown the same distance.
(If you're confused, by "same distance" I mean the distance between the owner and the item; the item should return back to the owner's hand (by teleporting, since the item, in this case, has not been thrown and cannot change its current trajectory to return to its owner's hand) in thirty minutes max, but the time it takes for the owner to receive the said item is determined by how fast a thrown boomerang would return to the thrower if it was thrown the same distance and that time can therefore be longer than thirty minutes).
EDIT: To clarify, if an item with the Boomerang Enchantment is left behind or taken, it will teleport safely to the owner's hand. If it has been thrown, however, the thrower better be paying attention, or said item can and will hurt them upon return.
The only items that can hold this enchantment are organic or steel items (because steel contains carbon, which is generally organic in origin) and they must be used to kill a certain monster (Boomerang Bananas, very deadly, they fling themselves at and through people) in order to gain this enchantment. With that stipulation, my question is How Beneficial Would Be The Boomerang Enchantment On Items?
Criteria for Best Answer:
- The best answer will start with a basic summary of how useful this Enchantment would be on items in general, specifically items that can be used to kill a sentient, flying, magical, and razor-sharp fruit. Since this criterion demands an idea of how Boomerang Bananas can be killed, let it be known that Boomerang Bananas can be: crushed, smothered, drowned, buried, sliced, incinerated, eaten (if peeled, which would require them to be held down), or broken, say, by a steel-coated baseball bat.
- The best answer will cover where this enchantment would be most beneficial; ie. which items would be best benefited by this enchantment. By items I mean weapons, pieces of armor (you can kill a piece of fruit by bashing it with a breastplate, yes?), perhaps valuables like cloth (you can smother a Banana with cloth, it's just difficult) or money (kind of hard to see how you'd kill a Boomerang Banana with coins without significant difficulty...)
- The best answer will cover #1 and #2 thoroughly.
- Items that were dropped, taken, or left behind teleport back to the owner, safely; the time it takes them to return depends on how long it'd take a boomerang to return to the thrower after being thrown the same distance the item was dropped, taken to, or left behind at.
